Most of the stars we see are the vast majority of stars that can be removed

You can "remove" it But, note: most of what we see are stars, but there are also a very small number of planets, and we only see five planets with the naked eye, Mercury, Venus, Mars, Jupiter, and Saturn. Uranus is looming, and Neptune is too far away to be seen without the help of a telescope.

There is also the Moon and Sputnik. There are also some nebulae and galaxies but they are so far away that we can only see one point. Mercury is the most difficult planet to observe, and it is so close to the Sun that it is often submerged in its radiance.

When we can see Mercury, only around the spring and autumn equinoxes, when the angle between Mercury and the Sun is at its maximum, it appears in the west before sunset and in the east before sunrise and sunrise, and the best time to observe Mercury is from the end of March to April when the sun sets, there is an hour of observation time. The satellites can only be seen at dawn and when the sun sets, because the sun's light can be reflected on the satellite, and at night, we turn away from the sun, and the satellites can't reflect the sun's light, so we can't see the satellites. How can we tell if a star in the sky is a star or a planet, the main thing is to see if it is like you blinking, the star is very far away from us, when the light of the star enters the atmosphere, it is affected by atmospheric fluctuations, and there will be a twinkle feeling, as if it is winking at us.

The planets are relatively close to us, they all reflect the sun's rays, forming a bright large circle, although they are also twinkling, but some of the points of light become brighter, some of the points of light become dim, and they replace each other, so there is no feeling of blinking. There are also planets that revolve around the sun, so they move between constellations every day, and usually a star moves more in a short period of time between constellations. There are also planets that can be distinguished by color, Saturn is yellow, Mars is red, and Mercury, Venus, and Jupiter are yellowish.

No, most of the representations are not all, and if you remove the meaning, you will see all the stars, and you can't show rigor, so you can't remove them.

There are not as many stars as there are stars.

At present, human beings do not have the ability to use these stars, because the level of human civilization is only the level of human civilization, and even the earth is not fully controlled. Natural and man-made disasters and tsunamis* threaten the survival of mankind at all times. When humanity reached the first level of civilization and the earth was completely controlled, they began to use the stars.

The meaning of the earth's existence is because the earth itself exists, and it has nothing to do with human beings, because human beings are the sixth generation of creatures on the earth, and the earth definitely does not exist because of human beings. On the other hand, the reason why human beings can exist is because of the existence of the earth as a carrier, so human beings are not the masters of the earth, but only borrow places like the earth to reproduce.

According to this definition, there are currently eight planets in the solar system, namely: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Charon, originally thought to be a moon of Pluto, is also a temporary celestial body.

The International Astronomical Union's Committee on Planetary Definitions said it did not rule out that more eligible objects in the solar system would be listed as planets in the future. Currently, there are more than 10 celestial bodies in the solar system that may fit the definition of planets on the list of astronomers' observations.

As can be seen with the naked eye, all the stars in the sky are stars, except for a few planets in the solar system. These stars are more than 4 light-years away from us, and the longest is 7,500 light-years, each light-year away from a trillion kilometers. If you are interested, you can figure it out for yourself.

The star is a giant burning plasma with nuclear fusion taking place in its center, that is, the energy released by nuclear fusion is constantly radiating light and heat. The Sun is a star, and it is the one that we use the most and is indispensable.

The center is engaged in hydrogen fusion all the time, 600 million tons of hydrogen are fused into 100 million tons of helium every second, and 4 million tons of material energy are released. The earth is named that way we did, but we ruled out the subjective reasons for this naming. It is an objectively existing entity, like the apple in our lives.

You can call it an apple or you can call it a persimmon. You can call him anything, but this thing is real and doesn't change the entire solar system because of your name. In a small galaxy there is a sun, that is, a star with eight moons, Mercury, Venus, Jupiter, Saturn, Uranus.

The meaning of existence is to illuminate the planet, to illuminate the universe, to carry out better purification, to maintain world peace, and to ensure the survival of this world. Each star has its own meaning of existence, and part of it may also be to bring more beauty to mankind.

It is not for people to look at the stars, the purpose of the existence of these stars is for people to discover, and then explore the process of star evolution, and then understand the structure of the stars and grasp the laws of the universe.

1.Stars are not created for human appreciation, but they are indeed useful for humans. 2.

The sun is a star, and without it, humanity would not be able to survive on Earth. 3.Before the birth of the solar system, the massive stars of the previous generation synthesized heavy elements, which were thrown into the solar nebula during supernova explosions, and the heavier elements than helium in humans came from this.

It can be said that without stars there would be no human beings.

The rotation of the Earth. The speed is very fast, why can't we see the stars moving when the earth is spinning so fast, first of all, because the earth is too big, and the gravitational force of the center of the earth is very large, we can't feel the earth moving at all; Why do people look at the stars without moving, because the stars are so far away from us, and you can't see that they are moving!

As the Earth rotates, the alignment of certain stars in the night sky actually changes significantly, and they are the planets in the solar system. Since the Earth and other planets revolve around the Sun and are in close proximity, the relative positions of the planets in the night sky change significantly over time, and the planets travel through different constellations. There are only five planets visible to the naked eye, including the amenity star.

That is, Venus, which appears before sunrise. In addition to the five planets of the solar system.

In addition, the stars in the night sky are all stars far away outside the solar system. While their actual brightness may be higher than that of the Sun, they are so far away that the human eye cannot discern their details, and they appear to be just bright spots.

Revolution in the earth.

The relative positions of the stars do not change visibly to the naked eye. This is because stars are so far away from us, tens of trillions of kilometers (light years) away, that they have parallax.

It's too small. Even on other planets in the solar system, the sky seen by the observer will not make any difference. However, the parallax of the closer stars can be measured.

The stellar parallax angle can be measured by observing the offset of the star relative to the background sky over a period of six months. Due to the distance between the sun and the earth.

is known, according to trigonometric functions.

The distance of the star can be calculated, which is the earliest stellar ranging method - trigonometric parallax method.

On the other hand, with the solar system in the Milky Way.

, other stars move relative to the solar system, causing their relative positions in the night sky to slow down and change permanently. It's just that this change is so small that it's hard to see in a short period of time.

Unless a star like Barnard's star has extremely fast self-motion, its position relative to the background sky will change significantly from year to year. The star, which is currently about 6 light-years away, is moving at a high speed of 143 kilometers per second towards the Sun. In about 10,000 years, it will move to a place where it is only light-years away.

This is because the stars we see are actually celestial bodies in outer space, or galaxies, which are constantly in motion.

This is due to the rotation and revolution of the earth, and the position of the stars changes through the rotation from the earth.

It's because we're so far away from the stars that we can't see them even if their positions are constantly changing.

Because the stars are celestial bodies like the sun, celestial bodies rotate all the time.

Right. Just as a child is born every moment on earth and someone dies every moment. The only constant in the universe is that everything changes. Pure hand hitting, looking.

Right. It has been 100 million years since the birth of the universe. But 4.6 billion years ago, the Sun did not exist, but a large nebula from which the Sun and the eight planets were born.

But stars can't burn forever. There is no such thing as a "perpetual motion machine" in the universe. Stars can remain stable for billions or even tens of billions of years.

For humans, this time is enough.

There are many stars born in the universe all the time, and at the same time, many stars disappear Hello, homeowner. The universe is exactly what you say: stars are born and destroyed all the time.

This is the circulation of matter and the flow of energy in the universe. In line with Hawking's view of the universe, you can see the destruction and rebirth of stars through a space enthusiast's cosmic telescope! Break a leg!

In the vast universe, there are many celestial bodies that we do not know, some of which are visible to our naked eyes, some of which we need to see with the help of some special instruments, and what can be seen with the naked eye is the sun closest to our earth, and some starsSo are all the stars we can see with the naked eye stars? I think most of what we can see with the naked eye are stars, but that doesn't mean all of them.

No. Because some of the planets we see with the naked eye are galaxies, they are not necessarily stars.

The vast majority are stars, but not all of them. Except for the planets of gold, wood, water, fire, and earth, the others are stars and nebulae.

Stars are spheres that emit light on their own, and most of the stars are in the banking system, far away from the solar system, so they are stars that can be seen by the naked eye.

Kinman dwarf galaxy, aka PHL 293b. nasa, esa / hubble, j. andrews (u. arizona)

The Kinman dwarf galaxy is located 75 million light-years from Earth in the constellation Aquarius. This galaxy is so far away from Earth that astronomers have difficulty distinguishing the individual stars in it. But somehow, people can still detect special signals from some stars in the galaxy.

Between 2001 and 2011, astronomers were able to find a special imprint in the spectrum of this galaxy called a so-called bright blue variable star.

This star is 2.5 million times brighter than the Sun and is a very unstable star whose spectral signature and brightness change randomly. Although unstable, astronomers have a way to determine its existence through a special trace.

But miraculously, when astronomers tried to study it again, it disappeared.

In August 2019, researchers pointed their telescopes at the galaxy again, but they could not detect any signals that would prove the star's existence. A few months later, the same was true for X-ray observations. The star just disappeared inexplicably.

After analyzing old data from 2002 and 2009, the researchers found that the star was in the midst of a strong eruption period, which was likely to end after 2011. Bright blue variables are susceptible to eruption, and their material loss increases dramatically during the eruption period, as well as a significant increase in brightness.

Based on observational data and theoretical models, the researchers believe that there are two possibilities that could lead to such an outcome. The first possibility is that the eruption of the bright blue variable star caused it to become a faint star, and at the same time obscured by a large amount of dust.

The second possibility is that the star became a black hole. This is bizarre because the current general understanding of massive star death is that most of them explode into supernovae at the end of their lives. But the brilliant blue variable star did not go through this phase.

So what exactly is this star going to **?

Hello! Most are stars because they emit light on their own and are generally larger and easier to see. Most planets do not emit light on their own (reflect the light of stars) and are smaller, with the exception of a few planets in the solar system.

Planets in outer galaxies are rarely visible. Hope it helps.

It's not easy to type, adopt it!
