Are stars planets? Are stars or planets

The arrival of night is due to the fact that the autobiography of the Earth is that we are on the opposite side of the Sun, the Moon can reflect the sun's light, but the Moon is a satellite of the Earth, not a planet. The reflective planets we usually see are generally Venus at dawn and Chang Gung at evening (in fact, they are formed by Venus reflecting the sun's light at different times), and most of the stars we see at night are stars. Most of them are brighter than the sun, but they are too far away from us, and writing that they are still moving away from us at a rapid pace so we feel that they are not as bright as the sun, and much smaller than the sun.

It is because they are constantly moving away from us and they are very far away from us that there is very little light reaching the earth, and at night the sun cannot find the side of the earth we are on, so the night is pitch black.

What kind of stars? If it's self-luminous, it's a star, and if it's reflective, it's probably a planet or a moon!

The vast majority of the stars we see at night are stars. What we commonly refer to as stars generally refers to stars that are capable of emitting light on their own. If it is a planet, etc., it should be reflected in our eyes by nearby stars.

First of all, I don't know how you define the planet. Secondly, I don't know what the difference is between the stars and the stars in your eyes ...

In the night sky, most of the "bright spots" that can be seen with the naked eye (I originally wanted to use "stars", but I am afraid you will misunderstand them again) are stars. There are several planets (it seems to be five, I can't remember exactly), all of which are large planets or near-Earth planets in the solar system. You should be able to see artificial satellites and occasionally meteors.

The moon is just a satellite of the Earth.

Theoretically, aliens are supposed to exist, but until now, they have not been discovered

It's possible to see a UFO, because UFO stands for Unidentified Flying Object, and you can call it a UFO as long as it's flying and you don't know what it's about.

If you want to see aliens ... Well, that's up to you.

The final piece of advice: if you don't have a lot of money and want to use it to light a fire, it seems that there is no need to buy the 4000 telescope. Moreover, no matter how you look at it, it is unlikely that an optical telescope will be able to see a large sky man on the moon.

Not to mention the farther planets, and of course if you're an avid astronomer, I can't help it. You can take care of yourself

There are stars and planets! Most of the stars you see at night are stars!

The surface of the planet does not glow! So basically can't be seen! It will be sent out with the light of the stars!

Of course not, but there are some things like the moon, the Earth's satellites and some planets in the solar system!

Not necessarily, there are planets, stars, moons, etc., but most of what you see are stars.

Yes, most of the stars we see are stars.

The vast majority of the stars we see at night are stars. But there are also some planets.

In addition to Mars and Venus, all stars are seen, as well as extragalactic galaxies.

Not necessarily, mostly stars.

Stars are both stars and planets.

The stars that people see are both stars and planets, as well as comets, white dwarfs, small celestial bodies, etc. There are more than 6,000 stars that people can see with the naked eye, except for the five major planets in the solar system, meteors and comets, pure sails, and all of them are stars. Stars react inside themselves and radiate energy into space in the form of light, such as the sun.

The brightness of a star is often expressed in terms of magnitude. The brighter the star, the smaller the magnitude. The brightest planet is Venus, the fastest star orbiting at more than 240 kilometers per hour, and h1504+65 is the hottest white dwarf.

Although the star is solid on the surface, it is also deformable because the solid particles are also movable, which makes it possible to transform it into a spherical shape.

Introduction of natural satellites

A satellite refers to a natural or man-made object that orbits around a planet, and the Moon is the most obvious example of a natural satellite with a wheeler. In the solar system, except for Mercury and Venus, all other planets have natural satellites. There are at least 160 known natural satellites in the solar system, and natural satellites are planets that orbit planets, which in turn orbit stars.

For example, in the solar system, the sun is the star, and our earth and other planets revolve around the sun, the moon and the earth.

1. Planets such as Celestian orbit our earth and other planets, and these planets are called natural satellites of the planets. Jupiter has the largest number of natural moons, 17 of which have been confirmed, and at least 6 more have yet to be confirmed. Natural satellites vary in size and vary greatly from one another.

Some of them are only a few kilometers in diameter, for example, the two small moons of Mars, and some small moons on the periphery of Jupiter, Saturn, and Uranus. There are a few others that are larger than Mercury, for example, Enceladus.

6. Ganymede and Ganymede, both of which are more than 5,200 kilometers in diameter.

Planets: Mercury, Venus, Mars, Jupiter, Saturn, Earth, Uranus, Neptune.

1. Mercury. Mercury is the closest planet to the Sun, its average orbital radius is about one astronomical unit (the length of an astronomical unit is the average distance from the Earth to the Sun), and its size is smaller than the Earth, with a radius of 2440 kilometers, and the mass is only Earth, you are not mistaken), so the gravitational pull on the surface of Mercury is only 40% of that of Earth.

2. Venus. Venus is very similar to our Earth in mass, volume, density, first of all, the radius of Venus is about 6000 kilometers (the radius of the Earth is 6371 kilometers), and the mass of Venus is about 500 billion billion kilograms (equivalent to 85% of the mass of the Earth), so the average density of Venus is 5200 kilograms per cubic meter (the average density of the Earth is 5500). The surface environment of Venus is also very harsh, with a thick atmosphere rich in greenhouse gases making the greenhouse effect of Venus extremely strong, with a surface temperature of nearly 500 degrees Celsius.

3. Mars. Mars has a radius of 3,400 kilometers and a mass of 11% of the Earth, although it is not as large as the Earth in terms of volume and mass, but Mars has had the Earth's current climate and environment for billions of years, and perhaps there was life on Mars at that time.

However, due to the continuous decline in the temperature of the inner core of Mars, the magnetic field gradually disappeared, so that the solar wind can be unscrupulously intruded, coupled with its own gravitational force is not strong enough, resulting in the gradual disappearance of liquid water and atmosphere on the surface of Mars, and finally has today's desolate appearance, but if one day in the future human beings want to establish colonies on alien planets, among the eight planets, Mars is still the first choice.

4. Jupiter. Jupiter is the largest of the eight planets, and in terms of volume, it takes 1,400 Earths to fill a Jupiter, and Jupiter's mass is twice the mass of the other seven planets combined (but still much smaller than the Sun, only one-thousandth the mass of the Sun).

Jupiter's rotation is also very special because Jupiter does not have a solid surface, so the way we judge Jupiter's rotation is determined by the movement of its surface atmosphere, and Jupiter's atmosphere at different latitudes does not move consistently, showing a way known as "poor rotation" (the same is true for the rotation of the Sun), with a rotation of 9 hours and 50 minutes at the equator and 9 hours and 55 minutes at high latitudes.

5. Saturn. Many people will think that the material that makes up Saturn's rings should be solid matter similar to asteroids, such as large "stones", but in fact, it is "ice" that makes up Saturn's rings, and the volume of these ice blocks is not large, basically between millimeters and meters, and the thickness of Saturn's rings is only a few tens of meters, but its distribution range is quite wide, with a diameter of 200,000 kilometers.

Asteroids (or minorplanets) refer to celestial bodies in the solar system that similar planets orbit the sun, but are much smaller in size and mass than planets, and the vast majority of asteroids are concentrated in the asteroid belt between the orbits of Mars and Jupiter.

As of December 31, 2020, 1026572 asteroids have been identified in the Solar System (including Outer Neptune), about 57% of which have been officially numbered, but this is likely to be only a small fraction of all asteroids.
