Are the stars seen at night stars or galaxies?

The stars you see at night are actually galaxies, because there are so many stars in the universe, but their size is very small, so they can't be seen clearly from the earth.

Most of the stars we see at night are stars, there are a lot of stars, and their positions are always in motion, and we can see them from many locations on Earth.

The most in the universe are stars, you look at the sky full of stars at night, counting the stars, but you must know that most of those countless beautiful stars are stars.

Of course, it's stars, because it's said that there are tens of billions of stars. Then they are in the sky, and we can see them in the dark, which is a particularly magical phenomenon.

Of course, what we see at night is our galaxy, which can be seen with our naked eyes in the sky, and although each galaxy is very small, it exists.

All the stars visible to the naked eye basically belong to the Milky Way. In addition to the stars, we can also see a few galaxies, and we see a combination of millions to billions of stars, which also looks like a star in the night sky. There are also Mercury, Venus, Mars, Jupiter, and Saturn, the five brightest planets that are visible for most of the year.

In addition to this, supernovae and artificial objects are also visible to the naked eye.

Stars are giant spheres made of light-emitting plasma, mainly hydrogen, helium, and trace amounts of heavier elements. On a clear night, there are countless points of light in the night, and most of them are stars except for a few planets. The Sun is the closest star to Earth, and almost all of the stars that can be seen at night are in the Milky Way.

Of the approximately 300 billion stars in the Milky Way system, only a fraction of them can be observed. Human beings have a long history of observing stars, and there are many ways to observe them. The brighter stars are divided into constellations and clusters, some of which have their own names.

The brightness of a star is known as magnitude, and the brighter the star, the lower the magnitude. Astronomers also compiled star catalogs to facilitate research.

is a galaxy; These galaxies are not far away, and some of our stars around 100 light-years are binary star systems, and these stars are part of a galaxy group.

It's a star. Because the stars don't move, they keep us seeing.

This is uncertain, most of the stars are stars, they will emit light, and they should not be a galaxy.

Preface: When facing the vast starry sky at night, you can see the shining stars in the sky, many people are very curious, are the stars in the sky a single star, in fact, some of the stars in the sky are very bright, but some of the light is relatively weak. The brightest stars that can be seen at night are planets, stars appear fainter than planets, and there are many types of stars.

Most of the stars in the sky are stars, but there are some other stars that are difficult to distinguish between them, but the light emitted by stars in the sky is relatively weak.

If the sky is clear during the day, you can see a lot of stars at night, most of them are stars, and there is a star in the sky that can be seen with the naked eye about 6000 7000 stars except for meteors and artificial satellites. More than 90% of them are stars, and this data is not completely accurate because everyone's eyesight is different. The earth is a sphere, and when humans stand on the surface of the earth and observe, the stars will be scattered on the celestial sphere.

The celestial sphere is a sphere with the earth as the center and radius in human reverie, because the earth has been rotating, so the starry sky seen is not comprehensive, and most of the stars are distributed within a radius of 1000 light years. Because perseverance is a self-luminous body, and the star is farther away from the earth, the light is weaker, and the planet cannot shine and will revolve around the star, so the planet will be closer to the earth and brighter in the sky.

The stars in the sky belong to the Milky Way if they are visible to the naked eye, but there are a few other galaxies, next to the Milky Way is the Andromeda Galaxy, which can be seen with the naked eye at night even if there is no moon. In the sky, if the sky is dark, it is also possible to see a satellite, because artificial objects look very small in the sky, like stars.

Yes, stars do not have the brightness of stars, and there are many types of stars, some are stars, some are planets, or some small celestial bodies.

No, it's not just a single star, it's a whole galaxy, just because it's far away, so it's just a bright spot.

We see a lot of stars at night, not that each of them is a single star, and there are planets.

Most of the stars that can be seen at night are stars, and there are a few planets in our solar system, such as Venus, Mercury, and Mars.

There are many types of stars in the universe, but the sun is not the only one.

Stars are all gaseous planets. On clear and moonless nights and in areas without light pollution, the average person can see more than 6,000 stars with the naked eye, and with the help of telescopes, hundreds of thousands or even millions of stars can be seen. It is estimated that there are about 1500-400 billion stars in the Milky Way, and the Sun, the host star of our solar system, is a star.

Stars emit light on a similar principle to our sun, with most of the energy released by hydrogen fusion into helium nuclei, and some energy released by helium fusion. It's just because they're so far away from us that they look like gentle little stars, but in fact they're much bigger than the sun.

The planets look bright because they reflect the sun's light, but they only take up the light that is close to us, and they seem to be brighter than the stars.

Stars are spherical luminous plasmas held together by gravity, and the Sun is the closest star to Earth. Almost all of the other stars that can be seen on Earth at night are within the Milky Way, but due to their distance, these stars appear to be just fixed points of light.

The sun is the light and heat of the earth**, and when we face the starry sky at night, we only see a little bit of sparkling light, but we don't know that some of the stars also emit light and heat.

A white dwarf star numbered H1504+65 (a dense remnant of a dead star) has a surface temperature of up to 200,000 degrees Celsius, 30 times the surface temperature of the Sun.

First of all, to be sure, no. Most of the stars we can see in the night sky are stars outside the solar system that are similar to or even much larger than the sun, and the Andromeda Nebula that can be seen in the Northern Hemisphere is even more located outside the Milky Way. Only a handful of the stars we see are located within the solar system, and these can be counted.

In addition to the Sun and the Moon, two celestial bodies that can be significantly distinguished, Mercury, Venus, Mars, Jupiter, and Saturn are also visible from Earth. Among them, Mercury and Venus, since their orbits are within the Earth's orbit, should always appear to the Earth near the Sun.

In other words, we can only see these two planets in the east in the morning or west in the afternoon. Whereas, Mars, Jupiter, and Saturn are outside the Earth's orbit, we can see them anywhere near the ecliptic. These five planets are celestial bodies within the solar system that humans can see with the naked eye.

Although Uranus and Neptune are also in the solar system, they are so far away from the Earth that their brightness is below the limit of what the naked eye can see, so humans cannot see them without a telescope. Uranus and Neptune were discovered only after the birth of telescopes and celestial mechanics.

In addition, some comets that return periodically can also be seen by humans, which are also objects within the solar system. But since comets always have a tail facing away from the sun, they can still be distinguished if you look closely.

Other stars that can normally be seen are all outside the solar system, and the distance between us is measured in light years. Since their mass and brightness are generally greater than those of the sun, we can still see the light they emit even from such a distance. These rays of light have traveled in the universe for years, decades, or even hundreds of years before they reach our eyes, and the light of the Andromeda Galaxy has traveled for a full 2.2 million years, which means that we are seeing the Andromeda Galaxy 2.2 million years ago.

When this light came out, our ancestors were still living a life of drinking blood, constantly overcoming obstacles on the way of migration, and when it reached the earth, we could already observe it and study it with advanced equipment. What do you think? Anything you find amazing?

No. Because most of the stars seen at night are stars and galaxies, and only one sun in the solar system is a star, the stars seen at night do not exist in a solar system.

Yes, because they are a whole, they are attracted to each other, they are very good relationships, and they are very friendly to each other.

We know that most of the stars in the night sky are actually stars, and there are more than 400 billion stars in our galaxy, but due to the different sizes, brightness, and distance of the stars, not all stars can be seen by the naked eye. In order to describe the brightness of different stars, astronomers usually use apparent magnitude to distinguish, the first to put forward the concept of apparent magnitude was the ancient Greek astronomer Hipparchus in the 2nd century BC, he divided the 20 brightest stars into first-magnitude stars, and the faintest stars that can be seen by the naked eye into sixth-magnitude stars, and there are about 6,000 stars in the night sky of the world that can be seen by us.

Sky. Whether a celestial body can be seen by us or not, in fact, distance is the most critical factor, from far to near, the stars in the sky are actually diverse. First of all, the closest stars to us are various artificial celestial bodies, taking the International Space Station as an example, its operating altitude is about 400 kilometers, and under the illumination of the sun, the brightness of the "space station star" we see on the ground is as high as -4.

Space station transit.

Farther than the "space station star" are the planets in the solar system, equivalent to exoplanets, although they do not emit light, but they have the advantage of being close to the earth, so they also have very high brightness, such as Venus, the brightness can reach the highest. We still can't see planets when they're far away from us, such as Neptune, which has an apparent magnitude of about .

Venus. Leaving the solar system is an endless sea of stars, but also limited by distance, the stars we see with the naked eye are mainly stars in the Milky Way, and most of them are stars within a hundred light years of us, such as Sirius, Vega, etc. When the star is too far away from us, it is difficult for us to directly observe it with the naked eye, no matter how bright and large it is.

Of course, stars can also "report to the crowd", and at very long distances, the brightness of a single star is no longer enough to attract our attention, but it is still possible for a galaxy to be seen by us. For example, the Andromeda Galaxy, which is about 2.5 million light-years away, has an apparent magnitude of about Andromeda that resembles a spindle-shaped spot in the night sky. In addition to Andromeda, the Triangulum Galaxy, which is about three million light-years away, can also be seen by us, with an apparent magnitude of about .

To sum up, the stars that humans can see with the naked eye include artificial celestial bodies, some planets in the solar system, some stars in the Milky Way, and a few star systems, but most of them are stars in the Milky Way that are relatively close to us.

Thanks for browsing. Stars can be seen in the Milky Way, which represents a small galaxy, but the planets are generally not visible. Stars can be seen outside the Milky Way, but they represent a larger galaxy, and the planets are even less visible. Only specialized telescopes can see it.

Outside the solar system are stars, and outside the Milky Way are galaxies
