The only galaxies that can be seen are the Andromeda Galaxy, M51, and the Large and Small Magellanic galaxies. Most of the sky is filled with Milky Way stars and solar system planets, as well as a few nebulae and star clusters in the Milky Way. Because we are inside the Milky Way, there are not many extragalactic galaxies that can be seen with the naked eye.
There are quite a few nebulae and star clusters visible to the naked eye, such as the Orion Nebula in Orion, the Herculese globular cluster in Hercules, the Pleiades in Taurus, and the Lagoon Nebula in Sagittarius. But with the naked eye, it is only a small dot, and even with a telescope, it is only a small cloud of white gas.

Most of the stars in the sky are stars, because stars can emit light on their own, so they can be seen from a distance, and secondly, Mercury, Venus, Mars, Jupiter, and Saturn can also be seen often in the solar system, but these celestial bodies are moving in the air, and the dot area is larger than that of stars, which can distinguish them. Nebulae do not emit light and are difficult to see with the naked eye, and galaxies are made up of countless stars that need to be viewed with high-powered telescopes.
-
Most of them are stars, some of them are nebulae or galaxies.
-
Fixed star! It could also be a near-Earth planet, such as the Morning Star, the Moon!
-
Only stars shine, and since you are talking about stars in the sky, they can only be stars, and as far as you can see with your eyes, they are all the closest, star clusters, so far away that you can't observe them with the naked eye.
-
It's all possible, but most of them are stars!
-
The vast majority of stars are stars.
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.

The sparkling stars in the night sky, they are very varied, not a certain kind of group, for the stars in the night sky, they may be both a star or a galaxy, but also may be a satellite, planet, meteor, etc., of course, most of the stars we see at night should belong to stars or galaxies, after all, it is because they have a strong ability to shine, and occupy a decisive size, can make their own brilliance glow into the space of the universe.
Whenever the weather is clear in the night sky, there will be dense stars in the sky, and they are faintly distributed throughout the night sky, so beautiful! The vast majority of stars in the night sky are stars, far more than other types of celestial bodies. On a clear night without moon and lights, we notice a large number of stars.
Most of these stars are stars, and they are mostly 2,000 light-years away, while only a few blue supergiants are still visible at a distance of several thousand light-years.
Supernovae are the distant stars that we can see, but the ones that can be seen farther away than them are galaxies, such as the Andromeda Galaxy, which is about 2.6 million light-years away from us, and looks like a spindle-shaped elliptical spot in the northeast sky, in addition to the galaxies visible to the naked eye, there is also the Triangulum Galaxy in the northwest night sky, which is farther away from us, about 2.9 million light-years, and it looks very vague, but it is the farthest object that we can see with the naked eye. The Great Magellanic Galaxy and the Small Magellanic Galaxy in the Southern Sky Region are relatively close to us, only more than 100,000 light-years, but they are two dwarf galaxies and satellite galaxies of the Milky Way, and they are not large.
Although there are many stars in the night sky, but the brightest in addition to the moon are planets, such as Venus, its brightness is 14 times that of the brightest star Sirius, and it is the brightest celestial body in the night sky except for the moon, which is also due to its very close to the earth, in addition to Jupiter is also very bright, and Mars, Saturn is also very bright, Uranus is not bright, but it is barely visible to the naked eye, but Neptune is not visible, Mercury is very close to the sun, often drowned in the sun's brilliance, So it's rarely seen.
The vast majority of stars in the night sky are stars, far more than any other kind of celestial body, and on a very clear night when there is no moon and no lights, we can see an extremely large number of stars, most of which are stars, most of them are within 2000 light-years of us, and only a very few blue supergiants can still be seen at a distance of thousands of light-years.

Some represent a star, some represent a galaxy. Some galaxies are so far away from Earth that only a small bright spot can be seen. Some stars are closer to Earth, so we can see exactly where they are and how bright they are.
-
The stars that we can see with the naked eye are all separate stars. Because only stars can shine, and heat can be seen by people on Earth. There are many asteroids in the star system that cannot be seen.
-
The stars in the sky represent the stars, not the galaxies, each star represents the stars, and the galaxy mainly refers to the gathering of many stars.
-
It's a star.
The planets can only be seen with the naked eye Mercury, Venus, Mars, Jupiter, and Saturn; There are also galaxies, star clusters, nebulae, and so on, instead of stars.
Reason: Rental source attack stars will crack and shout light, as long as the light is strong enough, you can see, the planet only reflects and does not emit light, so it is relatively weak, and only those who are close can see it (such as Venus), and the nebula star cluster is all luminous, so you don't explain the cheat.

1.Are the stars in the sky stars or planets.
Stars in the sky have long been a topic of interest to mankind, are they stars or planets? First of all, it needs to be clear that stars are completely different celestial bodies from planets. Stars are celestial bodies that can generate energy on their own and maintain their brightness and temperature through nuclear fusion reactions. Planets, on the other hand, are celestial bodies that orbit stars in elliptical orbits and do not produce their own light and heat like stars.
2.Difference Between Stars and Planets.
The most obvious difference between stars and planets is their brightness, with stars having their own light, whereas planets can only reflect the light of stars. In addition, planets are usually relatively small objects, while stars are very large objects. In the universe, stars resemble giant fireballs, and planets resemble small rocks.
3.Classification of stars.
Stars can be divided into spectral types A, B, F, G, K, M and other types according to their spectral types, among which m-type stars are the most common one. According to its brightness, it can be divided into supergiant simple high stars, giant stars, subgiant stars, main-sequence stars, etc. In addition, stars can be further classified based on their age, mass, and other characteristics.
4.Classification of planets.
Planets can be divided into two types: inner planets (such as Mercury, Venus, Earth, Mars, etc.) and outer planets (such as Jupiter, Saturn, Uranus, Neptune, etc.) according to the position of their orbits. According to their mass, density, and other characteristics, planets can be divided into Earth-like planets, Jupiter-like gas planets, and Neptune-like icy planets.
5.Observe the stars in the sky.
We can observe the stars in the sky with the naked eye, and many stars can be seen in areas with less light pollution, such as the Big Dipper, Lyra, etc. At the same time, we can also observe planets through telescopes or astronomical telescopes, such as the rings of Saturn, the moons of Jupiter, etc.
6.The stars and planets are a sign of the shadow of humanity.
Stars and planets are not only important in science, but also in human culture, history, religion and other fields. In ancient times, people learned about celestial phenomena, the future, etc., by observing the stars; In modern times, people use satellite technology to achieve communication, weather forecasting, navigation and other functions. At the same time, the beautiful landscape of the starry sky has also become a kind of way for people to pursue happiness, and human beings have never stopped exploring and researching the stars and planets.
7.Conclusion. To sum up, the stars in the sky are stars and not planets.
Stars and planets are very different in terms of physical properties and classification, and the position of stars in the universe is very important. Through continuous observation, research and exploration, we can better understand the different celestial bodies in the universe and better use and protect the resources of the sky.
Some of the stars in the sky are stars, some are planets, or some other celestial bodies. Stars naturally emit light, while others do not. >>>More
Most of the stars in the sky are stars that glow on their own, so they are very bright. >>>More
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. >>>More
