Why are there stars and moons in the sky? Are all the stars in the sky smaller than the moon?

Because so, science makes sense.

Agree with the statement upstairs, there are many planets in the whole universe, we are on the earth, looking outward, there are of course many planets visible to the naked eye, this question is so strange, it is like asking why there are so many people around us.

Very simple. It's just a little bit of light for the night, and there's a little bit of romance.

Children, stars are stars like the sun that shine because they are too far away from us. So we look like tiny stars!

Got it?

No, every star you can see in the sky is bigger than the moon.

The moon is only a satellite of the Earth, with a diameter of just over 3400 kilometers, which is only 1 4 times the size of the Earth. And the Earth is only a small planet in the solar system, with a diameter of just over 12,000 kilometers. The Sun is the largest planet in the solar system, with a diameter of about 140,000 kilometers.

In the universe, planets larger than the Sun abound, but because they are so far away from us, they seem to be small bright spots one by one.

The stars that can be seen with the naked eye and ordinary telescopes are all smaller than the moon. Because the Moon is only 380,000 kilometers, and the nearest Venus, the closest is 4,500 kilometers. As a result, stars smaller than the moon cannot be seen with the naked eye or ordinary telescopes, so all the stars in the sky are smaller than the moon.

If we talk about apparent diameter, the answer is yes, the perspective of the moon on the earth is approximately. Objects other than the Sun are a point of light (the naked eye cannot distinguish their perspective), and if there is an object on Earth that has a perspective greater than that of the Moon, it is an absolute disaster for the biosphere (except for comets).

But if you talk about real size, almost all the stars are bigger than the moon. With a few exceptions, the sky is full of stars, and to be able to initiate nuclear fusion, it would require at least a double the mass of the Sun (330,000 times the mass of the Earth), which would obviously be orders of magnitude larger than the Moon. The remaining bright planets are also larger than the Moon.

But I'm using "almost" here, with the exception of asteroidsThe largest asteroids are barely visible to the naked eye at opposition, and their diameters are smaller than those of the Moon (but if you are not a skilled astronomer, you will not pay attention to the extremely faint points of light).

No, it's just that they are all farther away than the moon, so they all look very small, it's like you let a person with a height of 1.8 meters go 500 meters away, and then hold a table tennis ball in your hand, the table tennis ball in your hand is much bigger than 180 people, the mountain in the distance is the same length as your thumb, and the people standing on the tall buildings below are as small as ants, so it's not that the moon is bigger than them, in fact, the Venus you often see is much bigger than the moon, in fact, Venus is about the same size as the earth, It's just that it's too far away, so it looks like a small star.

No. It's just that the moon is a satellite of the Earth and is very close to us, so it looks bigger than the moon. The principle of perspective is the same as that in painting, which is near and large, far and small.

The stars we can see are much farther away from us than the distance between the Moon and us, and the nearest Venus is hundreds of millions of times the distance between the Earth and the Moon when it is closest to us. So, the stars we see, even though they look small, are actually bigger than the moon.

The stars in the sky appear to be only a few points, but in fact most of them are stars, and only a few planets near the Earth can be seen by the naked eye by the reflection of sunlight. Compared with the sun, some stars are several times larger than the sun, or even ten times or dozens of times, and the smallest planets in the solar system that can be seen by the naked eye are also several times larger than the moon, that is, meteors are some small celestial bodies, some are called asteroids, and some are meteorites, which are smaller than the moon.

Some of the stars in the sky are bigger than the moon, some are smaller than the moon, but the distance from the earth is different, so we see that it is smaller than the moon.

There are 2 types of feelings.

If it's the apparent size (the size when looking at it with the eyes), then the answer is "yes".

If it is according to the absolute size, that is, the true size, then the answer is "no", the real size of celestial bodies is smaller than the moon (asteroids, dwarf planets, etc.), more than the moon, such as the sun, stars are larger than planets, at least 100,000km, planets are also larger than the moon, and the size of other deep-sky objects is basically calculated in light years.

On the contrary, all stars visible to the naked eye (excluding satellites, comets, and meteors) are larger than the Moon, and most of them are much larger.

Some, such as Vesta, which is visible to the naked eye, is an asteroid smaller than the Moon. But most of the stars are larger than the moon.

Except for the Sun and the Moon, except for Water, Gold, Fire, Wood and Saturn, most of the other stars you see with the naked eye are larger than the Sun, let alone the Moon.

This is related to the distance, and the farther the distance, the smaller the shape will appear.
