why is there a lot of stars and why can't we count them? and how do they stay there?

Answer 1

There are (not is, since that is singular and stars are plural) a lot of stars because the Universe is infinite, as far as we call tell. Since counting to infinity is impossible they can't be counted. And they don't stay there, they are constantly moving. Our sun, for instance, is moving as part of the circulation of the Milky Way Galaxy, completing a revolution in about 200 million years. The Milky Way is moving away from the center of the universe as part of the mad rush of stars trying to escape the Big Bang. Other stars in the Milky Way are doing the same, in addition to other movements within the Milky Way. I would hardly say that they "stay there".

Answer 2

Firstly we can't count them because we can't see them all. Some are too faint be seen by even the most powerful telescopes. Some are too far away to be counted. Some are too close together to be told apart and some are hidden behind massive clouds of dust and gas in space that block our view. Also the idea of counting all the stars that we can see would take hundreds of years and be a pretty boring job.

Why are there so many? Because the universe is huge - infinitely large in fact. It is also full of hydrogen gas - the stuff that fuels stars. This collects together and forms new stars. It is estimated that a new star forms every day in our galaxy alone.

How do they stay there? They are all in orbit. Swirling round the center of the galaxy. Even the sun is racing through space swirling round this center.

Answer 3

I'm not entirely sure what you're asking, but there are a lot of stars basically because the universe is a really big place. In the Milky Way galaxy, there are about 100 billion stars. The stars that we see in the sky at night are only a small fraction of that. Other galaxies range from much smaller than ours to much larger, and there are billions of galaxies.

Stars are born, live, and die over a long period of time. Massive stars have "short" lives, measured in hundreds of millions of years. Smaller stars can live for billions of years. Our sun is about five billion years old and will live for another five billion years or so.

The stars in the sky don't appear to change, but that is only because they are so far away and we live for a very short time compared to them. In one human lifetime, the only changes we can see are small and require careful study to even notice them. Over the course of thousands of years, the positions of the stars do appear to change.

Answer 4

How old are you, 10? There are lots of stars because of the singularity exploding in the beginning of recordable time. You can count the ones you can see, and the don't stay anywhere since they are constantly moving. Sincerely,
