What is stars?

Answer 1

The basic difference between a star and a planet is that a star emits light produced in its interior by nuclear 'burning', whereas a planet only shines by reflected light.

There seem to be an enormous number of stars that are visible to the naked-eye at a really dark site but, in fact, the eye can only see about two thousand stars in the sky at one time. We can see the unresolved light of many thousands more when we look at the Milky Way, and the light of the Andromeda galaxy which can be seen by the eye comes from thousands of millions of stars.

The Sun is our own special star yet, as stars go, it is a very average star. There are stars far brighter, fainter, hotter and cooler than the Sun. Basically, however, all the stars we can see in the sky are objects similar to the Sun.

The Sun (and any other star) is a great ball of gas held together by its own gravity. The force of gravity is continually trying to force the Sun towards its centre, and if there were not some other force counteracting it the Sun would collapse. The necessary outward pressure is produced by the radiation from the nuclear energy generation in the Sun's interior.

Answer 2

If you are starring in something, it means you are the main person in it. You are the "star" of whatever it is you are starring in. When you use the word "starring", you usually are talking about a movie or t.v. show.

Answer 3

For a 4-point star, there are two methods ("a" equals how big the star will be.)

Method 1:

y1= x+a/x

y2= x-a/x

Method 2:

y1= a/x

y2= -a/x

I do not know how to make a five star function. Sorry. :(

Answer 4

Stars are massive luminous spheres of plasma held together by gravity. They emit light and energy through nuclear fusion, which occurs in their cores. Stars play a crucial role in the universe by providing the energy that sustains life on planets like Earth.
