The stars are visible in the night sky because the sun is brighter than the stars, and at night, of course, there is no sun, so you can see the stars only in the night sky
Stars : People who are very famous
Most stars are useless to us, except as occasional entertainment.
If all the showbiz stars were to take up normal jobs tomorrow it would make very little difference to anybody.
Stars : Big burning things in the sky
Most stars are useless to us, except as decoration for the sky.
We don't need them.
But one star is particularly useful. The Sun is a star, and it provides us with the energy we need to sustain life on earth. Without that energy coming in every day all plants would die, all animals that eat plants would soon die, all animals that eat animals that eat plants would die.
Most humans would die quite quickly - mainly of cold. Without sunlight it would get very very cold. A few humans hiding in nuclear bomb shelters would survive for a while.
So that is why we need one star very much.
Galaxies form from massive clouds of gas and dust, billions to trillions of times the mass of the sun. This gas is enough to form billions of stars, especially since some galaxies formed from smaller one's merging.
When you say "the solar system," are you referring to our own? If so, our solar system has only one star, and that is the sun. Our solar system consists of our single star plus all of the planets, asteroids, comets, etc. which orbit around it.
All of the other stars you see in the sky are also suns like ours -- some the same size and color, others small and white-hot, and still others huge and reddish. They just look like tiny pinpoints of light because they are so far away. And each of those stars potentially can have its own solar system, with planets, comets, etc.
As for the question of "why" every solar system has a star at its center, this has to do with the way stars are formed. Gravity causes clouds of dust and gas in space to collapse inward in a swirling motion. Most of the matter collects at the center, where the gravitational pressure causes fusion reactions and makes the star burn. The matter which does not fall toward the center of the system eventually coalesces into planets or other smaller objects, which continue to orbit around the star's center of gravity.
We need the Sun, for the energy it gives us. Other stars are like our Sun - and it is already confirmed that many of them have planets. Perhaps most, but that is not known for sure yet. It is not known whether many of those planets have some kind of life. If they do - and this is but speculation for now - then God's purpose is to have a great number of planets with life.
Not sure about the Moon; perhaps for variety. It's role might not be as essencial as that of the Sun.
There are probably many parts to the answer. One part of the answer is that gravity pulls things together; also, that there is a lot of hydrogen in space. For more information, you may want to check the Wikipedia article (or some other source) on "protostar". Once you know HOW stars are formed, it may become clearer WHY they are formed.
I doubt that anybody knows why there are stars in the universe, but I'd say that it was to keep all the planets that support life warm.
It seems that the matter in the Universe just has the natural tendency to clump together, due to the force of gravity, forming galaxy clusters, galaxies, star clusters, and individual stars.
There is only one star in the Solar System - Our Sun
The moon is not a star. The moon only reflects the suns light. Only stars make light. Our sun is a star.
The Sun is a star. A moon is a (moon) also known as a: satellite.
The Sun, other stars and the Moon.
The sky is too brightly lit for stars to be seen. At pre-dawn, stars and the moon may just be visible. As the sun rises and the sky brightens, stars and the moon fades away.
we do not see stars in the daylight because skylight overwhelms them. We see the moon in sunlight. The sun cannot block the moon unless in eclipse
I believe the sun, moon and the stars where the Arawaks god
The Sun, Stars and Moon in the sky where created in the begining by God for signs and seasons
Astronomers study the moon, sun, and stars.

written in the book of GENESIS: GOD made the sun, moon && stars. no need to be elaborated, it's clearly stated. XD
When the sun sets, you can watch the sky as the stars and moon appear.
Neither. The sun, moon, and stars are all well outside the Earth
because the moon and stars ;it has a light color only;; while the sun has much strong color;;; so if there's a sun the moon and stars ;;did you cannot appear bec. the sun has much light under the moon and stars
No
Comets were most likely made on day 4 of creation when God created the sun,moon and stars.
