galaxies
Billions of stars make up galaxies. Galaxies are vast systems of stars, planets, gas, and dust that are held together by gravity. Our Milky Way galaxy, for example, consists of billions of stars including our Sun.
Because they are billions and billions and billions of miles away from us.
The five medium stars are the Sun, Alpha Centauri A, Sirius A, Vega, and Capella. These stars have masses and luminosities greater than average stars like our Sun, but are not as massive or luminous as giant stars.
A system of billions of stars held together by gravity is called a galaxy. The one we live in is called the Milky Way galaxy.
Stars are nonliving. They cannot live at all. However, they do last and exist for billions of years; our own for example has been going for 4.5 billion and is expected to go at least that amount again.

A galaxy contains billions of stars. A universe contains billions of galaxies.
You can't list "all the stars" in a constellation; there are billions upon billions of them.
The universe.
Because they are billions and billions and billions of miles away from us.
every galixy has billions of stars
Stars are suns, We are in the Milkey Way Galaxy, We have only one Star. There are BILLIONS and BILLIONS of Stars in space.
No. The universe contains billions of galaxies including our own, and each galaxy contains billions of stars.
There are only 6,000 stars in the night sky which are viewable with the naked eye. But there are billions if not trillions of stars in the universe. Remember one star in every solar systen, millions to billions of stars in each galaxy, and billions of galaxies in the universe.
There are billions of stars that are not on the main sequence.
Carl Sagan compared the stars to "billions upon billions of suns." He often used this analogy to convey the vastness and number of stars in the universe.
The light from the stars travels billions of years. Most of the stars we see are already gone, but the light from them us still traveling.
