An astronomer is a scientist who specializes in mapping and studying the fixed stars in the universe. They use telescopes and various instruments to observe and collect data on the positions, movements, and characteristics of stars to better understand the cosmos.
Pretty sure it was Ptolemy.

Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
Sweety! there are a millions of stars in the whole universe and of course they have their own groups but they are named by the scientist who watch and observed them everyday so it's depends on the scientist what named they be and it's not easy to just name them they have some marks and qualification in order for them to get the right name
A galaxy contains billions of stars. A universe contains billions of galaxies.
that stars are moving away from us, as if flung out from an explosion, helping support the big bang theorey and showing us that the universe is expanding
All stars and galaxies are in the universe.
There is no singular star in the center of the universe. Our universe is vast and does not have a center. Stars are spread throughout the universe in galaxies, and our sun is just one of the billions of stars in the Milky Way galaxy.
One way scientists use to calculate the age of the universe is by measuring the rate of expansion of the universe since the Big Bang. By studying the cosmic microwave background radiation, astronomers can determine the age of the universe to be about 13.8 billion years.
