Astronomy involves the study of stars, sun, moon, comets, planets, gas, galaxies, gas, dust and other non- earthly bodies. Therefore, the study of stars is known as astronomy.
Scientists that studies these non earthly bodies are called astronomers.
These scientists are also responsible for the discovery of the planets, stars, asteroids and other extraterrestrial objects.
The term astronomy has its origin in a Greek word known as “astron” which means stars.
Over the years, astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations.
