What is the difference between Astronomy and Cosmology and Astrophysics?

do cosmologists study the planets,stars etc. and phenomenon like gravitational force and others


what does an astronomer study and astrophysics deals with what?|||Cosmology refers to the universe as a whole - someone who studies the origin and evolution of the universe. It's not a degree - you could work in cosmology with a degree in astronomy, astrophysics, or physics. Astrophysics has a bit less astronomy and a bit more physics, astronomy has a bit less physics, but there's no clear line between them. Astronomers and astrophysicists study stars, planets, galaxies, etc.
