Planets do not technically need their respective stars, but stars keep planets in orbit and provide heat and light to the planets.
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
An Astronomer is a scientist who studies the stars and planets.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
Stars do, by their own power. Planets merely reflect light.
No. Stars are their own class of of objects. In simple terms planets orbit stars and moons orbit planets.
Planets orbit stars.
stars, the planets have to get heat from stars

Planets and stars have gravity.
The Solar System Makes the planets and the Stars.
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.

Astronomers (and their ilk) study stars and planets.
No. Stars are like suns, around which planets may orbit.
None Stars are gas Planets are solid
Planets orbit the sun. Stars do not.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
