Planets are studied in the scientific discipline called astronomy. New discoveries in astronomy are being made nearly every day. According to astronomers, the planet of Pluto has been downgraded to an asteroid.

the inner planets are sometimes called Terrestrial Planets
Most asteroids are, not surprisingly called asteroid's. However some of the larger ones are refereed to as dwarf planets (Ceres) others planetoids or minor planets.
The Outer Planets are called Jovian Planets!
Actually Dwarf planets are planets which are very small in size and cannot be called planets but not as small to be called asteroids, so the name dwarf planets.
There is a branch of astronomy called planetary astronomy that takes geology and uses it to examine other planets, so yes rocks are studied in astronomy.

Seismology, which is a sub branch of geophysics.

Astronomy is the scientific study of the Universe: what is out there in space, how old the Universe is, what will be its future, etc. Astrology is a set of beliefs about mysterious influences the stars or planets have on us. This is not based on any scientific method, and is really just superstition. By the way, the people who study each of the discipline would be called "astronomers" and "astrologers"
A specific group of individuals, such as a sample population, is typically studied in a scientific poll to gather data and insights on a particular topic or issue. This group is chosen to be representative of the larger population, allowing researchers to draw conclusions that can be generalized.

A person who has studied physics is called a physicist.
Kepler studied the planets' orbits and published his three laws of planetary motion, in 1609 and 1619. His most famous work was probably the 1609 book called "Astronomia Nova".
They are sometimes called "major planets" to distinguish them from the "minor planets" (the asteroids) and "dwarf planets" like Pluto.
