The question is not well-defined enough to answer.
One common division is between "terrestrial" (rocky) planets and "jovian" (gas giant) planets. Some people make a distinction between "gas giants" (Jupiter and Neptune) and "ice giants" (Uranus and Neptune).
Rocky planets and gaseous planets.
Many kinds. their are Lander that crash into planets, orbiters orbit planets, rovers move and study the planet, and deep space probe fly away to study the Universe.
the inner planets are made of rock, ice and other materials while the outer planets are made of different kinds of gases except for pluto.
Astronomy, Glaciology, exo-planets.
They are mostly different kinds of gas.
it give us the info about the differnt info about planets and kinds of it
"solar system" is the term used to describe planets orbiting a star. We know that planets also orbit binary and tertiary star systems, these would be different kinds of solar systems.

In the solar system, we have a star, planets, dwarf planets, asteroids, comets, meteors, and human debris. (such as old satellites, probes, etc.)
