If you mean all our planets and comets, it's called the Sun. It is called "The Solar System".

They are alike because they are both called planets, both terrestrial planets and gas giants are spheres, all have a somewhat dense core and lastly all orbit around the sun.
It is called the "ecliptic plane"
Those are called "Terrestrial Planets", which includes Mercury, Venus, Earth, and Mars.
The belt of constellations through which all the planets move is called zodiac. The true shape of the planetary orbits was discovered by Kepler.
They are sometimes called "major planets" to distinguish them from the "minor planets" (the asteroids) and "dwarf planets" like Pluto.
the inner planets are sometimes called Terrestrial Planets
