Asteroids. Most asteroids lie between the orbits of Mars and Jupiter.
The journey a planet makes around the sun is called its orbit.
This is called "orbit".
That is called the planet's orbit.
U answer
The path that the planet follows is simply called the orbit. Orbit can mean 'to revolve around the sun' or it can be referred to as the path itself, e.g. 'Earth is following its orbit.'
An orbit.
Planets orbit stars. Our planet (earth) orbits a star we call the sun.
Orbit
Neither. Except perhaps in a poetic sense. Planets orbit around the sun. Moons orbit around planets. The earth has only one and we call it "the moon".
orbit
We call that path the "orbit" of the orbiting body. Note: You would not ever see a planet orbiting another planet. At least, if you did, you would not call them both planets.
A planet that orbits a star is called an exoplanet.
