The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. Although much smaller and not as massive as the outer gas giant planets, they are more dense.
The planets travel around the sun.
The sun is made from hot gases, collected by gravity, in a way so dense, it burns, and planets are either gases or rock, but not dense enough to burn.

The planets orbit (travel) around the Sun.
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.
Terestrial planets Mercury, Venus, Earth and mars.
Terestrial planets
the planets go around in circles around the sun
Planets circle in an elliptical orbit around the Sun.
The planets closer to the sun tend to have rocky crust and dense cores.
The planets are satellites of the sun. The moons are satellites of the planets. The moons revolve around the planets captured by their gravity, while the planets revolve around the sun captured by its gravity and the sun.
The four planets closest to the Sun all have rocky crusts and dense cores. These planets are Mercury, Venus, Earth, and Mars.
