Conservation of rotational momentum around the common center of mass.
The gas/dust cloud that formed the solar system was rotating and that momentum is conserved in the orbits of the planets, comets, asteroids, etc.
No, they orbit around the Sun. The planets and the Sun are all in our solar system.
the orbit of planets around the Sun in the Solar systemthe orbit of moons around their planets in the Solar system
the orbit of planets around the Sun in the Solar systemthe orbit of moons around their planets in the Solar system
Extra solar (or Exo) planets are planets that do not orbit the Sun. Planets in our solar system orbit the Sun.
Extra solar (or Exo) planets are planets that do not orbit the Sun. Planets in our solar system orbit the Sun.
The planets orbit the Sun. The Sun is at the center of our solar system and does not move.
gravity
The closer planets are to the Sun the faster their orbit speed
All of the planets in our solar system have an elliptical orbit around the sun.
All the planets in OUR solar system orbit around the sun(which is a star). Planets in other solar systems orbit around other stars.
This is because the planets do not orbit the moon they orbit the sun
Orbit the Sun.
