The mass of the planet, the mass of the sun and the distance between the two.
No but the sizes of OTHER planets and planetesimals can and do.
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
yes, planets do orbit a star
No. The planets orbit the sun.
Kelper determined that the orbit of Mars orbit is not a circle but an ellipse.
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
No, orbits are strictly determined.
No but the sizes of OTHER planets and planetesimals can and do.
A planets year is the time it take to make one orbit of its star.
it is different because the size.
Planets orbit stars.
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
Its mainly due to their size, and the fact that Dwarf Planets have not cleared their orbit of enough of the other rocks and planetoids that are also at that orbit. Pluto has not cleared its orbit of enough matter to be deemed a major planet, while all of the remaining 8 planets have.
Planets or dwarf planets, depending on their size. (The larger ones would be planets, smaller would be dwarf planets.)
It depends on their size, mass, distance and strength of gravity.
The Sun has no moons. Moons orbit Planets > Planets orbit the Sun.
