They orbit around the sun.
They're not.
all planets.
Mercury doesn't "have planets".
yes there is 2 planets but there are also dwarf ones too.
Do all planets and satellites lie on the same gravitational layer?
No two planets share the same moon.
They're not.
all planets.
they are the same
The planets of our solar system are most definitely NOT all the same size.
Mercury doesn't "have planets".
there are no inner gas planets only outer gas planets but they are the same because they all have rings, they are all made of gas.
yes there is 2 planets but there are also dwarf ones too.
Because their distances are not the same from the Sun. Minus this factor, it is impossible for any planets to orbit on the same orbitation.
Planets are larger and more massive than asteroids, but very nearly the same size and mass as planets.
yes because they are nearly the same size and same colour so they are twin planets
Do all planets and satellites lie on the same gravitational layer?
