I guess the closest planets in size are Earth and Venus
Your mass stays the same no matter where you are. Your weight will change.
Planets are larger and more massive than asteroids, but very nearly the same size and mass as planets.
No. The planets vary greatly in both size and mass.
an objects mass is always the same but the weight can change because on different planets, the gravitational pull is different. so, yes
All planets have mass.
Mass & distance.
All the planets are made of "matter" and that has "mass".
Mass does not change with gravity. Weight increases on BIGGER planets and decreases on smaller planets.
It is near Earth in size. About 81.5% of Earth's mass.
yes there is 2 planets but there are also dwarf ones too.
Uranus and Neptune are two outer planets that are similar in size. Both planets are known as ice giants and are similar in diameter and mass.
Quite simply, different planets have different masses. They are not all the same.
