All the planets are made of "matter" and that has "mass".
An inner planet is mostly made of iron and has more mass than outer planets, outer planets are mostly made of gasses, makeing them have less mass. The inner planets are the planets between the asteroid belt and the sun
It depends on the planet. Some planets, like Jupiter, are made from gas. While others, like Earth, are rocky planets.
All planets have mass.
Mass does not change with gravity. Weight increases on BIGGER planets and decreases on smaller planets.
Mass is an inherent property of matter and has nothing to do with sunlight. The planets are made of matter and therefore have mass.
A huge mass of stars and planets is called a galaxy.
Planets have gravity because they have mass.
There are eight planets. Pluto, formerly classed as a planet, has been reclassified and is now one of three dwarf planets.
Planets with a large amount of mass.
The solar system has three classified dwarf planets. They are Pluto, Ceres, and Eris. A dwarf planet has sufficient mass, has not cleared the neighborhood around its orbit, and is in orbit around a star.
Four planets, Jupiter, Saturn, Uranus, and Neptune, have mass greater than that of the Earth.
Mercury, with a mass of 0.055 times that of the Earth.Mercury is the smallest of the eight planets, and has the lowest mass.
