Mercury, Venus, Earth and Mars are the Rocky planets. They are called so simply because they are rocky, their outer layer is solid. All other planets in the solar system are gaseous.
Asteroid Comets are icy conglomerations of material, so cannot be called a "rocky object".
Gas planets have mor planets then rocky planets because rocky planets are like earth. Gas planets are just difrent in there own way. If im wrong tell me but im pretty sure that's why. they are larger so the gravity captures more satalites
Of the 8 planets, four are rocky and four are gas planets, so there are equal numbers.
Mercury is the closest planets to the sun, and is `rocky` so is also the closest rocky (or terrestrial) planet.
Please tell me you mean Planets not Plants, that is an odd image. Rocky Planets are made mostly of Rock ie solid stuff. Gas Giants are made mostly of Gas. Most gas giants are much bigger than the rocky planets. So far most of the extra solar planets are gas giants (they are bigger so easier to find)
THEY ARE SMALL AND HAVE ROCKY SURFACESThey have a rocky surface, also known as terrestrial planets.They are rocky in their composition.They are roughly similar in size and density, and are all closer to the sun than the gas planets.
The Earth is an inner planet, and all the inner planets are rocky. The Moon is made out of the same matter as the Earth, so yes, they are both rocky spheres.
The four inner, rocky planets are also known as the terrestrial planets, since they have a clearly defined terrain (unlike the four outer gas giant planets). The terms are derived from Latin words for Earth (Terra and Tellus), so these planets are, in a certain way, "Earth-like".
Yes, there could be life on other rocky planets. We haven't found any so far, but it could be there.
Mainly, they are closer to the Sun, hence the name. Also they are smaller and therefore have much thinner atmospheres, so they show their rocky exteriors, hence they are known as the rocky planets.
Mercury is the closest of the eight planets to the sun.
Actually Dwarf planets are planets which are very small in size and cannot be called planets but not as small to be called asteroids, so the name dwarf planets.
