Asteroid Comets are icy conglomerations of material, so cannot be called a "rocky object".
Of the 8 planets, four are rocky and four are gas planets, so there are equal numbers.
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)
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
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.
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.
Mercury is the closest planets to the sun, and is `rocky` so is also the closest rocky (or terrestrial) planet.
Well, honey, the inner planets are called terrestrial planets because they are rocky and solid, just like your ex's heart. They are closer to the sun and have similar characteristics to Earth, unlike those gas giants that are just full of hot air. So, basically, they are named that way because they are Earth-like, but without all the drama.
Gas planets are the planets formed with gas - eg earth has a crust so it is a rock planet. But Jupiter is a planet composed of gas so it is a gas planet. Nothing solid at all. The Gas Planets are: Jupiter Saturn Uranus Neptune
