The red planet, Mars.
Mars is the smallest of the three. (\_(\ (^_^) ('')_(")
There is not an exact count of the number of rocks on Mars, just as there is not an exact count of those on Earth. Mars is a rocky planet and many areas have been explored using rovers.
Mars has flat areas and rocky areas, just like Earth.
yes!! mercury is a rocky planet.lets just make this easier. i have recently learned that the first four planets are rocky and the last four are gaseous that makes mercury venus earth and mars rocky and Jupiter Saturn uranus and neptune gaseous. i have back up by my teachers and if you look up the question "which planets are rocky?" they have given the same answer.
None
Venus. It is just a bit smaller than Earth.
Venus is most nearly in size to the Earth, just slightly smaller.
Mercury is a rocky planet, just like all the terrestrial planets: Mercury, Venus, Earth and Mars.
No planet is the exact same size as the Earth but Venus is very close (it is just a little bit smaller) Mars is even smaller. See Link for a tour of planets and stars arranged by size.
The Earth is considered to be a big planet. In contrast, the Earth Venus is smaller then the Earth and Neptune is considered larger.

No. Earth is the largest of the terrestrial planets (of which there are four in the Solar system). Mars is the second smallest planet (Mercury is the smallest, and Venus is just a little smaller than Earth).
mars is smaller than the earth by quite a bit, but larger than the moon too. The planet's diameter is just over half that of the earth, at around 6800 km to the earth's 12700 km, and the its planetary mass is significantly smaller, measuring .65X10P24kg versus the earth's mass of 6X10P24kg.
Of the inner rocky planets, Mars is the second smallest, coming just a little bit smaller than Venus and Earth. When all eight planets are considered, Mars ranks seventh in size.
You could fit just under 18 of the planet mercury inside of the planet earth. Another way to say this would be: Mercury is 18 times smaller than earth.
The planet Venus is just slightly smaller than the Earth. It is larger than either Mars or Mercury, and it is much smaller than any of the four gas giants.
It has neither, it is just a rocky planet without an atmosphere
