The surface of Mercury is similar to the moons. Most of the craters peppering Mercury's surface were caused 3.7 or 4.5 billion years ago. The Great Bombardment was the time when craters were left on Mercury, earth's moon, and other surfaces in the universe. The craters on Mercury are flatter and have thinner rims than the ones on Earth. Bach and Mozart are examples of crater names. The Caloris Basin is the largest crater on Mercury. Its diameter is around 800 miles. Surrounding the Basin are the Caloris Mountains. These mountains were formed by piles of material were thrown out of the Basin. The weird terrain is almost opposite Caloris Basin. It consists of hills, ridges and grooves that cut across craters. The weird terrain my have been formed by shock waves that raced through the center of the planet and outward early in Mercury's history. A series of cliffs that are 100's of miles long run along Mercury's surface. These cliffs are called 'scarps'. The scarps were also probably formed early in the planets history. The surface is covered in a thin layer of dust in most areas. === === Young craters have sharp rims and bright rays extending outward. Others are degraded, with rims smoothed from crashing meteorites.

Mercury is the planet that most resembles the Moon in visible surface features and atmosphere. It is a grey planet that has many craters and a thin atmosphere.
Mercury, the Roman god of speed, is an appropriate name for the planet because it is the closest planet to the sun and moves rapidly in its orbit. Mercury's swift movement and short orbit period of just 88 days parallel the speedy characteristics associated with the god Mercury.
Mercury is the planet: there is no raw (or ripe) planet associated with it!
The Jovian planets are Jupiter, Saturn, Uranus, and Neptune. They share many characteristics including their location outside of the asteroid belt (between the orbits of Mars and Jupiter).
I dont know. planet earth is mistory
Hot
One of them is that is has a Greenhouse effect on it.
Mercury because some planet had to be
hot. I had it for my science project. "CAN YOU PLANET!"
Mercury has no atmosphere, is the closet to the sun, and has ice in some craters.

Mercury is a planet.
Mercury is not a dwarf planet. It is a planet.
Mercury is itself a planet - it did not come from a planet!
