This is the first and nearest planet to the sun, Mercury. The planet is slightly larger than our moon. On the surface of the moon is covered with craters just like the moon but since it is so near to the sun, the side that is facing the sun is extremely hot. The temperatures can reach to about 800o F.
Mercury has a very weak atmosphere. It has a tiny amount of helium 1000 KM above the surface which was caused by the break down of Mercury's crust. But these elements can be lost when react with the sun.
Since Mercury is just slightly bigger than our moon, it does not have any rings or moons.
