The smallest planet is Mercury, which is closest to the sun. Venus is the second from the sun. It is similar to Earth in size and mass, but it is so hot, that lead would melt on its surface. The third from the sun is Earth. Its distance from the sun allows it to have liquid water and an atmosphere suitable for life. The fourth from the sun is Mars.
