Mercury is the smallest of the eight planets, and is the only one not to have an atmosphere. This is due to its small size and close proximity to the sun.
Venus is roughly the same size as Earth and has its own thick atmosphere composed mainly of carbon dioxide. This atmosphere creates a strong greenhouse effect, leading to extremely high surface temperatures on Venus.
