Mercury has extreme temperature variations between 320°F and -116°F and the longest day lasts approximately 1407.5 hours. It is the closest planet to the sun at a distance of 150 million kilometres. Venus has a dense carbon dioxide atmosphere with sulfuric acid clouds and surface temperatures of 449°F. It rotates very slowly, taking 243 Earth days to complete a rotation. Earth has an atmosphere of oxygen, nitrogen, carbon dioxide and other gases and has a rotation period of 24 hours causing days and yearly revolution of 365 days. Mars has a thin carbon dioxide atmosphere with traces of oxygen, similar day and year lengths to Earth, and average temperatures of -25°F.
