Saturn's beautiful ring is composed of numerous small objects, they rotate around the Saturn in Saturn's equatorial plane. The picture shows the Voyager Ⅱ four million kilometers from Saturn's rings taken local photos

Venus has very thick carbon dioxide Atmosphere, No water. It clouds composed of sulfuric acid droplets . Venus's thick atmosphere of carbon dioxide caused by the powerful "greenhouse effect“. Surface temperatures up to 460℃
Solar System Profile
Mercury
Equatorial radius 2439km Rotation period 58.65 days Period of revolution 87.97 days
Mercury Surface is not a drop of water. The highest temperatures of up to 350℃ . The minimum temperature is only -170℃. Any Life can not survive
Venus
Equatorial radius 6051km Rotation period 243.01 days Period of revolution 224.7 days
Venus's rotation is very special , Rotation direction contrary to other planets , It is from east to west , Therefore , Venus point of view, the sun rise from west and sundown in east . Venus has a rotation period of 243 days. Orbital period of 224.7 days. So a "day" on Venus is longer than "years".
