turns backwards on it's axis
225 Earth days is a year for Venus, it takes 243 Earth days for one day to pass on Venus
Radius is 6.052 km (95% size of Earth)
Volume is 86% of Earth
Mass is 4.87 x 10^ 24 kg (82% mass of Earth)
90% gravity of Earth
Surface temperature is 462 C, hot enough to melt lead
Often called Earth's twin for being so similar to the planet
Much fewer craters then other planets, 300-500 million years ago an event erased all present craters at that time
Smooth volcanic plains, many extinct volcanic peaks and impact craters
No moons, No rings]]> 2019-12-11 16:51:10 UTC https://padlet.com/55868/oom372waw75i/wish/422830297 55868 https://padlet.com/55868/oom372waw75i/wish/422841461 Crust- 10 to 50 kilometers thick crush, made up of silicate rock
Mantel- thought to be 3,000 km thick, composition is unknown
Core- 2,900 km radius, external core made of liquid iron and Nickle, internal core made of solid iron and Nickle
Earth and Venus have a similar internal structure but scientist are not certain about this
Average density is 5.25g/cm3

3.5% of Nitrogen
Trace amounts of other gases, sulfur dioxide, water vapor
No water on the surface of the planet
Atmosphere Pressure is 92 times that of Earth
Greenhouse gases boiled away all water that might have once been there
Lack of magnetic field
Hydrogen blown away by solar flares from the Sun
Has no way to cool down

Spacecrafts have landed on Venus, such as Venera 13 which took colored pictured
Spacecrafts sent to orbit around the planet using radar to study it
Analyzing infrared radiation that comes from the planet is another way we have learned about the planet
Some scientist  that worked on Venus are Carl Sagan, Galileo,  and others]]> 2019-12-11 17:28:19 UTC https://padlet.com/55868/oom372waw75i/wish/422855566
