Fact: General facts about Venus
Venus is the second planet away from the sun and looks hazy yellow from the outside. Although it has very dense clouds and atmosphere it can be hotter than the airless Mercury which is even closer to the sun. Between the heat and corrosive air, Venus has been a very difficult planet to study using probes or instruments designed to land on the surface.
Facts About Mercury
Name Origin: Roman. Venus was named by the ancient Romans, who named the planet after the goddess of love and beauty. It is so bright in the night time sky it shines brighter than even the brightest stars.
Size: Average Diameter of 12,000km, Mass of approximately 4.8 x 10^24 Kg. Venus is just slightly smaller in size than the Earth, both in diameter and how heavy it is. Of all the planets in our solar system, it is the planet closest in size to Earth.
Gravity: 0.9g. As a result of its very similar size, the gravity on Venus is only slightly less than on Earth. If you weighed 150lbs on Earth, you would weigh 135lbs on Venus!
Temperature: Venus averages 462 degrees C at the surface making it the hottest planet in the solar system. This is due less to the close orbit to the sun and more due to the very thick atmosphere causing a greenhouse effect!
Days: Rotational period 243 days. Although nearly the same size as the earth Venus rotates very slowly. A single day lasts about 8 months on Venus. It also is spins in the opposite direction!
Orbit: Semi Major Axis: 108.2 million km, Orbital Period 224.9 days. Because it is closer to the sun Venus travels around it more quickly than the earth. A year on Venus takes only 7 months!
Atmosphere: Carbon Dioxide, Nitrogen. Venus has an amazingly thick atmosphere. At the surface it is more than 50 times as dense as found at sea level on Earth, and has so much pressure it would be the same a being more than 1 kilometer under water in an Earth ocean!
Surface structures: Most of the surface of Venus is covered by clouds too thick to see through, however research from space probes suggests that Venus is mostly covered in large plains (or basins) and only has 2 ‘continents’.
Fun facts: Venus is the brightest object visible in the nighttime sky, aside from the Moon. It was often called the “Evening Star” because it is most commonly seen around the times of Sunset and Sunrise. It is so bright that it has often been mistaken for a flying craft, making Venus the most common sightings of UFOs!
