Venus is the second planet from the Sun. Exactly, it is 108,208,927 kilometers from the Sun. Venus is a planet much similar to Earth. Some may even call her Earth's evil twin! This being because of her dense, dry atmosphere, if you were to live on her, you would die. She can't support life do to the lack of an ozone layer. Venus's atmosphere also is made of about 97% carbon dioxide and about 3% nitrogen. Because of this thick atmosphere it gives Venus a greenhouse effect. Where the planet is so hot any probes we send will usually not last that long. Venus is also called Earth's evil twin because of the similarity in size. Venus's mass is 4.87x10^24 kg and its diameter is 12,100 km. Venus also has iron core like Earth. It is about 6000 km in diameter. Not only does Venus have an iron core it also has a molten, rocky mantle.

Check out these cool otherworld fun facts!
On Venus we have MUCH shorter distances between birthdays:
  • Jacquelyne Zahner's next B-Day on Venus is on Sunday July 11th, 2010, and she will be turning 22 years and 20 days old!
  • Emily Weaver's next B-Day on Venus is on Saturday January 30th, 2010, and she will be turning 22.8 years and 21 days old!
  • Cassie Smith's next B-Day on Venus is on Wednesday June 30, 2010 and she will be turning 22.1 years and 20.4 days old!
  • HAPPY B-DAY TO US!!!!!!!!!!

We also weigh a LOT less than we do on Earth:
  • A 110 pound person weighs 99.7 pounds
  • A 170 pound person weighs 154.1 pounds

If the sun were 615 milimeters in a scale model...
  • Venus would be approximatly 12,106 km., .2105 In., and 5.3mm in size!

Several probes have visited this evil twin including, *drum-role* the Venera probes!
Pioneer Venus and Soviet Venera 7 were the first spacecraft to actually land ON another planet! Of course these probes didn't last long because of the sulfuric acid found on Venus.
Venera 9 returned the first photographs of the surface!


The planet Venus has a very long day. Its day is 116 Earth days long! Venus's day is about half as long as its year. The year on Venus is about 225 Earth days long! Venus is a the hottest of all planets. Its average temperature is 864 degrees fahrenheit(462 degrees celsius)!!! Venus also has a density of 5.204 g/cm^3. The escape velocity on this planet is 31,000 km/hr.

Fun Facts about Venus!

Ishtar Terra - Ishtar terra is a highland area in one of Venus's four mountain ranges. This land is marked by unique deformities called tessera.
Aphrodite Terra - Aphrodite Terra is another highland about the size of South America which is located along the equater.
Sapas Mons and Gula Mons - These are both large volcanoes on the surface of Venus.
Maxwell Montes - Maxwell Montes are the highest mountains on Venus. The highest peak is 6.8 mi(11 km). A 65 mi(105 km) diameter depression called the Cleopatra Crater is one of the range's largest features.
Lakshmi Planum - Lakshmi Planum is a plateau terrain on Venus that has flat land with sudden, deep slopes around it.
Dense Atmosphere and Clouds - The atmosphere overheats the planet and causes the greenhouse effect and the clouds on Venus creates acid rain that evaporates before it hits the ground.

Expeditions of our evil twin!

  • Mariner 2 was the first probe to EVER visit Venus. This mission, in 1962, was unsuccessful
  • Several other missions were made, exactly 20, and Venus's surface was gradually seen.
  • In the meantime,U.S. spacecraft Magellan was put into place... this orbiter produced many useful detailed maps of Venus's surface by radar.
  • Before this occurred though, Venera 9 returned the first photographs/ mapped 98% of Venus's surface. This was the first spacecraft to land on another planet.
  • Venera 9 was the first probe to return data from the surface of another planet.
  • 1990-1994 NASA Magellan radar mapping mission discovered a small magnetic field on Venus.
  • Currently ESA's Venus Express is in orbit with large varieties of instruments.
  • Other current missions for the following 20 years are listed on this site:external image xin_38211042916588753249023.jpg
