our solar system
Our solar system is made up of the sun and its planetary system of eight planets, their moons and other non-stellar objects. Approximately 4.6 billion years ago it was created. Astronermers say that it was formed from a giant molecular cloud collapsing. The sun is the heaviest and definitely the largest planet out of the other eight. Mercury, Venus, Earth and Mars are the four smaller inner planets. The four smaller planets are also know as the terrestrial planets and the are composed of rock and metal. The outer planets are called the gas giants. These are much
bigger than the terrestrials. Jupiter and Saturn are the two largest and are made
largely of hydrogen and helium. Urnaus and Neptune are the two planets the furthest
away from the sun and another name for these two planets is ‘ice giants’, as they
are largely composed of ices, like water, ammonia and methane.
uranus
In the honour of King George III of England, Uranus was originally named ‘The Georgium Sidus’. In 1850 it was officially named ‘Uranus’ to keep with the tradition of naming planets after mythological Gods.
William Herschel was the man who discovered Uranus while he was searching the sky looking through a telescope. In the honour of King George III of England, Uranus was originally named ‘The Georgium Sidus’. In 1850 it was officially named ‘Uranus’ to keep with the tradition of naming planets after mythological Gods. Uranus is the third largest planet measuring 51120km in diameter and is the seventh planet from the sun. In a time span of 84 years it would have orbited around the sun once and takes 17.24 hours just to rotate. It gravitational pulls in 86% on Earth. Uranus is a gaseous planet and its atmosphere is 83% hydrogen, 15% helium and 2% methane. Uranus is the coldest planet in our solar system as its average temperature is -244°C.
Uranus rotates on an angle on about 90°, this could have been due to collision with a meteoroid. Because Uranus has a very strange angle, its season last about 21 years and each pole has constant sunlight for 42 years. Uranus’ core alone is the size our entire planet and the entire of Uranus is 14.5 times the size of Earth. Due to its extreme temperatures and harsh weather conditions Uranus is most likely impossible to live on.
