Uranus



Uranus
    Before the invention of the telescope, man can only try to see planets like Mercury, Venus, Mars, Jupiter and Saturn with their naked eye . In 1781 Uranus was discovered by a British astronomer, William Herschel using a telescope he made himself . This discovery motivated people at that time to look for other planets .
    The diameter of Uranus is 51118 km and is the third largest planet in the Solar System . It takes 84 years to orbit the Sun and 24 hours to rotates on its own axis . The thick atmosphere in Uranus causes it to look bluish-green .
    One thing that is special about Uranus is that it rotates on its side and this cause it look like it is reclining ( resting in a horizontal position ) while rotating about its own axis .
