Uranus: Everything you need to know about the coldest planet in the solar system

Uranus is the third largest planet in the solar system and the seventh planet from the sun. Due to Uranus' dimness and slow orbit, it was long mistaken for a star despite being visible to the unaided eye. Also notable is the planet's extreme tilt, which causes its axis to aim almost directly at the sun. William Herschel, a British astronomer, discovered Uranus on March 13, 1781, while using his telescope to survey all stars down to those approximately 10 times fainter than those visible to the unaided eye. #uranus #planet #universe #solarsystem
