Planet Comparison- Uranus And Neptune
Planet Comparison Report
Uranus:
Uranus was discovered in 1781 by Sir William Herschel. He at first wanted to name the planet Sidus Georgium which is latin for Georges star after the king of England. Another astronomer Johann Bode advised Herschel against it and suggested instead that he use a name from Greco-Roman mythology like all other planets. So Uranus was given its name which is the father of Saturn.
Uranus is one of the Jovian planets and like the others it has a short rotation period. Uranuss day is 17.2 hours. Its revolution around the sun however is slightly more than 84 years. It is the seventh planet from the sun at a distance of 1.78 billion miles.
Uranus is about 4 times the diameter of earth at 46,700km. Its mass is 15 times that of earth at 8.68*10 kg. The axial tilt of this planet is one of the most unusual things about it. It is tilted 98 degrees which classifies it as being in retrograde rotation. Uranus is also unique because it has the most inclined magnetic field. The surface magnetic field is 74 percent that of the earth.
