Interesting Facts About Uranus

• The orbital speed of Uranus is 6.6 km/sec
• A year on Uranus is equal to 84.01 Earth Years
• Uranus is the third largest planet in the Solar System.
• Uranus is considered strange because the planet is tipped on its side. The poles in fact point towards the Sun. The reason behind this is that its magnetic field is tilted 60 degrees from the axis of rotation.
• Just like Venus, Uranus spins from east to west, which is opposite from the spin of Earth.
• A day on Venus is equal to .72 Earth Days
• Uranus maximum distance from the Sun is 3 billion km (1.88) billion miles
• Uranus minimum distance from the Earth is 2.6 billion km (1.6 billion miles)
• Diameter of Uranus is 51,488 km (32,000 miles)
• If you weigh 100 lbs on the Earth, your weight on Uranus would be 89 lbs.
• Summer on Uranus lasts one long day – 42 years
• Uranus is the second least dense planet of the Solar System
• Planet Uranus is so far away from the Sun, that the temperature difference between summer and winter at the poles is just 2°C (3.6°F).
• When observed from a telescope Uranus appears as a small, bluish-green disk with a faint green periphery.
• If compared to Earth, Uranus has a mass 14.5 times greater, it is 67 times bigger and gravity 1.17 times greater.
• The density of Uranus is about 1.2 times that of water.
• Planet Uranus is the coldest planet in the Solar System. However it is much closer than Neptune, which averages a distance of 4.5 billion km from the Sun. This is due to the fact that unlike other large planets in the Solar System, Uranus gives off less heat than it absorbs from the Sun. The other large planets have very hot cores and give out infrared radiation. However something made the core of Uranus cool down to the point because of that it doesn’t radiate much heat.
• Only one spacecraft in the history of spaceflight has ever come close to Uranus. NASA’s Voyager 2 in January, 1986, came within 81,000 km of the surface of Uranus. It captured thousands of photographs of Uranus and its moons and then sped off onto its next target: Neptune. No other spacecraft have ever been launched towards Uranus.
