Uranus orbits the sun tilted on its side. This planet is composed mainly of the gases helium, hydrogen and methane. Its bluish-green color is due to the presence of methane.Know More
Scientists believe that Uranus's tilt, which is approximately 98 degrees, was caused by a collision with an object that was possibly as large as the Earth.
Discovered in 1781 by William Herschel, Uranus has 27 known moons and 13 rings. Some of its bigger moons are Titania, Oberon, Miranda and Ariel. The minimum temperature of this planet can be as low as -224.2 degrees Celsius. Its revolution period is 84 Earth years.
Uranus is the only planet that has a name derived from a Greek god instead of a Roman deity. The Greek god's name was Ouranus.Learn more about Planets
Earth is unique in that scientists have found the planet to be the only one to have liquid water on its surface, intelligent life forms living on it, a moon that helps regulate surface temperatures, an atmosphere with 21 percent oxygen and plate tectonics, according to Space.com. Scientists believe Earth exists in a "Goldilocks zone" where conditions are just right to support life.Full Answer >
According to Tim Sharp at Space.com, the planet Mars was formed in a similar fashion to every other planet in the Milky Way solar system. The formation occurred when a collection of gas and dust collapsed in on itself and pulled matter into the center of its gravitational force. This caused elements to clump into collections of planets. This is only scientists' present theory of planetary formation.Full Answer >
One year on Neptune is equal to around 165 Earth years or 60,190 Earth days, which is the amount of time it takes the planet to complete its orbit around the sun. Days on Neptune last about 16 hours, which is 8 hours less than Earth. This is the amount of time that it takes for Neptune to make a complete rotation on its axis.Full Answer >
There are no names for Mercury's moons because the planet does not have any moons. The only other planet that has no moons is Venus.Full Answer >
