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
Because weight is calculated based on gravitational pull, it is impractical to determine the weight of a planet. For example, an object weighing 500 pounds on Earth weighs 465 pounds on Saturn because of the planets' different gravitational pulls. Thus, planets are compared by calculating their mass, which remains constant.Full Answer >
The planet Neptune is incapable of supporting life as we know it, according to NASA. One major reason for this is because of the effective temperature, which is about minus 353 degrees Fahrenheit.Full Answer >
Objects near to Earth can move at a wide range of speeds, but the theoretical maximum velocity for anything on or around the planet is 11.2 kilometers per second. This upper limit is defined by the escape velocity of Earth. Anything moving above this threshold will be ejected to space.Full Answer >
No one knows who discovered Venus because the planet was known to the ancients. Named by the ancient Romans after their goddess of love and beauty, it is one of the brightest objects in the night sky.Full Answer >
