How did Uranus get its name? Uranus is named after the ancient Greek god of the sky, who was the father of Kronos (Saturn in Roman mythology). Most of the other planets got their names thousands of years ago, but Uranus was discovered just a few hundred years ago – William Herschel found it on March 13, 1781
Like the rest of the planets in the Solar System, Uranus doesn’t have a perfectly circular orbit. Instead, it follows an elliptical path around the Sun. Astronomers call a planet’s closest approach to the Sun perihelion. The perihelion for Uranus is 2.75 billion km, or 18.4 astronomical units (1 AU is the distance from the Earth to the Sun). The most distant point of orbit is called aphelion. The aphelion of Uranus is 3.00 billion km, or 20 astronomical units. On average, Uranus orbits at a distance of 2.88 billion km, or 19.2 AU
Uranus data (averages):Diameter: 31,763 milesTime to rotate: 17 hours, 54 minutesOrbit: 84 Earth years
If you could stand on the surface of Uranus (you can’t, for so many reasons), you would experience 89% the force of gravity that you experience on Earth. Another way to look at it is that objects dropped towards Uranus will accelerate towards the planet at 8.69 m/s2.
Uranus orbits nearly on its side; its axis of rotation is skewed by 98 degrees relative to an ordinary upright orientation, perpendicular to the orbital plane. Many planetary scientists have sought to explain the odd tilt by invoking a giant impact into Uranus billions of years ago. But the giant planet has a system of moons circling its equator that would have been disrupted by such an impact
Uranus' atmosphere is made up of hydrogen, helium and methane. The methane in Uranus' upper atmosphere absorbs the red light from the Sun but reflects the blue light from the Sun back into space. This is why Uranus appears blue.also did U know the Uranus has 27 moons :D
