The intensity of sunlight varies inversely with the square of the distance—on Uranus (at about 20 times the distance from the Sun compared to Earth), it is about 1/400 the intensity of light on Earth. [71] The orbital elements of Uranus were first calculated in 1783 by Pierre-Simon Laplace. [72]
The angles for Earth, Uranus, and Venus are approximately 23°, 97°, and 177° respectively. In astronomy , axial tilt , also known as obliquity , is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane ; equivalently, it is the angle between its equatorial plane and orbital ...
Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years. The length of a day on Uranus as measured by Voyager 2 is 17 hours and 14 minutes. Uranus is distinguished by the fact that it is tipped on ...
The probes, which continue to travel billions of miles away, have both reached interstellar space – Voyager 1 in 2012 and Voyager 2 in 2018, according to NA S A.
Miranda, also designated Uranus V, is the smallest and innermost of Uranus's five round satellites. It was discovered by Gerard Kuiper on 16 February 1948 at McDonald Observatory in Texas , and named after Miranda from William Shakespeare 's play The Tempest . [ 9 ]
Uranus, blue-green in color due to the methane contained in an atmosphere comprised mostly of hydrogen and helium, has a diameter of about 31,500 miles (50,700 km). It is big enough to fit 63 ...
Oberon orbits Uranus at a distance of about 584,000 km, being the farthest from the planet among its five major moons. [e] Oberon's orbit has a small orbital eccentricity and inclination relative to the equator of Uranus. [4] Its orbital period is around 13.5 days, coincident with its rotational period.
Umbriel orbits Uranus at the distance of about 266,000 km (165,000 mi), being the third farthest from the planet among its five major moons. [ e ] Umbriel's orbit has a small eccentricity and is inclined very little relative to the equator of Uranus. [ 2 ]
