Uranus may not have any geologic activity for scientists to study, but some of its moons do. As far as astronomers know in 2014, Uranus has 27 moons, and five of them are large enough to have been discovered from Earth using telescopes. The other 22 were discovered by Voyager and the Hubble Space Telescope.Apr 25, 2017
Does Uranus have geographical features?
Scientists report that between 80 percent and 85 percent of Uranus consist if an ice and rock mass. The ices are mostly frozen water, ammonia and methane around a liquid core. An envelope of hydrogen and helium, with traces of methane and ammonia, forms the planets' atmosphere.
What planets have geological activity?
The geology of solar terrestrial planets mainly deals with the geological aspects of the four terrestrial planets of the Solar System – Mercury, Venus, Earth, and Mars – and one terrestrial dwarf planet: Ceres. Earth is the only terrestrial planet known to have an active hydrosphere.
What are the geological features of Uranus?
Uranus is made of water, methane, and ammonia fluids above a small rocky center. Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue. Uranus also has faint rings.
Is there seismic activity on Uranus?
Earthquakes appear to occur more frequently when Saturn and Uranus are strong. This theory is based on limited observation and this formula is an attempt to get an objective measure of each quake.
Why Uranus has an unusual orbit?
Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed.

Which planet is least geologically active?
Mars Aside from Mercury, our nearest neighbor planets are Venus, which is shrouded in cloaking greenhouse gasses that make it extremely difficult to observe the surface, and Mars, which has long been thought to be at least mostly geologically dead.
Is Jupiter geologically active?
The strong gravitational pull of Jupiter causes Io to be geologically active, and it's thought to be the most geologically active object in the Solar System, with over 500 volcanic centres and over 100 mountains, some almost twice the height of Everest.
Is Uranus mostly gas or rock?
Uranus is an ice giant (instead of a gas giant). It is mostly made of flowing icy materials above a solid core.
