What is the most common type of rock on Uranus?

Due to limited data and knowledge of Uranus's composition, the most common type of rock on Uranus is still a topic of research and speculation. Uranus is an ice giant, and it is believed to consist primarily of hydrogen and helium, along with other elements such as methane and ammonia. These elements exist in the form of an ice layer, which is theorized to surround a rock and metal core. The exact composition of Uranus's core is still unknown.

Although scientists have yet to determine the most common type of rock on Uranus, they have been able to make observations and measurements of its atmosphere and magnetic field. The atmosphere of Uranus is composed mostly of hydrogen and helium, with small amounts of methane and other gases. The magnetic field of Uranus is tilted at an angle of 60 degrees from its axis of rotation, which is also believed to be responsible for its unique characteristics such as its extreme seasonal changes and odd magnetic field.
