Size comparison of Earth and Uranus. Uranus's mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune's at roughly four times that of Earth. A resulting density of 1.27 g/cm 3 makes Uranus the second least dense planet, after Saturn.
It was believed that the cutoff for round objects is somewhere between 100 km and 200 km in radius if they have a large amount of ice in their makeup; [1] however, later studies revealed that icy satellites as large as Iapetus (1,470 kilometers in diameter) are not in hydrostatic equilibrium at this time, [2] and a 2019 assessment suggests that ...
The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
English: Comparison of angular diameter of the Sun, Moon and planets with the International Space Station (as seen from the surface of the Earth), the 20/20 row of the Snellen eye chart at the proper viewing distance and typical human visual acuity. The dotted circles represent the minimum angular size (when the celestial bodies are farthest ...

The radius of the Uranian Hill sphere is approximately 73 million km. [3] The relative sizes of moons are indicated by the size of their symbols, and the Caliban group of Uranian moons is labeled. Data as of February 2024. Uranus's irregular moons range in size from 120 to 200 km to under 10 km . [43]
