It was once expected that any icy body larger than approximately 200 km in radius was likely to be in hydrostatic equilibrium (HE). [7] However, Ceres (r = 470 km) is the smallest body for which detailed measurements are consistent with hydrostatic equilibrium, [ 8 ] whereas Iapetus (r = 735 km) is the largest icy body that has been found to ...
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.
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).
A planet that is more massive than the planet Neptune. These planets are generally described as being around 5–7 times as large as Earth with estimated masses of 20–80 M E; PH1b, K2-33b: Neptunian planet: Planets of mass similar to Uranus or Neptune; smaller than the gas giants, but still much larger than Earth. Gliese 436 b, GJ 3470 b: Sub ...
By RYAN GORMAN Scientists may have found Planet X -- the long-rumored object believed to be larger than Earth and further from the sun than Pluto. Planet X and another object dubbed "Planet Y ...
4.6 km on north face, 3.6 km on south face; [n 4] highest elevation (8.8 km) above sea level, as well as by wet and dry prominence (but not among the tallest from base to peak, and in distance to Earth's center Mt Chimborazo rises highest).

The planet, called LHS 3154 b, orbits at about 2.3% of Earth's orbital distance from the sun, circling its star every 3.7 days. It is much closer even than our solar system's innermost planet ...
