The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
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 ...
A type of exoplanet with a mass only a few times larger than Earth's but with a radius larger than that of Neptune, giving it a very low mean density. Kepler-51b, c and d: Silicate planet: A terrestrial planet that is composed primarily of silicate rocks. All four inner planets in the Solar System are silicon-based. Mercury, Venus, Earth and Mars
CAPE CANAVERAL, Fla. (AP) — Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The exoplanet has exceedingly low density for its size, an international team reported Tuesday. The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune — are much denser.

Astronomers say they have uncovered an unusual planet that’s about 50% bigger than Jupiter and somehow still the second lightest planet ever found.
A super-Jupiter is a gas giant exoplanet that is more massive than the planet Jupiter. For example, companions at the planet–brown dwarf borderline have been called super-Jupiters, such as around the star Kappa Andromedae. [1] By 2011 there were 180 known super-Jupiters, some hot, some cold. [2]
Beta Pictoris b is a super-Jupiter, an exoplanet that has a radius and mass greater than that of the planet Jupiter.It has a temperature of 1,724 K (1,451 °C; 2,644 °F), most likely due to its dusty atmosphere and mass (normally it would be much colder).
