The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
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).
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.

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.
Although Jupiter would need to be about 75 times more massive to fuse hydrogen and become a star, [68] its diameter is sufficient as the smallest red dwarf may be slightly larger in radius than Saturn. [69] Jupiter radiates more heat than it receives through solar radiation, due to the Kelvin–Helmholtz mechanism within its contracting interior.
Scientists have discovered a giant planet orbiting a massive pair of extremely hot stars, an environment previously thought too inhospitable for a planet to
