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 ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune ...
Jupiter is about ten times larger than Earth (11.209 R 🜨) and smaller than the Sun (0.102 76 R ☉). Jupiter's mass is 318 times that of Earth; [ 2 ] 2.5 times that of all the other planets in the Solar System combined.
This artist's visualisation of WASP-127b, a giant gas planet located about 520 light-years from Earth, shows its newly discovered supersonic jet winds that move around the planet's equator.
Of those objects that orbit the Sun directly, the largest eight are the planets (including Earth), with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.
Scientists have discovered a giant planet orbiting a massive pair of extremely hot stars, an environment previously thought too inhospitable for a planet to Mysterious planet 10 times bigger than ...
