The size of solid bodies does not include an object's atmosphere. For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [11]
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.
The planet is located some 1,200 light-years away. A light-year is 5.8 trillion miles. It's the second-lightest exoplanet found so far based on its dimensions and mass, according to the ...
The planet is slightly less massive than Jupiter (0.919 ± 0.073 M J) but its diameter is 84% larger. This give TrES-4 an average density of only about a third of a gram per cubic centimetre, approximately the same as Saturn's moon Methone. At the time of its discovery in 2007, TrES-4 was both the largest-known planet and the planet with the ...
Although more massive than Jupiter, Tyche would be about Jupiter's size since degenerate pressure causes massive gas giants to increase only in density, not in size, relative to their mass. [ a ] If Tyche was to be found, it was expected to be found by the end of 2013 and only be 1–2 Jupiter masses.
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 ...
It is slightly larger than Jupiter, around 8%. The angular separation of the planet from its parent star is about 2.5 arcseconds, corresponding to a projected separation of 44.7 AU, [2] which is nearly nine times the distance between Jupiter and the Sun, which poses a challenge to theoretical ideas of how giant planets form.

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). It has a mass of between 9 and 13 Jupiter masses (M J), [5] and a radius of 1.46 R J. [2]
