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 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]
With a mass 11.2% higher than that of Jupiter and a radius 11.4% greater, HD 189733 b orbits its host star once every 2.2 days at an orbital speed of 152.0 kilometers per second (152,000 meters per second; 340,000 miles per hour), making it a hot Jupiter with poor prospects for extraterrestrial life.
A light year is the distance light travels in a year, about 5.9 trillion miles (9.5 trillion km). ... only gas-giant planets larger than Jupiter, our solar system's biggest planet, had been ...
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 ...
Astronomers say they have uncovered an unusual planet that’s about 50% bigger than Jupiter and somehow still the second lightest planet ever found.
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 ...
Kepler-39b is a Jupiter-like planet or brown dwarf that is eighteen times more massive than Jupiter and 1.22 times Jupiter's size. For a planet of its size, Kepler-39b has a relatively cool equilibrium temperature of 905 K (632 °C; 1,169 °F) with respect to other inflated planets, defying most of the common models explaining inflation at the time of its discovery (including convection and ...
