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 1.7 times the size of Jupiter.Some well-known planets that are smaller than 1.7 R J (19.055 R 🜨 or 121 536.4 km) have been included for the sake of comparison.
A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low-boiling point materials (), rather than rock or other solid matter, but massive solid planets can also exist.
The Solar System contains no known super-Earths, because Earth is the largest terrestrial planet in the Solar System, and all larger planets have both at least 14 times the mass of Earth and thick gaseous envelopes without well-defined rocky or watery surfaces; that is, they are either gas giants or ice giants, not terrestrial planets.
Two teams of scientists have discovered a theoretically habitable planet called Gliese 12b that’s smaller than Earth but bigger than Venus, just 40 light-years away.
Planets of mass similar to Uranus or Neptune; smaller than the gas giants, but still much larger than Earth. TOI-332b: Sub-Neptune: a planet with smaller radius than Neptune even though it may have a larger mass HD 110067 (b,c,d,e,f and g) Mini-Neptune: Also known as a gas dwarf or transitional planet. A planet up to 10 Earth masses, but less ...
By Irene Klotz BOSTON (Reuters) - Astronomers have discovered a new type of rocky planet beyond the solar system that weighs more than 17 times as much as Earth while being just over twice the ...
Scientists may have found Planet X -- the long-rumored object believed to be larger than Earth and further from the sun than Pluto. Planet X and another object dubbed "Planet Y," are among 13 ...
