A planet that is more massive than the planet Neptune. These planets are generally described as being around 5–7 times as large as Earth with estimated masses of 20–80 M E; PH1b, K2-33b: Neptunian planet: Planets of mass similar to Uranus or Neptune; smaller than the gas giants, but still much larger than Earth. Gliese 436 b, GJ 3470 b: Sub ...
The smallest known extrasolar planet that is likely a "gas planet" is Kepler-138d, which has the same mass as Earth but is 60% larger and therefore has a density that indicates a thick gas envelope. [16] A low-mass gas planet can still have a radius resembling that of a gas giant if it has the right temperature. [17]
After a planet reaches a mass somewhat larger than Mars's mass, it begins to accumulate an extended atmosphere, [7] greatly increasing the capture rate of the planetesimals by means of atmospheric drag. [8] [9] Depending on the accretion history of solids and gas, a giant planet, an ice giant, or a terrestrial planet may result.
The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune — are much denser. “The planet is basically super fluffy” because it's made mostly of light gases rather than ...
A planet is any object in orbit around the Sun with a diameter greater than 2,000 km. (Eleven votes in favor) A planet is any object in orbit around the Sun whose shape is stable due to its own gravity. (Eight votes in favor) A planet is any object in orbit around the Sun that is dominant in its immediate neighbourhood. (Six votes in favor) [48 ...
It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth , and a tenth that of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm ), with an orbital period of 11.86 years .
Desert planet: A terrestrial planet with little to no water. Extragalactic planet: A planet that is located outside the Milky Way galaxy Eyeball planet: A tidally locked planet where uneven heating of the surface induces spatial features resembling a human eye. Helium planet: A gas giant composed mainly of helium instead of hydrogen. Hycean ...
The planet appears as a small and "full" disc when it is on the opposite side of the Sun (at superior conjunction). Venus shows a larger disc and "quarter phase" at its maximum elongations from the Sun, and appears at its brightest in the night sky. The planet presents a much larger thin "crescent" in telescopic views as it passes along the ...
