Smallest gas planet found
WebbFacts about Neptune. Neptune is the most distant planet from the Sun. Neptune is the smallest gas giant. A year on Neptune lasts 165 Earth years. Neptune is named after the Roman god of the sea. Neptune has 6 faint rings. Neptune was not known to the ancients. It is not visible to the naked eye and was first observed in 1846. Webb21 maj 2024 · Gas dwarfs 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. A low-mass gas planet can still have a radius resembling that of a gas giant if it has the right temperature.

Webb21 mars 2024 · The 5,000-plus planets found so far include small, rocky worlds like Earth, gas giants many times larger than Jupiter, and “hot Jupiters” in scorchingly close orbits around their stars. There are “super-Earths,” which are possible rocky worlds bigger than our own, and “mini-Neptunes,” smaller versions of our system’s Neptune.

The term gas giant was coined in 1952 by the science fiction writer James Blish and was originally used to refer to all giant planets. It is, arguably, something of a misnomer because throughout most of the volume of all giant planets, the pressure is so high that matter is not in gaseous form. Other than solids in the … Visa mer A gas giant is a giant planet composed mainly of hydrogen and helium. Gas giants are also called failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System. … Visa mer Cold gas giants A cold hydrogen-rich gas giant more massive than Jupiter but less than about 500 MEarth (1.6 MJ) will only be slightly larger in volume than Jupiter. For masses above 500 MEarth, gravity will cause the planet to shrink (see Visa mer • List of gravitationally rounded objects of the Solar System • List of planet types • Hot Jupiter Visa mer Theoretically, gas giants can be divided into five distinct classes according to their modeled physical atmospheric properties, and hence their appearance: ammonia clouds (I), water clouds (II), cloudless (III), alkali-metal clouds (IV), and silicate clouds (V).
