Smallest gas giant discovered
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. 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 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 … Visa mer Jovian weather Heat that is funneled upward by local storms is a major driver of the weather on gas giants. Much, if not all, of the deep heat escaping the interior flows up through towering thunderstorms. These disturbances develop … Visa mer 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 … 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 WebbMercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter are the two smallest gas giants, in order of their size. It was difficult for Uranus and Neptune to collect hydrogen and helium as efficiently as Jupiter and Saturn because they were smaller and had larger orbits. This is most likely why they are smaller than the two planets.
