Smallest gas giant discovered
In 1952, science fiction writer James Blish coined the term gas giant and it was used to refer to the large non-terrestrial planets of the Solar System. However, since the late 1940s the compositions of Uranus and Neptune have been understood to be significantly different from those of Jupiter and Saturn. They are primarily composed of elements heavier than hydrogen and helium, constituting a separate type of giant planet altogether. Because during their formation Uranus and Neptune inco… WebbThe planet, named TOI-3757 b, is the fluffiest gas giant planet ever discovered around this type of star.

Webb25 apr. 2024 · Although it has the most spectacular ring system in the solar system, Saturn is not the only planet that has rings. Interestingly, each of the four gas giants has rings. Jupiter, Saturn, Uranus, and Neptune each possess their own ring system. Even the Earth had a small ring system in the distant past, and Mars may be getting one in the far future. Webb24 okt. 2024 · There are several aspects to TOI-3757 b that are mysterious, including how a gas giant star can form in orbit around a red dwarf star. The researchers believe that the rocky core of the gas giant formed more slowly than other similar exoplanets, leading to a more gradual accumulation of the gas under the influence of the gravity of the protoplanet.

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.
