Americans astronomers they discovered a giant exoplanet that is made up mostly of gases and has density of one candy marshmallow.

it’s about him TOI-3757bJupiter-sized and located 580 light-years from Earth in the constellation Genioch.

This particular planet is in orbit around one red dwarf. Red dwarfs are the smallest and faintest M-type stars, cooler than stars like our Sun, but which can be very active and capable of powerful bursts of “ripping” radiation. nearby planets from their atmospheres. The formation of gas giant exoplanets around such stars is considered difficult.

Thus, TOI-3757b is a planet with smallest and fluffiest density what has ever been discovered around such a star.

The researchers, led by Suban Kanodia of the Carnegie Institution of Science, made a corresponding publication in the journal Astrophysics. “Astrophysical Journal”reported that it remains a mystery how a low-dense planet like TOI-3757b could form around a red dwarf.

Specifications TOI-3757b

It is believed that the considered exoplanet has a large rocky core (perhaps with a mass ten times the mass of the Earth), around which a large amount of gases has accumulated. Its diameter is estimated to be around 150,000 kilometers, slightly larger than that of Jupiter.

The planet completes an orbit around its parent star in just 3.5 days (length of its year).

Its mass is estimated at about a quarter Per or about 85 times more than on Earth.

Its average density was only 0.27 grams per cubic centimeter, which is less than half that of Saturn (the planet with the lowest density in our solar system), or about a quarter of the density of water or similar in density to a marshmallow-type confection.

In other words, the planet he will swim comfortably in a huge space … bath.

The initial detection of the planet was made by NASA’s TESS space telescope, followed by further observations with various ground-based telescopes. More observations to follow with the Large Space Telescope James Webb.
