Red dwarfs have been found to be the most common type of star in our galaxy. These stars have a lower temperature and brightness than the Sun, so their habitable zone is closer to them than the habitable zone of stars like the Sun or naturally larger and hotter or brighter than the Sun.

It has also been found that red dwarfs host more planets on average than other types of stars in the Universe. A research team led by scientists from the famous Caltech University in the USA have discovered a new exoplanet orbiting a red dwarf and have started publishing it in scientific online databases and journals.

The exoplanet belongs to the TOI-5205 star system located 283 light years from Earth. This star is estimated to have about 60% less mass than that of the Sun. It is a gas giant only one time larger than Jupiter, the largest planet in our solar system. It is one of the largest planets discovered to date in a red dwarf system. The researchers have collected data that their study is expected to provide clues about the composition of the exoplanet and its atmospheric evolution.
