Resume de l’article : Une planète atypique dans le désert de Neptune

Article title: « Discovery of an atypical planet in the desert of Neptune »

The article discusses the discovery of an atypical exoplanet by a team of astronomers using data from the NASA Kepler mission. The planet, named TOI-2136 b, is located in the « desert of Neptune, » a region of the galaxy where there are few planets with masses similar to Neptune.

TOI-2136 b has a mass and radius that are intermediate between those of Neptune and Saturn, making it an unusual planet. It orbits its star at a distance that is closer than Mercury is to the Sun, but takes 11 Earth days to complete one orbit.

The planet’s density is similar to that of water, which is lower than that of any planet in our solar system. This suggests that TOI-2136 b may have a large gaseous envelope, but its composition and atmospheric properties remain unknown.

In summary, the key point of the article is the discovery of a unique exoplanet, TOI-2136 b, which is located in the « desert of Neptune » and has an intermediate mass and radius between Neptune and Saturn, with a low density and a short orbital period.
