13 avr. 2022 · The coolest of the new planets is another sub-Saturn, K2-387 b, with an estimated temperature of 152 degrees Fahrenheit (67 Celsius). K2 384, a new system of five planets ranging from around the size of Earth to “mini-Neptune” sized, in some ways resembles the now-famous TRAPPIST-1 system – seven Earth-sized planets orbiting a ...
K2-387 b is a gas giant exoplanet that orbits an M-type star. Its mass is 0.133 Jupiters and it takes 28.7 days to complete one orbit of its star. Its discovery was announced in 2022.
23 juin 2021 · Here we report that 1,715 stars within 100 parsecs from the Sun are in the right position to have spotted life on a transiting Earth since early human civilization (about 5,000 years ago), with...
Habitable zone. The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). This is only an estimate, using the star's spectral type and mass.

20 juil. 2016 · K2–72 is an M dwarf star orbited by four planets, lying in the direction of the Aquarius constellation. Researchers suggest all four of these worlds could be rocky, and while they orbit their host star very closely, K2–72's relative coolness means two of them might be habitable.
3 mars 2022 · Here we present the results of an ongoing project to follow-up and statistically validate new K2 planets, in particular to identify promising new targets for further characterization.
