Record discovered a small exoplanet


L 98-59b — has a diameter of about 80% of the earth.

L 98-59 — red dwarf, unremarkable, but promising great opportunities for planetary scientists. Discovered exoplanets are out of the area in which on their surface may exist liquid water.

This writes the with reference to

Probably they receive from their stars about the same energy as Venus is from the Sun, but it is too early to talk about what conditions they can be similar to Venus.

One of them — L 98-59b — has a diameter of about 80% of the earth, making it the smallest exoplanet, discovered TESS so far. Kepler, however, found objects and smaller, so we are now talking about the “personal record” of a particular telescope.
Two other world in the system L 98-L and 98 59c-59d, respectively, about 1.4 and 1.6 times bigger than Earth.

L 98-59b, the closest to the star world, makes one revolution around it in just 2.25 earthly days, and receives from the star is 22 times more energy than earth is from the Sun. Average planet L 98-59c, is drawn with a frequency of 3.7 days and gets 11 times more radiation than the Earth.

L 98-59d, the most distant planet, is identified for the moment, the year is 7.5 days. It receives from the sun is four times more energy than the Earth. Scientists believe that the conditions can somewhat like Neptune, just much hotter — it seems that there is a powerful atmosphere, the composition of which is still not known.

Astronomers plan to continue monitoring the system to understand whether there is something else interesting.
