(ORDO NEWS) — LHS 1140 b is a massive, rocky exoplanet orbiting a very small and surprisingly calm red dwarf in the habitable zone.
The mass of LHS 1140 b is 7 times the mass of the Earth, which means that the exoplanet is a representative of the “Super-Earth” class.
LHS 1140 b is 40 light-years from Earth, making it easy to study with ground-based and/or space-based telescopes.
The radius of the parent star is 0.186 of the radius and 0.146 of the mass of our star. At the same time, no powerful flares from the side of the star have ever been recorded.
A year on LHS 1140 b is 24.7 days long. Without taking into account the greenhouse effect, the average temperature on the exoplanet’s surface drops to -43 degrees Celsius, but if there is a dense atmosphere, then the average temperature is about 19-23 degrees.
LHS 1140 b orbits on the edge of its parent star’s habitable zone, which means that liquid water may be present on the surface.
It was previously noted that the star is inactive, which means that the atmosphere of the planet was not blown away. If life originated on the object, then the radiation does not threaten it.
“The most breathtaking exoplanet I have ever seen.
Exoplanet LHS 1140 b is ideal for the search for extraterrestrial life,” said astronomer Jason Dittmann.
Our galaxy, the Milky Way, is filled with a huge number of interesting planets, a large part of which are considered as potentially habitable worlds.
Probably, life is an integral “ingredient” of the Universe, the origin and development of which is an absolute norm, and not an exception to the rules.
