- Proxima Centauri's Awesome Earth-Like Planet
Proxima Centauri b is a super Earth exoplanet that orbits an M-type star. Its mass is 1.07 Earths, it takes 11.2 days to complete one orbit of its star, and is 0.04856 AU from its star. Its discovery was announced in 2016.
Proxima Centauri is a member of the Alpha Centauri star system, being identified as component Alpha Centauri C, and is 2.18° to the southwest of the Alpha Centauri AB pair. It is currently 12,950 AU (0.2 ly ) from AB, which it orbits with a period of about 550,000 years.
7 Φεβ 2021 · The tidal-locking of the planet produces the symmetrical pattern of Proxima Centauri b surface temperature: higher temperatures in the region of the sub-stellar point, with the presence of an open ocean (Tice = 273.15K) and colder temperatures in the night-side of the planet.
28 Ιαν 2020 · They found that Proxima b’s hypothetical cloud layer would act as a shield, deflecting the Sun’s radiation from the surface and lowering the temperature on Proxima b’s sun-facing side.
30 Νοε 2022 · We have modeled Proxima b’s space weather using this map and compared it with the results from the proxy magnetogram. We also computed models for a high-resolution synthetic magnetogram for Proxima b generated by a state-of-the-art dynamo model.
Proxima Centauri is a red dwarf star, with only a fraction of the mass of the sun. Because of their small sizes, the nuclear fusion cores of red dwarf stars are much closer to their surfaces....
