For the radial velocity of Proxima Centauri, Kervella and Thévenin used a new high-precision measurement determined by the team conducting the Red-Optical Planet Survey (ROPS) of 15 nearby red dwarfs (including Proxima) which employed the UVES spectrometer on the 8.2-meter Very Large Telescope (VLT, UT2) at the European Southern Observatory’s facility at Cerro Paranal in the Chilean Andes. A faint additional signal was detected in 2019 using radial velocity data with a period of 5.15 days. [41], In 2002, optical interferometry with the Very Large Telescope (VLTI) found that the angular diameter of Proxima Centauri is 1.02±0.08 mas. In it, they spotted a signal that could be another planet in orbit around Proxima Centauri. Proxima Centauri is a red dwarf star with a mass about an eighth of the Sun's mass (M☉), and average density about 33 times that of the Sun. [68] Several attempts to detect a transit of this planet across the face of Proxima Centauri have been made. Proxima Centauri has two known planets. Possible explanations for the signal include undiscovered exoplanets or statistical noise. When combined with Earth-based images, the result will be a record-setting parallax measurement. If Proxima Centauri were bound to its pair of Sun-like neighbors, it was likely near apastron (the farthest point in its eccentric orbit).

132, No. This could have an impact on the initial volatile inventory, evolution and, ultimately, the potential habitability of Proxima Centauri b. If I plot the projection of the orbit on the skyplane using the same code that gives correct results for the Alpha Centauri AB orbit from Kervella et al. They also suggest that the planet could be seen directly with future telescopes. Six single stars, two binary star systems, and a triple star share a common motion through space with Proxima Centauri and the Alpha Centauri system. If the planet is there, it’s at least six times as massive as Earth—making it what’s called a super-Earth—and it takes 1,936 days to loop once around its star.
