Proxima Centauri b is the closest exoplanet to Earth, [19] at a distance of about 4.2 ly (1.3 parsecs). [4] It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, [1] over 20 times closer to Proxima Centauri than Earth is to the Sun. [20] As of 2021, it is unclear whether it has an eccentricity [e] [23] but Proxima Centauri b is unlikely to have any obliquity. [24]
Mikko Tuomi is a Finnish astronomer from the University of Hertfordshire, most known for his contributions to the discovery of a number of exoplanets, among them the Proxima Centauri b which orbits the closest star to the Sun. Mikko Tuomi was the first to find indications of the existence of Proxima Centauri b in archival observation data. [2]
Before the discovery of Proxima Centauri b, the TV documentary Alien Worlds hypothesized that a life-sustaining planet could exist in orbit around Proxima Centauri or other red dwarfs. Such a planet would lie within the habitable zone of Proxima Centauri, about 0.023–0.054 AU (3.4–8.1 million km) from the star, and would have an orbital ...

The planet, dubbed Proxima b because it orbits Proxima Centauri, is thought to be a rocky and slightly more massive than Earth -- but that's not all. Scientists discover Earth-like planet orbiting ...
Film and media company Buffalo 8 has acquired worldwide rights to “Invaders from Proxima B,” the science fiction comedy from writer-director-star Ward Roberts (“Westworld,” “Agents of ...
The European Southern Observatory (ESO) announced the detection of a planet orbiting the third star in the Alpha Centauri system, Proxima Centauri in August 2016. [15] [16] The planet, called Proxima Centauri b, orbits within the habitable zone of its star. It could be a target for one of the Breakthrough Initiatives' projects.
English: This plot shows how the motion of Proxima Centauri towards and away from Earth is changing with time over the first half of 2016. Sometimes Proxima Centauri is approaching Earth at about 5 kilometres per hour — normal human walking pace — and at times receding at the same speed.
