Table 3, right column of page 3. Retrieved April 25, Prior to the discovery of Proxima Centauri bthe TV documentary Alien Worlds hypothesized that a life-sustaining planet could exist in orbit around Proxima Centauri or other red dwarfs.

Stocks around the world limped into the end of a dismal year that’s seen bear markets in equities from Proximoo to Germany. Estimates from various agencies range from 40 per cent to 50 per cent increase in global consumption over the next 25 years.


Any exoplanet in this star’s habitable zone would likely be tidally lockedresulting in a relatively weak planetary magnetic momentleading to strong atmospheric erosion by coronal mass ejections from Proxima Centauri. They also tentatively detected two additional features: A slow-moving probe would have only several tens of thousands of years to catch Proxima Centauri near its closest approach, and could end up watching it recede into the distance.

If the planetary orbits are close to face-on as observed from Earth, or in an eccentric orbit, more massive planets could have evaded detection by the radial velocity method.

The first indications of the exoplanet were found in by Mikko Tuomi of the University of Hertfordshire from archival observation data.

Though Proxima Centauri is the nearest bona fide star, it is still possible that one or more as-yet undetected sub-stellar brown dwarfs may lie closer. Bulletin of the American Astronomical Society. Retrieved July 12, Get to Know Us.

The equilibrium temperature of Proxima b is estimated to be proxio the range of where water could exist as liquid on its surface, thus placing it within the habitable zone of Proxima Centauri, [24] [27] [28] although because Proxima Centauri is a red dwarf and a flare star, whether it could support life is disputed.

Relative to the Sun, therefore, the density is: The Alpha Centauri system.
