UK Met Office forecasts weather on Proxima B — 4 light years away

  |   Tech News

Scientists at Exeter university applied the UK Meteorological Office’s computer model of weather and climate to Proxima B, an Earthlike body discovered last year in orbit around Proxima Centauri, a star that lies just 4 light years away.

Although hard information about Proxima B will remain sparse until astronomers have made further observations, Exeter’s exoplanet experts say they already know enough to use the Met Office model to make preliminary simulations of its climate — a step toward the long-term goal of finding out whether conditions there could support life.

First results, published in the journal Astronomy & Astrophysics, suggest that Proxima B could indeed be habitable. The Exeter astronomers made various assumptions about the planet’s atmospheric composition and its movement around its parent star. These suggest that it has a remarkably stable climate regime.
