Large exoplanet lies just 42 light-years away
Astronomers on the prowl for potentially habitable planets have found a new candidate: a world seven times as massive as Earth in a nearby solar system.
The planet orbits a star about 42 light-years away in the constellation Pictor. The star, HD 40307, was thought to harbor only three planets, but sensitive data-filtering methods revealed the presence of three more. The farthest-out of these lies in a “sweet spot,” at a distance from its star where liquid water — and thus life — could exist.
