Exoplanet discovered around neighbouring star

It orbits Barnard's star, which sits "just" six light-years away.
this newly discovered world has a mass 3.2 times bigger than the Earth's.
 
The BBC article also says that it looks like a superearth, around 3.2 times the mass of Earth, and may be relatively similar to Titan:

The planet, Barnard's Star b, is about as far away from its star as Mercury is from the Sun. It's the second closest exoplanet to Earth after Proxima Centauri b, whose discovery was announced in 2016.

Barnard's Star is an extremely dim object known as a "red dwarf"; it's about 3% as bright as the Sun, so it emits far less solar energy.

The planet orbits beyond a boundary called the "snow line", which is past the traditional habitable zone, where water can remain liquid on the surface.

On distance alone, it's estimated that temperatures would be about -150C on the planet's surface. However, a massive atmosphere could potentially warm the planet, making conditions more hospitable to life.
