Recently, a rocky extrasolar planet with a mass similar to Earth was identified near Proxima Centauri, the nearest star to our Sun. This newly discovered planet is named as Proxima B and is in an orbit that would allow the planet to have a liquid form on its surface. Thus, it has raised a question regarding the presence of habitat.
According to Space Daily, a study to be published in The Astrophysical Journal Letters, led by a team of international researchers at the Marseille Astrophysics Laboratory has determined the properties and dimensions of the planet's surface which actually favors its habitability feature. The team states that Proxima could be an ocean planet, similar to that of subsurface oceans detected inside icy moons around Jupiter and Saturn.
