Another super-Earth discovered, potentially habitable

Researchers discovered what appears to be another “super-Earth” planet–a potentially Earth-like planet that is much larger than Earth, but smaller than a gas giant like Jupiter. Although other “super-Earth” planets have been discovered recently, they are pretty rare, so the discovery of another “super-Earth” planet is pretty exciting.

This new planet, HD 40307g, is the sixth planet in a six-planet system approximately forty-four light years from Earth. As Space.com explains, this planet orbits at a distance of 55.8 million miles from its star, HD 40307. And this distance “puts it into HD 40307’s habitable zone, the region in a planetary system where liquid water can exist on a planet’s surface,” meaning this planet could potentially support life as we know it.

An international team of astronomers made the discovery using the High Accuracy Radial Velocity Planet Searcher (HARPS) at the European Southern Observatory. But as astronomer Phil Plait of Discover Magazine points out, HD 40307g is still considered a planet candidate; it has not yet been confirmed.
