Researchers have discovered five exoplanets and eight planets around our nearby stars. According to the scientists, these planets contain a “cold Neptune” and two super-Earths that are potentially habitable.
The two super-Earths, GJ180d and GJ229Ac are orbiting two small dwarf stars that are 19 and 40 light years away from sun. On the other hand, the ‘cold Neptune’ is located around a similar star that is 29.5 light years away.
In a recently published paper detailing the study, the researchers said that the super-Earths are 7.5 and 7.9 times the mass of Earth and take 106 and 122 Earth days to complete one orbit around their stars respectively. As for the cold Neptune, the planet has similar mass to the gaseous planet in our solar system.
Fabo Feng, lead study author and astronomer at the Carnegie Institution for Science said, “GJ180d is the nearest temperate super-Earth to us that is not tidally locked to its star, which probably boosts its likelihood of being able to host and sustain life.”
Jeffrey Crane, study co-author and astronomer at the Carnegie Institution for Science added, “We eventually want to build a map of all of the planets orbiting the nearest stars to our own solar system, especially those that are potentially habitable.”
