There’s a super-Earth among the 15 newly discovered planets and it could host water

indiatoday.in

Astronomers have discovered 15 new planets orbiting small, cool stars named red dwarfs near our solar system. Among these new planets is a potentially habitable ‘super-Earth’ that could have liquid oceans like ours.

The planet, known as K2-155d, has three transiting super-Earths. It is 1.6 times the size of Earth and is within the host star’s habitable zone 200 light years away.

KEY FACTS ON THE DISCOVERY:

1.The findings, published in The Astronomical Journal, are based on data from NASA Kepler spacecraft’s second mission, K2, and follow-up observations using ground-based telescopes, including the Subaru Telescope in Hawaii and the Nordic Optical Telescope (NOT) in Spain.

2.Based on climate simulations, researchers say the new Earth-like planet, K2-155d, could have liquid water on the surface.

3.A more precise estimate of the radius and temperature of the K2-155 star would be needed to conclude definitively whether K2-155d is habitable.

4.A key outcome of the current studies was that planets orbiting red dwarfs may have remarkably similar characteristics to planets orbiting solar-type stars.

5.Currently on the fastest spacecraft New Horizons, which travels at 51,500kmh, it would take more than four million years to get to K2-155d.

With the planned launch of NASA’s Transiting Exoplanet Survey Satellite (TESS) in April 2018, scientists are hopeful that even more planets will be discovered.
