Astronomers have discovered a new super-earths with very short year

Astronomers from the University of British Columbia played a key role in the discovery of new planets outside the Solar system. Researcher Jamie Matthews confirmed the existence of super-earths at a distance of 180 light-years from our planet. The opening was given the name HIP 116454 b.

The newfound planet is classified as a "super-Earth". It is 2.5 times bigger than our planet in diameter and 12 times by weight.

This can be a miniature version of the ice giant planet Neptune. But more interesting is that three quarters of the surface may be under the cover of water, — says the researcher.

Writes Phys.org the signal indicating the existence of new exoplanets, first discovered by American researchers who studied the data obtained by Kepler space telescope NASA. However, they do not have time to recheck the information, since the satellite is moved to observe different parts of the sky.

They were rescued by the Canadians, who made the telescope MOST (Microvariability and Oscillations of STars satellite) to the desired part of the sky, and then confirmed the find of Kepler. The spacecraft has recorded the change in the brightness of stars when passing by it on the planet.

In the calendar of this planet a few pages. The period of its revolution around the parent star is 9.1 days. That's how much last year on the planet, HIP 116454 b, says Matthews.

The new planet is too close to the sun to be habitable. However, Matthews hopes that he has discovered an exoplanet in the system of this star. According to the scientist, the other planets may have more suitable conditions for habitability.

This super-earths can be neighbors, and they may be in the habitable zone of a star. Only time and careful studies of this system show.

The results of the study are being prepared for publication in the journal of TheAstrophysical Journal.
