Spanish scientists have discovered a super-earth-type exoplanet. It could have liquid water, a necessary condition for life to develop there, as we know it.
Researchers from the University of Oviedo (north) and the Instituto de Astrofísica de Canarias (Spanish archipelago in the Atlantic), made the finding using data from the Kepler space telescope, designed to discover exoplanets through the 'transit' method, which takes place when a planet passes in front of its star and absorbs part of the star's light.
The exoplanet, named K2-286b, is outside the Solar System, and orbits around a red dwarf star, the most abundant in the galaxy and somewhat smaller than the Sun.
The planet has an orbital period of 27.36 days and an equilibrium temperature that could be around 60ºC.
"We have verified that the activity of the star is moderate compared to other stars with similar characteristics, which would increase the chances that the planet was habitable", says Javier de Cos.
And the planet is at the inner limit of the habitable zone, so that, under the right conditions, it could maintain liquid water on its surface, an essential requirement for the development of life as we know it.
K2-286b is of special interest not only because it is located in the habitable zone of its star, but also because it is among the most suitable for atmospheric characterization with the future James Webb Space Telescope, as well as for ground monitoring to determine its mass accurately, explains a statement from the University of Oviedo.
