Its surface is at 150 degrees Celsius and still has a large orbit.
NASA orbits the sonication satellite of transit exoplanet or more simply known as TESS, by its initials in English. This machine evidenced the existence of a new and interesting exoplanet.
The discovery was presented at the annual meeting of the American Astronomical Society in Seattle and, of course, being an exoplanet, we speak of a body outside our solar system. What is romance?
The body called HD 21749b seems to have the longest orbital period of the three planets identified so far by the TESS. It travels around its star in a relatively slow period of 36 days, compared to the other two planets called Pi Mensae b (a "super-Earth" with an orbit of 6.3 days) and LHS 3844b (a rocky world) with an orbit of only 11 hours).
The mother star of this exoplanet is about 53 light-years away, in the reticle of the constellation. Similarly, the body surface is at a constant temperature of 150 degrees Celsius app.
The subject, explained Diana Dragomir of the MIT Kavli Institute for Astrophysics and Space Research at the portal of the entity, is that generally planets that orbit away from their parent stars must be cool, but in this case, they observed that the temperature "We were lucky here and we got it. Now we can study it in more detail," he said.
The planet is about three times the size of the Earth, which places it in the category of "sub-Neptune" (a planet with up to 10 Earth masses). Likewise, scientists have said that it is unlikely that the planet is rocky and therefore habitable; It is more likely to be made of gas.
