A TESS mission discovered an incredible number of three new worlds which put us in total awe. NASA once again did the impossible with the help of its top satellite.
TESS, or its formerly known as the Transiting Exoplanet Survey Satellite, is a NASA Astrophysics Explorer mission developed and created by MIT in Massachusetts, and administered by NASA’s Goddard Space Flight Center. TESS strikes once again by unveiling one of its newest missions results, the discovery of three new worlds. One of them has the size a little bit bigger than our planet and the rest of them are not from our solar system, orbiting instead a close star. These planets represent a true challenge for the astronomers.
TESS Object of Interest is a weak, cold star more frequently recognized by its name, UCAC4 191 004642. This a M-type dwarf star is significantly little than the Sun, in size and mass, too, and its surface is cooler than the Sun’s. The planetary system is about 73 light-years away in the southern constellation of Pictor.
The deepest planet, TOI 270 b, is more like a rocky land, being larger than the Earth. It orbits the star each 3,4 days at a distance that is 12 times closer than Mercury orbits the Sun. The other two planets, c and d, are larger than Earth, about 2,4 and 2,1, and orbit the star every 5,7 and 11,4 days. What’s interesting is that the planets have similar dimensions with Neptune.
The team, however, try to benefit further of this research, because they hope it will reveal extra information about other planets beyond these recent planets. Further studies may scientists come in help with additional discoveries of rocky planets that maybe they will be at larger distances from our solar system.
