Astronomers Have Discovered Rocky Exoplanet Named LTT 1445Ab

Astronomers have just discovered rocky exoplanet which is called LTT 1445Ab. It orbits the primary star of three red dwarfs that constitute the system LTT 1445, located around 22.5 light-years away.

“If you’re standing on the surface of that planet, there are three suns in the sky, but two of them are pretty far away and small-looking,” astronomer Jennifer Winters of the Harvard-Smithsonian Center for Astrophysics told New Scientist. “They’re like two red, ominous eyes in the sky.”

The team of researchers published the study to “The Astronomical Journal”.

Researchers have discovered rocky exoplanet by TESS. The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA’s Explorers program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. It was launched on April 18, 2018 atop a Falcon 9 rocket.

According to “LTT 1445Ab is very different from the 2016 discovery of HD 131399Ab, another exoplanet with three suns. The latter is a giant with a 550-year orbit around one of the stars in a triple system 340 light-years away”.

The new planet only clocks in at about 1.35 times the physical size of Earth. Into that size, it packs up to 8.4 times Earth’s mass, so it’s a lot denser than our home planet.

The website mentions that its surface temperatures would be a scorching 428 Kelvin (155 °C; 311 °F).

Sciencealert indicates [LTT 1445Ab could be a perfect candidate. Because it transits so often, there will be plenty of opportunities for observations. It’s only 22.5 light-years away – relatively close, in cosmic scales. Its red dwarf star is bright enough to back-light the atmosphere, but not so bright that the planet is completely outshone].
