They discover the most massive ‘super-Earth’ ever observed: it’s 200 light-years away



This discovery represents a new breakthrough in exoplanet exploration, since only small rocky planets were known.

A new astronomical discovery has been recorded in planetary science after NASA’s Transiting Exoplanet Survey Satellite (TESS) telescope. Capturing the most massive ‘super-Earth’ ever, 200 light-years away .

A giant planet far away, It was christened TOI-1075b and its radius is 1.8 times that of Earth In fact, it is one of the largest land-based exoplanets ever discovered. And even belongs to a special group whose research is just beginning.

this celestial body It has been observed since 2013, when the Kepler telescope first captured it. I could not immediately identify what it was.

Astronomers have described it as “a bizarre dichotomy of exoplanets found in telescopes,” Portal says. gizmodo.

Late 2017, Investigation I was able to explain the phenomenon better by explaining it in more detail. Although at that time there were no clear characteristics.

It turns out that until then, only small rocky (Earth-like) and gaseous giant (Jupiter-like) exoplanets were known. But this one was different, rocky and huge.

The most massive super-Earth has opened a new gap in the search for exoplanets

It was there that astronomers began to explore the idea of ​​an intermediate characterization. Possible rocky planets with radii 1.5 to 2 times that of Earth .

The phenomenon was considered a “gap” because these types of planets are rare.

It’s finally the end of October this year research published We were able to classify TOI-1075b. And it now has the approval of scientists in the area.

There, in addition to observations from the TESS telescope, observations from the Planet Finder Spectrograph (PFS) from the Magellan II telescope will be presented. His more detailed measurements show a mass 9.95 times that of Earth. .

Similarly It was also concluded to be uninhabitable because it is so close to the star and undergoes temperatures considered “hell”. .

Because of its orbital period, even its days are short. The latter barely reaches 14 and a half hours.
