Africa-Press – Rwanda. <\/strong><\/span>According to the Interactive Extra-Solar Planets Catalogue, humans have spotted some 4,878 planets in 3,604 solar systems other than our own. Termed exoplanets, only few have been found in the habitable zone around their parent star, and none have been confirmed to have life.<\/p>\n

There are few things that are standard or typical across the universe, but the exoplanet GJ 367b still manages to stick out as an oddball in Earthling discoveries. Astronomers at the German Aerospace Center\u2019s Institute of Planetary Research, using data gathered by NASA’s Transiting Exoplanet Survey Satellite (TESS), reported the find in a paper published in Science on Thursday.<\/p>\n

For starters, GJ 367b is one of the smallest exoplanets ever spotted, just slightly larger than Mars and just 70% the size of Earth. It\u2019s also only about 55% the mass of Earth, making it one of the lightest spotted, too. However, its density is impressively high: according to the scientists, the exoplanet clocks in at an average of 8.106 grams per cubic centimeter. That\u2019s not just denser than the Earth, which has an average density of just 5.51 grams per cubic centimeter, but it\u2019s also denser than solid iron, which has a density of 7.874 grams per cubic centimeter at room temperature.<\/p>\n

GJ 367b\u2019s star is relatively close, too, sitting just 31 light-years away. “From the precise determination of its radius and mass, GJ 367b is classified as a rocky planet,\u201d Dr. Kristine Lam, the study\u2019s lead author, said in a statement.<\/p>\n

“It seems to have similarities to Mercury. This places it among the sub-Earth sized terrestrial planets and brings research one step forward in the search for a ‘second Earth,\u2019\u201d she added.<\/p>\n

However, it isn\u2019t the first such planet to be spotted, either: an exoplanet designated Kepler 107c, orbiting a star 1,700 light-years away, was found in 2019 to have an even higher density of 12.65 grams per cubic centimeter and is about 1.5 times as wide as the Earth. In its case, however, scientists believe it to be the remnant core of an even larger planet that survived some kind of cataclysmic collision.<\/p>\n

TESS uses the same method as Kepler in that it looks for stars that \u201cwobble\u201d or regularly dim and brighten – possible signs they have exoplanets orbiting them, which by calculating the star\u2019s properties, can then have their own properties largely derived. However, TESS can process 400 times the amount of sky as Kepler, making it a far more effective tool in the search for planets outside our solar system.<\/p>\n
