Exoplanet-hunters have found a rare star system containing seven planets after poring through data from a space telescope that stopped working in 2018. Exoplanets are planets that orbit around stars other than our sun.Kepler 385, a roughly sun-sized star around 4,670 light-years distant in the constellation Cygnus, the swan, was first suspected of having planets in 2014. They appeared in data from NASA’s Kepler Space Telescope.
However, new analysis has confirmed the presence of seven planets, all larger than Earth yet smaller than Neptune. The two planets closest to their host star are thought to be rocky and may have thin atmospheres.Jack Lissauer, a research scientist at NASA’s Ames Research Center in California’s Silicon Valley and lead author of a paper.
The Kepler Space Telescope observed nearly 200,000 stars to calculate what fraction of stars in the Milky Way have Earth-size planets in their habitable zone. The mission found 2,662 exoplanets between 2009 and 2018 before technical problems ended it. However, scientists will be using its data for many years.
