Kepler-385 System: A Rare Seven-Planet System Discovered by NASA’s Kepler Telescope

2023-11-06 12:06:03
Continuing to analyze data from the retired Kepler Space Telescope, scientists’ latest research confirms that the Kepler-385 system consists of seven sultry planets, each of which is larger than the Earth and smaller than Neptune. After more than nine years of searching, NASA’s Kepler Space Telescope ended its mission in 2018. During this period, it discovered thousands of planets and produced a large amount of data for exoplanet scientists to analyze. Among them, the Kepler-385 system is regarding 4,670 light-years away from us. , some planets in the system were confirmed in 2014, but some objects have yet to be confirmed as planets.

Other famous examples are the TRAPPIST-1 system composed of 7 Earth-like planets. Kepler-385 is a sun-like star with a volume regarding 1.1 times that of the sun and a temperature 5% higher than the sun. The two closest planets in the system, Kepler-385 b and Keplar-385 c, are slightly larger than the Earth and may be composed of rocks. And has a thin atmosphere. Kepler-385 b has a mass of regarding 12.8 times that of the Earth, a width of 2.7 times that of the Earth, and an orbital period of 10 days. Keplar-385 c has a mass of regarding 13.2 times of the Earth. Its orbit is perfectly circular, and it takes regarding 15 days to orbit its parent star.

The other five planets have radii regarding twice that of the Earth and may be shrouded in thick atmospheres. Most of the exoplanets discovered by the Kepler telescope are extremely close to their parent stars and are basically too hot to be habitable. But if it is a warm super-Earth, there may be a chance to provide clues regarding habitable climate. These observations also show that the solar system is not a typical galaxy. Somehow, the solar system avoided forming a system like Kepler-385, so we can exist. More data are needed to consider whether the solar system is a rare entity.
