According to Space.com, an American space science media outlet, on the 4th (local time), the National Aeronautics and Space Administration (NASA) made observations using the Kepler Space Telescope. During detailed analysis of the data, seven planets orbiting around a star were identified in space 4672 light years away from Earth. This group of planets, named the ‘Kepler-385 Planetary System’, is a unique case in space science. Most planets are caught in the gravitational pull of a central star and move in orbit, but among the stars discovered so far, it is rare for a star to have more than six planets. In the universe, 39 light years away from Earth, seven planets orbit around one star. This is why the ‘Fist-1 planetary system’ is considered a kind of ‘separate species’. Our solar system, which has eight planets, is a very unique case. The central star of the Kepler-385 planetary system discovered by NASA researchers is 1.1 times larger and 5% hotter than our sun. Researchers analyzed that the two planets orbiting close to this central star are likely to be made of rock like Earth and Mars. It was assumed that the five outer planets were likely to be gaseous planets. An imaginary diagram of the seven planets in the ‘Kepler-385 planetary system’ orbiting around each other.

Gaseous planets do not meet this premise. In that respect, the two planets orbiting the inner orbit meet one of the many conditions for the birth of life. The problem is temperature. The first planet closest to the central star is only 10% of the distance between Earth and the Sun, and the second closest planet is only 13%. The first and second planets are so hot that their surfaces are directly hit by radiation pouring from the central star. It seems to be correct. Strong radiation is an unfavorable condition for the birth of life. Looking at the observation results confirmed to date, it is unlikely that life forms known to mankind exist in the Kepler-385 planetary system. However, NASA researchers discovered an unusual phenomenon through this discovery. When there are many planets orbiting a central star, the orbits of each planet are close to being perfectly circular. This phenomenon was confirmed compared to when there were one or two planets orbiting a central star. NASA researchers discovered these facts by closely analyzing observation data from the Kepler Space Telescope, which was launched in 2009 and performed a mission until 2018. Fuel The operation of the Kepler Space Telescope stopped due to exhaustion, but because of the enormous amount of data already collected, previously unknown information was discovered in the process of examining it in detail. NASA researchers said, “This study is aimed at exploring areas beyond the solar system, such as the Kepler-385 planetary system. “It will allow us to look into the distant universe with more insight,” he expressed his expectation.
