Scientists have probably discovered the first planet to orbit three stars

The exciting discovery of potential planets orbiting three stars instead of one or two stars could change human perception of the planet formation process. Unlike our solar system, which has only one star, researchers believe that half of a star system consists of two or more stars that are interconnected by gravity.

They have gone a step further, and in a distant star system just 1,300 light-years from Earth, researchers at the University of Nevada, Las Vegas (UNLV) have probably identified the first known planet to orbit three stars. The GW Orionis star system, which probably has a planet or planets orbiting all three of its stars.

Despite the discovery of many extrasolar planets, so far no planets orbiting all three stars Orbit has not been discovered, and perhaps the planet GW Ori is the first. Using observations from the Atacama Large Millimeter Array (ALMA), UNLV astronomers analyzed three dust rings around three stars called protoplanetary disks, which are essential for planet formation.

Scientists recently discovered a gap in this pre-planetary disk. The research team examined various reasons for the formation of this gap, including that it was created by the gravitational moment of three planets. But after a comprehensive modeling of GW Orionis, they found that the most likely and perhaps most attractive explanation for the disk space was the existence of one or more massive Jupiter-like planets, according to Jeremy Smallwood. Jeremy Smallwood (lead author of a recent article) Gas giants are usually the first planets to form in stellar systems, followed by terrestrial planets such as Earth and Mars.

This potential planet is not visible on its own, but A new finding published in the September issue of the Monthly Notices of the Royal Astronomical Society shows that the gas planet GW Orionis is the first three-star planet ever discovered. Researchers hope that more observations by Alma in the coming months will provide direct evidence of this cosmic phenomenon. "The planet is moving far more than we thought."
