Detecting a strange planet orbiting 3 stars

A group of astronomers said on July 7 that a strange planet outside the solar system has been discovered, orbiting 3 stars.

The study, published in the July 7 issue of the American Journal of Science, is considered to be a remarkable discovery in the universe of planets only orbiting a host star [also known as the sun of the planet. -ND].

Recently, astronomers have also discovered some planets with up to two suns (binary star system, binary star system). However, a planet at the same time turning around to 3 stars is extremely rare.

The strange planet was named HD 1311399Ab , located about 340 light-years from Earth in the constellation Sagittarius (Centarurus). This gas body is said to be relatively young - about 16 million years old.

This is the smallest planet discovered outside the Solar System. Its mass is four times that of Jupiter (the largest asteroid in the Solar System).

Through observation of the SPHERE telescope , this strange planet orbits the brightest point of three stars in a very long and wide line. All 3 stars turn around each other.

The astronomers discovered this strange planet using the astronomical tool SPHERE located at the Southern European Observatory (ESO) in Chile. This is one of the most modern astronomical tools specialized in searching planets orbiting other stars.

The huge city of this tool is very sensitive to infrared light, capable of detecting the heat sign of planets in and out of space. At the University of Arizona research group, we want to know what will happen if one day in that strange planet comes three moments of Dawn and Sunset.
