They discover a planet that revolves around three stars | Digital Trends Spanish

So far, it is known that there are many planets that revolve around two stars and the most popular example may be that of the fictional Tatooine from Star Wars. But for a planet to do it around three stars is something completely different, and that’s exactly what what they have found a group of astronomers from the University of Nevada.

This planet is located more than 1,300 light years from Earth and the evidence found by the ALMA telescope suggests the existence of an object whose orbit is called circumtriple and that could be the first planet in a solar system in formation.

The system in question is called GW Orionis and has three stars, around which traces of a ring of dust were discovered. The researchers, reconstructing the composition of GW Orionis with the data obtained from ALMA, conclude that the most feasible explanation for these traces is the presence of one or more planets of the gaseous type.

These planets are the size of Jupiter and according to the theory of the origin of planets and solar systems, they are the first to form. Jeremy Smallwood, one of the researchers behind the finding, indicated that the results are interesting because they give ground to this theory and because they suggest that “the formation of new planets is much more active than we thought.”

However, for now this body is not visible; For this, new data and observations will be necessary to be carried out with the ALMA telescope and which could provide new evidence in the future, confirming that it is the first (known) planet to rotate around three stars.
