Using several telescopes, in particular the mostlarge European Southern Observatory (ESO VLT), astronomers have discovered a system consisting of six exoplanets, five of which revolve around the central one. The researchers believe that this system will explain how planets form and develop, including in the solar system.
While observing the star TOI-178, located about 200 light-years away in the constellation Sculptor, astronomers noticed two strange objects in the star's orbit.
It turned out that these were planets.Continuing observations, scientists found that the planets rotate around the star with almost the same rhythm and at almost the same distance. Astrophysicist Adrian Leleu from the University of Geneva says that it later turned out that not two planets revolve around the star, but five at once.
A new study finds that planetarythe system can include six exoplanets at once. Each of the five exoplanets, except the one closest to the center, moves in its own orbit, in other words, they are in resonance. This means that there are patterns that repeat as the planets rotate.
A similar resonance is observed in the orbits of threesatellites of Jupiter: Io, Europa and Ganymede. Io, the closest of the three to Jupiter, makes four complete revolutions around Jupiter for each orbit that Ganymede, the farthest one, and two complete revolutions for each orbit that Europa makes.
