Both comets and stars are great dancing partners. Their gravitational relationship is one that astronomers have never seen, but they suspected it for a very long time. Well, now they’ve seen it. For the very first time, a Polish group has found two nearby starts, and it looks like they pulled their partners, swaying them into orbits around our Sun.
Astronomers found this stellar duo after they studied the movements of more than 600 stars, which appeared 13 light-years away from the Sun. These new findings prove a theory that was born more than half a century ago. These dances are really rare, and we know that now.
The Oort Cloud is found on the edge of our solar system. The icy group was left behind after the formation of the solar system, which created a giant shell, encircling our home system, which extends from about 66 times the distance to Neptune to 9.23 trillion miles – that’s about 14.9 trillion kilometers – away from the Sun.
Comets and Stars Are Partners in Dancing
Scientists believe that Oort Cloud is actually a reservoir for comets, for those that take more than 200 years to orbit the Sun. One of the best examples is Comet Hale-Bopp, which has a 2.500-year orbit.
Since the existence of the cloud was firstly proposed by Jan Oort back in the 1950s, scientists thought that, at some point, a passing star can pick up an object, and simply send it on a ride through the solar system. This ride is the one that brings some of the comets to our skies.
Scientists spent years to try to find proof of these stellar dances, but they didn’t find anything for sure up until now.
