Astronomers have found two possible orphaned planets. world News



Astronomers have discovered in the Milky Way planets that may prove to be "orphans", ie, exist without a mother's star.

It is worth noting that it is currently impossible to say safely if these planets are "hikers". Researchers reported on their discovery on site arXiv, reporting "DS".

As scientists emphasize, planets that differ from the stars do not in fact send light. However, they can be detected using the gravity microlensing method. With that, researchers try to notice the planets that fly freely against the background of the stars. In this case, the planet plays the role of a lens, and the star increases its brightness for a while.

Researchers were able to detect two events named OGLE-2012-BLG-1323 and OGLE-2017-BLG-0560. The first of these can be caused by a planet that passes the earth or the size of Neptune and the other – the size of Jupiter or a brown dwarf. At the same time, the researchers do not reject the possibility that both planets are associated with the parent star but have very wide paths.
