Astronomers Are Tracking Four Potential Interstellar Objects Now In Our Outer Solar System

Using detailed computer models of asteroidal-type objects between the Sun and Jupiter, two Harvard University researchers find that at least four known objects are likely to have origins from outside our solar system. After becoming gravitationally-trapped, the four potentially interstellar objects --- 2011 SP25, 2017 RR2, 2017 SV13, and 2018 TL6 --- are thought to spend most of their time between the orbits of Jupiter and Neptune. However, during their closest approaches to the Sun, they do pass through Earth’s neighborhood.
