That now infamous interstellar object that came zooming through our solar system in 2017 in fact is an interstellar object that did not originate from the solar system we live in. According to a new study, the object appears to actually be a chunk of a foreign planet that has yet to be identified. In fact, scientists say that the 148 unknown object not only is a chunk of a likely destructed planet somewhere out there — it is made of nitrogen.
The authors say that the destruction happened likely 500m years ago although nobody’s quite sure. Given that the piece appears to be from a planet that did not originate in our solar system it is unclear just how or when it actually happened.
