Another possible interstellar visitor... May 21, 2018 7:03 pm RL

And it has likely been here a lot longer than we have…

If ‘The Expanse’ series has taught me anything it is that we should leave it the hell alone! :)

Unlike ‘Oumuamua, the interstellar object which briefly visited the Solar System earlier this year, 2015 BZ509 (affectionately known as BZ) seems to have been here for 4.5 billion years.

This makes it the first known interstellar asteroid to have taken up residence orbiting the Sun.

It is not yet known where the object came from.

“That’s what we need to figure out next,” laughs Dr Fathi Namouni from the Universite Cote d’Azur, one of the study’s authors.

“Because ‘Oumuamua was just passing by… it’s not that difficult to go back and pinpoint where it came from,” he told BBC News. “BZ reached the Solar System when it was forming, when the planets themselves were not exactly where they are now. So it’s a little more tricky to figure out where it came from.”

Its Retrograde orbit isn’t hard proof of extra-solar origin, but it just might be a refugee from one of our sibling suns that shared our crowded clouded nursery 4.5 billion years ago- or 18 Galactic Years ago…
