Born in a young stellar association such as the Carina or Columba moving groups, tens of millions of years ago.

**Still possible** Answers **1** questionPublished0

## Where it stands

**Still possible** Its tests haven't settled it: two pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- The pre-encounter orbit matches a young moving group's motion.

## What would rule it out

- A Gaia-based traceback showing no young group consistent with the path.

## Evidence 2 for · none against

[Carina and Columba are the most plausible source regions, though only statistically.](https://mysteriesdept.com/mysteries/oumuamua/evidence/EVD0CSKCHQ861CF/carina-and-columba-are-the-most-plausible-source-regions)

Suggestive

FOR

[The orbit is consistent with Carina-group membership and a dynamical age of about 35 million years.](https://mysteriesdept.com/mysteries/oumuamua/evidence/EVD0CSKCHFE30HX/the-orbit-is-consistent-with-carina-group-membership-and-a)
