A shard torn from a larger body by tides during a close pass by its star, then ejected.

**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

- Elongated shapes, baked surfaces and buried ice are common among interstellar asteroids.
- Single giant-planet systems around low-mass stars eject such fragments.

## What would rule it out

- Population models showing too few elongated fragments to make one detection likely.

## Evidence 2 for · none against

[About 3 per cent of objects ejected from a single giant-planet system would be extremely elongated.](https://mysteriesdept.com/mysteries/oumuamua/evidence/EVD0CSKCJEP1SWJ/about-3-per-cent-of-objects-ejected-from-a-single-giant)
