## Where it stands

**Disputed** One piece of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- A high albedo; ejection 0.4-0.5 billion years ago from a young system.

## What would rule it out

- An agreed mass budget showing too few fragments, or an analogue with a dark surface and nitrogen absent.
