# Gas escaping from the nucleus, as on any active comet

The extra acceleration is the rocket effect of gas escaping from the sunlit nucleus, as on any active comet.

**Still possible** Answers **1** question0

## Where it stands

**Still possible** Three pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- The acceleration rises and falls with gas production
- It is negligible far from the Sun on both legs

## What would rule it out

- An acceleration that persists at the same level after activity has stopped
- An acceleration too large for any measured gas production

## Evidence 3 for · none against
