# Four to eight times 10^28 molecules a second

3I/ATLAS's water production peaked at about 4 to 8 × 10^28 molecules a second after perihelion.

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

## Where it stands

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

## What would rule it out

- Independent measurements near 6 November 2025 above 2 × 10^29
