## Where it stands

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

## What it predicts

- A model that fits all nine flybys, including the nulls, and predicts future ones.

## What would rule it out

- A conventional or modelling explanation confirmed by re-analysis.

## Evidence 1 for · 2 against

[Six flybys fit a formula with a constant equal to twice Earth's equatorial speed over c.](https://mysteriesdept.com/mysteries/flyby-anomaly/evidence/EVD0CWYECDY5B4V/six-flybys-fit-a-formula-with-a-constant-equal-to-twice)
