Where it stands

Still possibleIts tests haven't settled it: one piece of evidence for, none against. It needs two reviews to be accepted.

What it predicts

Predicted anomalies of 2.9, −0.9, 20.1, 0.9, 3.2 and −1.3 mm/s for the six early flybys.

What would rule it out

Disagreement with well-measured flybys beyond errors.

Evidence 1 for · none against

Three of six early flybys reproduced within error; the others off by 1 to 3 mm/s.
