UC Riverside study: Venus likely consumed its own moon

Mechanism explainedRotation speed determines moon survival

3 Sep 16 · 7d ago · 1 article · 1 source · development 3 of 3

The study identifies planetary rotation as the key factor. Earth rotates in 24 hours, transferring energy that pushes its moon outward at 4 cm per year. Venus rotates once every 243 Earth days, so a moon would receive no outward push and instead spiral inward due to tidal forces until crossing the Roche limit at roughly 17,000 km from Venus's center.

“We know that the moon is slowly moving away from the planet, at a rate of around four centimeters per year. That movement is closely tied to Earth's relatively rapid rotation.”
