AI Summary

Scientists note that Venus, despite sharing size, mass and internal structure with Earth, lacks a natural satellite. New research from the University of California, Riverside proposes that the planet likely captured and then absorbed a moon, explaining its current moon‑less state. Earlier hypotheses suggested the moon may have been destroyed by a massive impact, while alternative ideas argued Venus never experienced a moon‑forming collision. The study adds a concrete mechanism to the longstanding question of why Earth’s twin is moon‑free.
