Why does Venus have no moon? New theory points to celestial cannibalism

The record

Written from the 1 report below. Nothing here is unsourced.

A team of astrophysicists at the University of California, Riverside proposed a new theory for why Venus has no moon, publishing the research in The Astrophysical Journal.
Venus rotates extremely slowly, taking 243 Earth days to complete one spin, and the researchers say this doomed any former satellite to spiral inward and crash into the planet.
Computer models simulating hypothetical Venusian moons of various sizes showed all of them eventually collapsing into the planet.
Such a moon-gobbling event likely happened within the first billion years of Venus's roughly 4.5-billion-year history.
The finding matters because Venus, often called Earth's twin, is studied closely for clues about Earth's history and future.

NASA's DAVINCI+ and VERITAS missions, set for launch in the late 2020s or early 2030s, to study Venus's atmosphere and geologic features.
Whether future evidence can confirm that Venus ever had a moon, since no proof currently exists.
