Researchers propose that Venus may once have had a moon that gradually spiraled inward and crashed into the planet. Simulations show that Venus’s extremely slow rotation would prevent a satellite from migrating outward like Earth’s Moon, instead causing it to lose orbital energy and fall toward the surface. The hypothesis could help explain Venus’s unusual rotation and may have implications for the evolution and habitability of slowly rotating exoplanets. https://iopscience.iop.org/article/10.3847/1538-4357/ae9d6c
