   Study suggests Venus swallowed an ancient rocky moon

   Venus may have consumed a rocky satellite billions of years ago, according to a recent astrophysics study. Researchers propose that the planet's slow rotation contributed to the moon's demise, leading Venus to gobble up the celestial body. This theory provides a possible explanation for why Venus currently lacks a moon, unlike its planetary twin, Earth. The research focuses on the orbital dynamics and rotational speeds that would have made such a satellite unstable over time.

   Why it matters

   Venus and Earth are often compared due to similar size and composition. Understanding the early satellite history of Venus helps scientists model how planetary systems evolve and why some planets retain moons while others do not.

   What is confirmed

   • An astrophysics study suggests Venus may have swallowed its moon.
   • The event likely occurred billions of years ago.

   Still unconfirmed

   • The slow rotation of Venus caused the planet to swallow its moon.

   What to watch next

   • Peer review or corroboration of the orbital dynamics model by other astrophysics teams.
   • New data from Venusian surface missions that might show evidence of an ancient impact.
