Venus May Have Had a Moon for Nearly 2 Billion Years—Before It Ate It

Recent scientific analysis suggests that the planet Venus may have once been orbited by a moon. The current theory posits that this moon did not drift away or collide with another celestial body, but was instead destroyed by Venus itself. This process describes a scenario where the planet effectively consumed its own natural satellite over an immense geological timescale.

The outlet emphasizes the potential existence of this long-lost moon and the specific mechanism of its disappearance. While the report highlights the scientific belief that the planet destroyed its moon, the coverage does not provide a list of the specific scientists involved or the specific astronomical data used to reach this conclusion. The focus remains on the theoretical timeline of the moon's existence and its eventual fate.

To understand why this matters, one must consider the current state of Venus, which is known to have no moons. Most planetary models for our solar system account for the current arrangement of satellites; however, the idea that a planet could 'eat' its own moon introduces a different dynamic regarding planetary gravity and orbital decay that scientists are now exploring. Future observations will likely focus on whether there is physical evidence of this destroyed moon remaining within the composition of Venus.
