While it is "floating fact" Venus has no moons they are still looking into why. One theory which hasn't been fully debunked yet is the moon we have may have been a Venus moon at one point.
Crazy stuff.. but awesome to know they are diving into this to understand why Venus either had a moon or didn't. A partial fact that debunks the theory above is the relation between isotopes between our planet and our moon. However there have been multiple theories not fully debunked yet! So I wouldn't consider Venus never having a moon to be 100% fact until they deeply debunk the theories.
But as of right now we only know what we think we do. Which is it had no moon at all... fingers crossed they get into more detail in the future.
