Venus has spent 4.5 billion years claiming it's not like the other planets, and the evidence is now in the exosphere.
Did Venus Eat Its Own Moon?
Planetary scientists at the University of California, Riverside and the University of Bordeaux modeled the 4.5-billion-year history of a hypothetical Venusian moon and found that in most scenarios it was destroyed. Their arXiv preprint, not yet peer-reviewed, argues the moon likely spiraled inward and crashed into Venus after lasting anywhere from 30 million to 1.7 billion years, with its mass and Venus's initial spin rate the deciding variables. NASA's DAVINCI mission, launching in the next decade, could confirm it.
