A tiny detail on a kid’s solar system poster starts off a cosmic query about our place in the universe.

As co-host Latif Nasser was putting his kid to bed one night, he noticed something weird on a solar system poster up on the wall: Venus had a moon called … Zoozve. But when he called NASA to ask them about it, they had never heard of Zoozve, and besides that, they insisted that Venus doesn’t have any moons. So begins a tiny mystery that leads to a newly discovered kind of object in our solar system, one that is simultaneously a moon, but also not a moon, and one that waltzes its way into asking one of the most profound questions about our universe: How predictable is it, really? And what does that mean for our place in it?
