The sheer number of objects suggests scientists will soon have to grapple with what counts as a moon versus what’s just a large rock

Saturn just solidified its title as ‘moon king’ with an updated tally of 274 satellites orbiting the gas giant. The record-breaking statistic puts Saturn way ahead of its moon-bearing competitors, as now the ringed planet is officially orbited by almost twice as many moons as all other planets in the solar system combined.

The discovery points to what astronomers have thought for decades, that Saturn's rings were caused by a massive collision about 100 million years ago.
