(Cries in Rich Hall)
Explaining the joke
Rich Hall made frequent appearances on QI and one of the questions they always prepare for him is “How many moons does Earth have?”. Since we’re always discovering quasi moons and transient bodies, the answer is always different despite him learning from his previous appearance.
One… It’s called the MOON!!!
Yeah, a quasi-moon doesn’t even orbit the earth, it’s just orbiting the sun on a similar plane an happens to be nearby. But due to it’s small mass, it cant stay for too long before it’s flung out again. It’s only the Earth’s gravity that’s keeping it around a little longer than usual, typically, anyway. There’s lots of types and thus lots of scenarios.
Yeah you’re correct. My comment was referring to the same segment on qi was in which my comment was called out when they claimed there were 2 moons. Depending on the exact episode you watch they state 1, 2, “many” or 0 moons of earth.
