A lottery of the time and position of orbital falls. No odds just the sheer number of guesses multiplied by a $. More than one entry per lodger is allowed but must be unique.

If two guesses are equal, because this is an internet, world wide game, another decimal place will be requested. Lodger can choose time , latitude or longitude until a difference is generated.

Closest wins. Just don't stand at your guess at the wrong time.

If actual impact area is found to be not measurable to enough accuracy, a random generator is used to differentiate the closest lodgers to one single winner.

You can already bet on the likelyhood of any event.

Surely the likelihood of any event is 1, and so no bookie would take that bet?

...and you'll be incentivising people to knock satellites out of orbit just to win money

But you'll also incentivize people to study physics, fluid dynamics, and orbital mechanics. Which they'll need to knock satellites out of orbit.

Yes, a great way to get people to study physics
