Re: I haz a disappoint

Throwing things into the sun is a lot harder than you might think. You have to counter out (most of) the Earth's orbital speed around the sun, which is 30km/s. As a comparison, a Falcon 9 has about 5km/s of delta V, but it needs 3km/s just to get off the Earth.

It's probably just within our reach as a species to send a small satellite into the sun, but it'll have to be a small satellite either using a very efficient propulsion method (ion drive?), or some clever gravity assists.

(eg Use a close flyby of Jupiter or Saturn to send your aphelion right out to the outer solar system, and then reduce your perihelion out there where the delta V requirements are low).
