Shooting Something Into the Sun is HARD (www.youtube.com)

Article if you'd rather read about it.

A common joke is "just launch X into the sun and be done with it". Turns out, that's actually a really difficult thing to do.

From Earth, we would have to accelerate a spacecraft to 33 m/s in the opposite direction of our orbit in order to get it to fall into the sun (without entering an elliptical orbit) For reference, we only need to launch a spacecraft at 11 km/s in the same direction of our orbit to cause the spacecraft to escape our solar system.

This means that it would take less energy to launch a spacecraft to another star than our own sun.

Also, nuclear fuel is not renewable. There is a finite amount.

Imagine future generations hearing about the idiots who wanted to throw the barely used uranium into the sun.

The "what" gets shot into the sun is less important, lol. I just found it interesting that shooting anything into our sun is more difficult than sending it to another sun.

I know and it's an interesting video. It's just that I've seen that suggestion posted seriously more often than it should be.
