Maybe this should be in Nostupidquestions as I'm aware the moon exists. And I guess there may be an orbit zone where things tend to remain in orbit. But curious...

The full context question is: For man-made satellites, would they benefit by having a "Self destruct" button?

Sure it may add more debris but since an explosion would scatter debris in all directions, anything flung up or down would cause it to get out of this geostationary zone/band.. And hopefully come crashing down to Earth, reducing overall debris? Compared to an abandoned satellite, remaining in orbit and breaking down due to relatively low energy collisions with surrounding debris.

Basically I'm trying to justify self destruct buttons. Thank you!

The amount of space between planets is crazy. My old school had a scale model of the solar system using the same scale for size and distance.

On one end of campus there was a 12" yellow sun. Around campus were poles with little domes on top that had little pins with plant models suck in them.

Hmm, looks like there's actually several of these at universities. I have heard about them.

Wikipedia has a list. There's even more than one that incorporates Alpha Centauri, although one cheats by using a full trip around the Earth (the other one is in Finland and places Proxima in Australia).

My school was usa east coast. We had our Oort cloud at a school in europe.

That's also cool. How is it represented?

Not sure I I've never seen it. I think was just a bit of text on a wall.
