I don't think you would get any significant thrust from them on Diemos. The max surface temperature is -4 C (https://solarsystem.nasa.gov/moons/mars-moons/phobos/in-depth/). The boiling point of butane is -2 C (https://www.gasit.co.uk/support/knowledgebase.php?article=59). I don't think the can would really spray at that temperature, and -4 C is a light side ...

Deimos: Radius 6.2 km, Mass 1.47e15kg. Let's pick an initial circular orbit radius at a safe 8km. Orbital velocity calculator gives 3.502m/s orbital velocity. To deorbit, we'd need to drop periapsis to ~6km so the same calculator gives us 3.242m/s for apoapsis of 8km and periapsis of 6. (lithobraking by digging boots into the surface at 3m/s should be enough ...

I understand I am (3 years) late to the party, but I was recently linked to this question and figured I could determine a pretty accurate way to answer question 2 of 3 (how far from Earth at separation). I know the question asks for "roughly" how far but I have seen many of OP's questions looking for far greater detail on other topics so I am ...
