It looks like a potato that could be cut up into french fries with a cheeseburger order.

Like a grain of sand, been polished by millions of collisions?

[Larry Lucido]

12.5 km average circumference. Good place to practice running a half marathon. Might need extra oxygen.

[VTenigma]

Bring your own gravity.

It might be small enough to launch yourself into orbit with a long jump.

Deimos’s escape velocity is only 5.8 m/s. A stone dropped from waist height would take around 30 seconds to reach the ground.

[Alas Babylon!]

Land on it with robotic mining equipment, hollow it out, put windows on those bigger craters and a rocket on the back.

Space motor home.

Deimos’s escape velocity is only 5.8 m/s.

You could throw rocks from Deimos have them fall on Mars. Hint: throw them in the direction Deimos came from.

Mmmmmmm . . . cheeseburger and fries . . .

Oh great. Now I’m going to have to go grab some grub because I can’t cook worth squat. :-)

[blueunicorn6]

I always knew that deep down inside, you love cheeseburgers, too.

Hillbilly space motor home.

This was an early attempt at bowling balls. The finger holes weren’t deep enough, and the triagular shape made the ball very unpredictable.

Live and learn.

How did Jonathan Swift predict mars moon speeds?

My first encounter with this was here:

Captured asteroids?

The USNO’s 26” refractor telescope was used to discover those two moons. I wonder if the current resident has even bothered to look thru it. I would love to be vice president just to live on the grounds and look through that beast.

There was a sci fi story where explorers found the third moon that was at such a low altitude that it cut through mountains.

Three moons

Looks like cheese.

Deimos’s escape velocity is only 5.8 m/s.

Its orbital velocity would then be 5.8 m/2 divided by the square root of 2.

So, about 4.1 m/s. Or roughly 10 miles per hour.

Doable.
