Phobos is an Exceptionally Dark Object in the Solar System

AI Thread Summary
Phobos, one of the darkest objects in the solar system, is notably small compared to Mars, with an escape velocity of approximately 11.5 m/s, making it theoretically possible for a sprinter to launch themselves into space. The discussion humorously explores the idea of using Phobos as a launching point for activities like throwing baseballs at Mars or biking towards its surface. Participants express fascination with the moon's characteristics and potential future significance if Mars becomes inhabited. The conversation also touches on the notion that Phobos may be a captured asteroid. Overall, the thread combines scientific insights with playful speculation about Phobos and its relationship with Mars.

funny, since Phobos is "one of the darkest objects in the solar system"!

i never realized how tiny phobos was compared to mars!

In principle, a person could run and jump off of this tiny moon. I think the escape velocity is about 3m/s.
 
mmmm I just want to put some bacon and chedder cheese in that moon and eat it

Unprotected you would die first. It would probably be easier to just jump straight.

Very interesting Ivan; however, the escape velocity of Phobos is about 11.5 m/sec, so you couldn't jump straight up. I can't run that fast but a good sprinter could and thus, running off an appropriately positioned cliff, he could launch himself into space. That's about 26 mph; so I could probably ride a bicycle into space;...well, at least I could throw baseballs into space.

It is quite amazing to realize that I could stand on a Martian moon and I could terrorize the Martian surface by pelting it with appropriately directed baseballs as often as I wish. It would be interesting to figure the enourmous increase in energy by which my feeble baseballs would decsimate the surface of Mars. (Assuming I could keep my baseballs from burning up in the Martian atmosphere). Or I could take a free ride on my bicycle in in a chosen direction such that I will end up on the surface of Mars (with quite an impact I might add)!

It makes me think that Phobos may one day be a very stategic place if Mars ever becomes inhabited.
Just a thought.:wink:

P.S. Thanks Phobos for the appetizing images.

How about Deimos? I remember 3m/s for something. Still, what a concept eh?
 
More on this utterly fascinating little world...:wink:

Kerrie - - yep, likely just a captured asteroid

Creator - - (re: biking to Mars) Just use airbags like NASA does!

He, He; good point; maybe I'll give it a try.
