If a man jumped out of the International Space Station, how long would it take him to hit the earth?
For ISS data, assume those of November 25, 2012 at 2100hrs UTC.

He would be like any other object in orbit at that height and would have to wait for the orbit to decay when he would then re-enter the atmosphere. At the height of the ISS, this would probably take somewhat less than a year.
As an example, the tool bag dropped during Shuttle mission STS-126 to the ISS took just over 8 months to re-enter.

On February 3, 2006 an empty russian space suit with batteries and a radio transmitter was pushed out of the airlock on ISS. The so-called SuitSat stayed in orbit until September 7, 2006 when it burned up on reentry over Australia.
A man would weigh a bit more than an empty spacesuit, so the tiny amount of drag wouldn't slow him down quite as much and he would stay in orbit a bit longer, but the results would be similar.
7 months.Source(s): http://en.wikipedia.org/wiki/SuitSat

I would say it would take a few months. That is, that's how long it would take for his ashes to float down to Earth. The ISS is moving at over 17,000 mph, so the speed that he jumps out is practically irrelevant (I'm assuming that he jumps at less than 170 mph). His orbit would decay from air friction, which takes about 4 to 6 months at the altitude of the ISS.

The astronauts aboard the ISS are in orbit around the Earth in simple terms like the station and all of the components and equipment aboard it. in case you leap, you could desire to possibly upload a small "delta-V" that would substitute your orbit, yet you may nevertheless be in orbit for a a lot longer time than you existence help gadget would desire to take care of you -- it is designed to be 8 hours or so.

Well, ..., he'd stay in orbit for a very long time. With nothing to slow him down, his life support would run out long before he returned to earth.

He wouldn't fall he'd stay in orbit with it. For a very long time at least.

Decades. He would be a satellite in low Earth orbit, and would gradually be slowed by atmospheric drag. At that altitude this friction is very very slight, and it would be decades before he lost orbit.

Did he jump up, or down, or parallel with the earth surface; and if parallel ,in the direction of orbit, opposite that direction, or some vector thereof?
