I asked Alan Case, award-winning flight shooter and math wizard, this question:

Given a planet of the same average density as ours, with no atmosphere, what diameter would it have to be in order for someone to shoot an arrow 170fps/116mph  and have it circle the planet, such that they could turn around and catch it? and how long would that near ground level orbit it take  This will be the hot new sport of the next century.

His answer:I’m assuming the orbit will have an altitude close to the surface and the planet is spherical in shape.  For the arrow traveling at 116 mph, the diameter of the planet is 51.2 miles, and the time to complete one orbit is 84-1/2 minutes.

  He then added:The Moon of Jupiter, Enceladus, is almost perfect for the arrow shot. The density is very low at 1.609, but the larger diameter gives it enough mass that it has a 175 ft/s orbital velocity at its surface. It is also nice and spherical in shape. He added: " I can’t wait for the first archery range to open on Enceladus!"

I informed Alan that lots on Enceladus would be for sale as soon as possible, discounted for archery folks, a well designed set of archery laws embedded in all deeds, and that in gratitude for his help he should be given two choice lots right near the range.

Anyone interested in purchasing near or adjoining lots please contact the appropriate agent.

Meanwhile The Enceladus Planning Commission is seeking suggestions for archery contests, games and demonstrations appropriate for this near zero gravity planet. Post your submissions here and they will be forwarded.

I don't even like leaving the county any longer. I'm going to have to pass, but it does sound like fun.

I got all I can do to kill these WV deer

I can barely hit the target at 40 yards and you expect to be able to catch the arrow after 161 miles? You much be using a sight.

I'd like them to shoot arrows on the moon. I'd supply the bow and arrows. I took this photo through my telescope.

Did he do the math in his head?

Nice to hear from you Tim.

I think those lots would have to encircle that globe to avoid having an arrow pass through someone else's airless space...

I'll bet Alan could do the math on why the centerline of the Golden Gate Bridge piers is 1.5" wider at the top than at sea level. haha

I thought about this for a while. My vision blurred and hands started to sweat, so I am gonna just walk away. I just didn't do that well at Story problems either. Fifth grade was tough.

Tim, you're a boss! This is awesome. and Buzz, great pic! Yes... I'm a total scifi geek :) I'm booking my seat today- got a call into Elon.

So...if you miss your back stop you could shoot yourself in the back side? And that's supposed to be a good thing?

Theoretically what if you punctured a hole in your very shallow skinned space craft? Pretty sure there will still be some gravitation drop in flight.

Too far out there! But recently saw a video of a guy shooting a compound underwater. Wonder how depth affects spine.

Good to hear from you, Tim.

If you don't pay close attention to the time as you are waiting for the arrow to circumnavigate Encaladus, the arrow could end up in Uranus.

Thats funny - I don't care who you are thats funny.

Yes Alan could probably do the math in his head.’and catch the arrow with his foot! You had to be there to understand the foot part. ??????

Good one, Tim. You always had a penchant for these kinds of problems. Jawge

A penchant, I thought that was something your wife hung on her blouse.

I would love to go but, I am busy working on the high speed rail project from LA to Hawaii. bvd

You'd have to practice Shaolin Kung Fu like Kwai Chang Caine to catch the arrow.

I just shot the old cow jumping over the moon.

From: Tim Baker

Kokosing,   Are you reporting back from the future?  If Enceladus does itself have a moon, then a cow, properly outfitted with a cow- shaped pressurized suit and breathing gear, very well could jump over the moon. Gotta say, orbiting barn animals would be tempting targets.
