Actually, if you jump up into the air you are in orbit around the center of the earth. Unfortunately, the perigee (lowest point) of your orbit is not far enough away from the center of the Earth to prevent you from impacting with the surface of the Earth.
Absolutely awesome. I live in a [relatively large] house with two other families, and I have six children. There are 14 people under the age of 18 in our house. I love opportunities to play with their minds.
So the next time I'm jump roping on the front porch, I can tell them that I'm not exercising, I'm attempting to maintain orbit.
If I remember correctly, I'll have to get to 22,000 miles of elevation to maintain geosynchronous orbit and land back on my front porch rather than someplace dangerous or far from home. It will take a few years, I think, to work up to that high of a jump
. Besides, I don't want to maintain orbit, but return to earth, so I'm going to have to figure out how high to go and how much atmospheric drag to account for. I know my basic orbiting speed is close to 800 MPH, but I'll have to get that exact, too.
Or, maybe I can just get it right the way I would catching a baseball, intuitively with practice.
Maybe I better get back to work and stop wasting my time and everyone else's
.
My kids will love that discussion, though. I'll bet the teenagers will keep it going for hours and actually go look up information on orbits.
