Geostationary orbit ?

[Externet]

Imagine an extremely buoyant balloon rises vertically to -say stratosphere- , and stays up there; Could it be called being in a geostationary orbit ? -Ignore winds-

[YT2095]

it would certainly be geostationary, but it`s not really an Orbit.

[Externet]

And a true geostationary satellite, would not really be in orbit ?

[insane_alien]

no, a true geostationary satellite would be in orbit.

 

a balloon in the upper atmosphere however, is not in orbit anymore than you are when you're standing still.

What about when he jumps a bit?

[insane_alien]

sub orbital trajectory at best.

[Sayonara]

What if he jumps a bit facing in the opposite direction to the Earth's rotation while holding a balloon, on a trampoline?

[YT2095]

He`d look silly?

 

 

 

 

 

 

 

 

 

 

 

BUT WHAT FUN!!!

[Sayonara]

Maybe he could rub the balloon on the carpet until it acquires enough static to adhere to the firmament.

[YT2095]

actually, Joking aside, a Balloon That high up and tethered Would build up a substantial electrostatic charge.

I`v done it with a simple longwire up a tree (a makeshift SW radio antenna), and it`s quite capable of lighting a neon bulb (90v trigger voltage), or Fluorescent tubes under certain conditions.

[Sisyphus]

the opposite direction to the Earth's rotation

 

Usually we just call that "west."

the floating balloon is buoyant and geostationary in your example. Objects in geostationary orbits are falling at the same speed as they are traveling forward (for a lack of a better description).
