Place a satellite in a circular orbit about 42,000 kilometers from the center of
the Earth (36,000 kilometers or so from the surface) and it will orbit once in
24 hours. Since it matches the Earth's rotational period, it is known as
a geosynchronous orbit. If that orbit is on the plane of the equator, the
satellite will hang in the sky over a fixed location in geostationary orbit.
As predicted in the 1940's by futurist Arthur C. Clarke,
geostationary orbits are commonly used for communication and weather satellites.
Images of the night sky made with telescopes that follow the stars can also pick
up geostationary satellites gleaming in the sunlight still shining far above Earth's
surface. Because they all move with the Earth's rotation against the background
of stars, the satellites leave trails that seem to follow a highway across the celestial
Progress made on the back! Hand-beading is on it's way
toward completion, and I have a good idea of how I will finish
the construction of this piece... keep a look out!
I think it will be pretty cool when it's finished up!
