The best way to tell what type of siding is on your home, is to go to an unfinished area like the attic or garage, and pull back the tar paper from the back of the siding and look for markings. See if you can locate either the manufacturerâs name or AHA code (The American Hardboard Association).
The International Space Station (ISS) flies around the earth in a near circular orbit. The current altitude for that orbit is somewhere around 250 nautical miles. Given that altitude, the period, or time for one orbit is approximately 90 minutes...
High Earth Orbit. When a satellite reaches exactly 42,164 kilometers from the center of the Earth (about 36,000 kilometers from Earthâs surface), it enters a sort of âsweet spotâ in which its orbit matches Earthâs rotation.his special, high Earth orbit is called geosynchronous. A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground. It is always directly over the same place on the Earthâs surface.
