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...
The different types of orbits are: 1)Low Earth Orbits:This orbit is high enough to miss all the mountains and also high enough that the atmospheric drag won't bring it right back to the surface. ISS follows a Low Earth Orbit. 2)Highly Elliptical Orbits: Perigee is the closest point and apogee is the farthest point from earth..
