Hubble
is not that far away only about 600 km (370 miles)
above Earth. Its nearly circular orbit takes it once around
the planet every 97 minutes. The orbit is inclined (tilted)
to the equator at an angle of 28.5 degrees, which means that
it never travels farther north than 28.5 degrees N. latitude
(the latitude of Cape Canaveral, Florida), or farther south
than 28.5 degrees S. latitude (the approximate latitude of
Brisbane, Australia).
