The Hubble telescope located outside our atmosphere orbits around the Earth at 593 km above sea level orbital period of about 96 to 97 minutes speed _ 28,000 km/h. Its name in honor of astronomer Edwin Hubble, placed in orbit on April 24, 1990. weighs about 11000 kg cylindrical form with a 13.2 m length and a diameter of 4.2 m. Telescope can obtain images of the cosmos at >/< 0.1 arc second of resolution. http:// en.mimi.hu/astronomy/arc_second.html arc second a tiny angle unit = 1/3600th of a degree = 1/60th of an arc minute. asteroid boulder to mountain-sized piece of rock remaining from the early solar system.
