Document Summary
Refractor: collects light by a glass lens. Reflector: collects light with a curved mirror: canada-france-hawaii telescope (cfht) Optical telescopes gather wavelengths that constitute light: define orbital velocity, escape velocity and geostationary. Orbital velocity just enough velocity to place a satellite that exactly balances gravity"s pull on the satellite. Escape velocity the minimum velocity needed for an object to overcome earth"s gravitational attraction. Geostationary satellite stays over the same spot all the time: name the planets in order of their distance to the sun. My very evil mother just served us nectarines. Small band of small rocky asteroids, between the terrestrial and gas giants. The kuiper belt is a thick band of icy bodies of all shapes and sizes. Celestial body that has sufficient mass for its self-gravity to overcome rigid body forced so that it assumes a nearly round shape. Is in orbit about a start, and is neither a star nor a satellite of a planet.
