Document Summary
In mauna kea, hawaii: most well-known optical telescope in canada, the hubble space telescope (hst, orbits above earth, operates 24 hours a day. In order to insert a satellite like this into orbit around earth- you need a rocket to deliver orbital velocity. Just enough velocity to place the satellite in a position that exactly balances gravity"s pill on the satellite with the inertia on the satellite"s motion. Non-optical telescopes: the use of non-optical telescopes is sometimes called invisible astronomy , all telescopes gather energy; optical gathers wavelengths of energy b/w 400 nm and. Iau has given out official dwarf planet status to only these 5: plutoids= all dwarf planets located toward the outer regions of the solar system. Why: most scientists believe that toward the end of the planet formation period, the final few large collisions of large protoplanets/ planetesimals knocked the planets askew a bit.
