===Discovering Asteroids===

Discovering asteroids is easily done because of their large proper motion|proper motions, the key to discovering near-earth objects.  An object orbiting the sun in the asteroid belt between Mars and Jupiter will typically move about 10 seconds of arc over a 15-minute period. Near-earth objects will have larger proper motions both because they are closer to the earth and because, being closer to the sun, they have larger orbital velocity|orbital velocities.  Generally, the closer the asteroid to the earth, the brighter it is and the greater its angular distance of movement between observations.
