How to Find Asteroids

Finding asteroids takes practice. Remember that you are looking for a yellow dot and a blue dot close together. The dots should be fairly small and bright. The yellow dot can be reddish-yellow or greenish-yellow, but the blue dot will always be dark blue. Most importantly, the two dots should be close together: no more than a few millimeters (about an eighth of an inch) apart. If two dots are more widely spaced, they are probably two separate stars, not an asteroid.
