Ready, Jet, Go!

SINOPSIS

The kids are using Sean's telescope to look at two asteroids in the night sky and notice that one is brighter than the other. Mindy guesses that the brighter one is covered in glitter. Jet thinks maybe it's made up of mirrors. Sean reminds them that most asteroids are like "chunky rocks," so it probably has nothing to do with glitter or mirrors. They ask Dr. Rafferty, and she explains about albedo, the reflectivity of an object.
