Waxing gibbous or waning gibbous? The illuminated model of the Moon can display either phase, as well as the other phases of the moon. This detailed model shows the maria, terrae, ejecta, impact craters and other lunar landmark in relief. With a touch from the remote you can advance the Moon through its phases, lit by internal LED lights. It makes a great nightlight, as it will turn on in a darkened room and stay on for 30 minutes. Includes IR remote and a CD audio tour with interesting facts about the Moon. Requires 4 AA batteries and 2 AAA batteries, not included.
