From Halopedia, the Halo wiki
A planetarium lamp is a miniature planetarium projector the size of a table lamb. It is capable of displaying a planet's drifting night sky as well as those of other planets. It can also zoom into individual celestial bodies and change different colors at the switch of a dial. In 2517, Staffan Sentzke purchased one as a birthday gift for his daughter Naomi.
