Our planetary orbit clock is in perpetual motion with blue and silver spheres rotating in orbit while suspended in air on circular metal wires. Read the time like a classic clock from above with the space view of the earth and numerical clock face. Little metal planets orbit a larger central planet at the middle of the “universe.” One planet signifies hours, another minutes, and the last tiny planet is the second hand. A delightful conversation piece for any desk or countertop. Requires one “AA” battery, not included.
