Neptune is the windiest planet in our solar system. It appears blue due to methane gas blown across the surface. The MOVA Globe turns gently and silently inside a clear acrylic shell. No batteries or wires required! Simply place the MOVA globe on its stand, and your MOVA globe will come to life and start to turn when exposed to natural or artificial light. The MOVA Globe creates the perfect focal point for any room or office!
