The large scale solar system model shows the correct relative orbital velocities of the planets and the Moon’s motion around the Earth, helping users understand how the Moon traverses in step with the Earth’s orbit around the Sun. The Earth’s lunar system demonstrates the composite motion of the Moon orbiting the Earth as the Earth itself orbits the Sun, providing a clear visualization of celestial dynamics. Crafted in fine wood, the orrery sits in a twelve-sided oak barrel housing on solid brass feet, offering a sturdy and elegant display. Around the moving planets and above the calendar ring is a removable armillery hemisphere made of solid brass, which crowns the great orrery with a refined, traditional look.
