1. The large scale of the solar system accurately depicts the relative orbital velocities of the planets as well as the relative orbital motion of Earth's Moon. 2. The EarthMoon system demonstrates the combined motion of the Moon's orbit around the Earth while the Earth orbits the Sun. 3. Crafted with fine woodwork, a twelvesided oak barrel casing, resting on solid brass feet, elegantly showcases the grand Orrery. Above the moving planets and encircling the calendar ring sits a removable armillary hemisphere made of solid brass, majestically crowning the orrery. 4. This versatile present is for any occasion: housewarming, birthdays, Valentine's Day, Mother's Day, gifts for her, and more. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
