Features

1. The three-sphere instrument is composed of three small balls representing the sun, the earth and the moon, and has a mechanical linkage to demonstrate the relationship between the three balls and some astronomical phenomena arising therefrom. In order to imitate the real situation in nature, the sun in the middle generally uses luminous bulbs to illuminate the earth and the moon. The Earth orbits the Sun obliquely, and the Moon's orbit around the Earth intersects the Earth's orbit around the Sun at an angle.

2. The purpose of this utility model is to provide a kind of earth-moon system operation model, which can not only objectively reflect the spatial positions of the three celestial bodies of the sun, the earth and the moon, but also can intuitively and systematically demonstrate the operation of the sun, the earth and the moon. conditions, as well as various natural phenomena produced by the mutual motion of these three celestial bodies.
