Earth moon star moving instrument

Abstract

An instrument for simulating movement of the Sun, the Earth and the Moon comprises a sun body, an earth body and a moon body, wherein the sun body is fixedly arranged on a main support; the earth body rotates around the sun body, and is arranged above or below the sun body at a certain horizontal distance therebetween; the moon body is arranged in a position where the back of the earth body facesto the sun body; both the earth body and the moon body rotate around the sun body, and the plane of the revolution track has an included angle of 23 degrees and 26 minutes; and a certain vertical distance is set between the moon body and the earth body, and the moon body rotates around the earth body in a track with a certain diameter parallel to the revolution track plane. According to the well-known astronomical data and astronomical phenomena, the earth track is redesigned, so that people can know the power source of the solar system, and the longitudinal length and the transverse length of the solar system are calculated. The instrument has the advantages of simple and reasonable structure and low manufacture cost, and is suitable for scientific research and teaching for assisting people in knowing the entire solar system.

Description

technical field [0001] The invention relates to an astronomy teaching instrument, in particular to an earth-moon-star motion instrument. Background technique [0002] Chinese Patent Document No. CN2172508Y discloses a three-dimensional teaching aid for simulating the movement of celestial bodies, which is mainly composed of a triangular main support, a rotating frame, a power source, a metric dial, a parallel light source, the sun, the moon, the earth, a time difference dial, and a lunar calendar dial. Demonstrate the trajectories of the sun, the earth, and the moon and the corresponding lunar and Gregorian calendar times. When the operating positions of the earth, the sun, and the moon meet certain conditions, it can display total lunar eclipse, partial lunar eclipse, total solar eclipse, and partial solar eclipse. The structure is designed for the celestial body motion track explained in existing books. [0003] Human beings have grown up on the earth and have observed th...

[0007] (2) If the eight major planets have their own speeds and their orbits revolve around the sun, when the planets go to the direction of the earth towards the sun, the planets will not be visible from the earth, just like a clock, the three hands moving together There must be periodic changes. The earth sees other planets half of the time every year and cannot see the eight planets, but there is no such astronomical record

[0008] (3) According to the current diagram of the earth revolving around the sun, the exchange of the four seasons of the year cannot be explained without periodic changes between the earth and the sun

[0052] I found that the astronomical knowledge neglected the important data that the sun ray and the ecliptic formed an angle of 23°26′ long ago in ancient China when designing the earth, and only used the relationship between the equator and the ecliptic at 23°26′ in the design of the earth’s orbit, resulting in There are many places that are inconsistent with the actual astronomical phenomena
