Earth moon star moving instrument

Abstract

The invention relates to an earth-moon star-moving instrument which comprises a solar body, an earth body and a moon body; the solar body is fixed on a bracket; the earth body revolves facing to the solar body and is arranged on the upper part or the lower part of the solar body; a certain horizontal distance is set between the earth body and the solar body; the moon body is arranged on a position of the earth body back on to the solar body; the earth body and the moon body all revolve around the solar body; a plane of a revolution track and a horizontal plane become an angle of 23 degrees 26 minutes, a certain vertical distance is set between the moon body and the earth body; the moon body is parallel to the plane of the revolution track and revolves around the earth body by a track with certain diameter. According to known astronomic data and astronomic phenomena, the earth-moon star-moving instrument redesigns the track of earth, ensures that people can acquaint the power source of the solar system and calculate the vertical length and the transverse length of the solar system. The earth-moon star-moving instrument is simple and reasonable in structure, low in manufacturing cost, suitable for scientific research and teaching and favorable for people to know the whole 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 tripod bracket, 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, which can be demonstrated The trajectories of the sun, the earth, and the moon and the corresponding lunar and Gregorian calendar times. When the 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 the moo...

Problems solved by technology

[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

[0018] 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
