Mars retrograde instrument

Technical Field

The utility model relates to a celestial body model field especially indicates a mars retrograde motion appearance.

Background

The "retrograde" phenomenon of planets is a common and extraordinary astronomical phenomenon, common because it is visible to the naked eye and can be observed without the aid of a telescope. As early as the war of China, China has observation and record of the phenomenon of planetary retrograde motion. Particularly, the phenomenon of visual motion among planets is caused by unique celestial body orbit and planet position. Although a celestial phenomenon, human correct knowledge of it has undergone a long and tortuous historical process. Firstly, it is the important basis for Cowbini to establish that the Japanese theory overturns the geocentric theory, and at the end of the middle century in Europe, the popular official theory that the geocentric theory cannot explain the planet 'retrograde motion' phenomenon leads to an astronomical revolution, that is, the Japanese theory replaces the geocentric theory, so that the celestial motion mode that all planets rotate around the sun can perfectly explain the planet retrograde motion. Thereby opening the revolution of human understanding of the cosmology system. Secondly, the establishment of the Japanese theory has the core that science defeats the magics, fundamentally shakes the theoretical basis of the religious magics in the middle century in the western world, and plays a great promoting role in the development of natural science, and the emergence of the three laws of Kepler planetary motion later has no intimate relation with the law of Newton's universal gravitation. The importance of the strain plays a significant role in astronomy history.

The planetary retrograde motion phenomenon, the concept of a downward-looking movement, i.e., the movement of a celestial body observed from the earth with the naked eye, is explained first. Normally, planets outside the earth move slowly from west to east (corresponding to the revolution of the planet around the sun) in the star background, in addition to the east-west fall of the day (corresponding to the rotation of the earth), which is the normal movement of planets called "forward". The visual movement is also in the antegrade operation. According to the Kepler's law, the apparent orbit planes of the nine major planets are very close to each other and are basically consistent with the annual apparent orbit-ecliptic of the sun, so that the planets and their apparent motions observed by the people are near the ecliptic and are regarded as a plane, and the planets closer to the sun have shorter revolution periods, i.e. the revolution angular velocities of the planets are higher. The earth is in the inner circle of the solar system, so the running speed is higher, and the earth continuously surpasses the outer planet on the revolution orbit just like track running. Whenever the earth passes over the outer planets, the planets that were originally moving east come to a stop from apparent motion, called "stay," and then move a small amount (reverse) to the west in reverse, i.e., "reverse". The movement is seen as if the mars were reversed relative to the earth's direction of revolution. After the earth has passed the planet on its orbit, the planet appears to resume its west-to-east movement. However, the retrograde motion at the physical position of the planet does not occur, but only a visual observation phenomenon is generated due to the difference of the speed in the apparent motion. In short, the apparent movement direction of the ordinary celestial body is mostly constant, while the apparent movement direction of the planets changes periodically, i.e., sometimes forward (from west to east) and sometimes backward (from east to west) are relatively static for a while when the two directions are switched. And the forward time is long and the reverse time is short.

For the reasons, the arrangement of the planetary retrograde instrument is indispensable for astronomical science popularization venues, the explanation and explanation of the phenomenon have extremely strong science popularization value and important significance, and the historical and educational significance behind the phenomenon is self-evident. The existing model can not reflect the planetary retrograde motion phenomenon.

The phenomenon of 'retrograde motion' of the mars as the planet of the solar system closest to the earth from inside to outside is most obvious, so the mars is selected as a model sample by the development item designed and developed by people.
