Earth four-season model for solar year

Abstract

The invention discloses an earth four-season model for the solar year. The earth four-season model comprises a revolution orbit body, earth bodies and a sun body arranged outside a plane in which the revolution orbit body is positioned, wherein four earth bodies are arranged on the revolution orbit body and are respectively positioned at positions of the vernal equinox, the June solstice, the autumnal equinox and the winter solstice of the revolution orbit body; or, one earth bod is rotatably connected to the revolution orbit body; the equator of each of the earth bodies is connected with the sun body by a connecting line; the sun body is positioned on a vertical line which passes through the central point of the revolution orbit body; the connecting line is connected to a part of 165 degrees at east longitude of each of the earth bodies; and the sun body is suspended below the revolution orbit body. The earth bodies of four seasons of the vernal equinox, the June solstice, the autumnal equinox and the winter solstice and the sun body are connected by virtue of the connecting line; poses of the earth and the sun in the outer space are simulated; an earth four-season model that the sun is directly emitted to165 degrees at east longitude of the earth at nine on a dot in Beijing time is displayed; and therefore, the earth four-season model is a necessary instrument for literary researches and education on the world.

Description

technical field [0001] The invention relates to a solar year earth four seasons model. Background technique [0002] For thousands of years, Chinese astronomy has used the solar year (return year) to compile the calendar. The purpose is to provide the time basis for sowing and harvesting for agricultural production. The calendar is the "Tong Shu Lao Huang Li", which is the result of long-term measurement of the sun's shadow by ancient astronomers, and is a precious astronomical heritage of the Chinese nation. [0003] Ancient Chinese astronomers only paid attention to actual observation, ignored the rotation and revolution of the earth, did not have a return map of the sun's shadow on the earth in solar years, and failed to perfect all scientific knowledge of astronomy. The unfulfilled wishes of the predecessors must be borne by future generations. [0004] The heliocentric theory was introduced into China by Li Shanlan in 1867 when he published the book "Talking the Sky" i...
