Measuring method of star distance

Abstract

The invention provides a measuring method of star distance, comprising the following steps: installing an angle measuring device which is used for measuring the angle of star; selecting a first measuring point and a second measuring point which are separated by a certain latitude on the same meridian line on the earth surface and which are respectively arranged with a first and a second angle measuring devices; aligning the same star from the two measuring points, recording the measuring angles and calculating the difference of the measuring angles of the two measuring points; obtaining the angle difference of the star by the difference of the measuring angles of the two measuring points minus the latitude difference of the distance between the two measuring points; taking the radius of the earth as the base number, calculating that one second angle difference=360*60*60 / 2pi*6350km=1.309.778.457km is approximately equal to 8.732 astronomical units; finally obtaining the distance between the measured star and the earth center through dividing the one second angle difference by the star angle difference. The invention adopts the angle change law of the round and triangle to calculate the star angle difference with the triangles generated by the two angle measuring devices and the star and by the inner earth and the two measuring angle measuring devices on the ground surface.

Description

technical field [0001] The invention relates to a method for measuring distances of stars. Background technique [0002] The size of the universe has been a research topic in astronomy for hundreds of years. Scientists use a variety of methods to measure it, including the Cepheid cycle-light relationship distance measurement method, spectrometry method, and triangular parallax method. However, there is no reference object in the sky as a basis. Only God knows the accuracy of the measured distances. The results of each measurement are different. If the distance of each star cannot be accurately recorded, there will be no basis for space exploration. Accurate measurement of planets has become a worldwide problem in astronomy. [0003] Now astronomy uses the method of triangular parallax to measure the distance of stars, that is, to measure and record the angle of the stars first, and then to measure and record the angle of the stars for the second time after 6 months, using th...
