Method for measuring distance of celestial bodies

Abstract

The invention relates to a method for measuring the distance of celestial bodies. The method comprises the following steps of setting angle measuring devices for measuring angles of the celestial bodies, selecting a first measuring point and a second measuring point on the same meridian on the surface of the earth, wherein the first measuring point and the second measuring point are respectively provided with the first angle measuring device and the second angle measuring device, and the first measuring point and the second measuring point are separated with a certain latitude; aiming at the same celestial body with the two measuring points, recording measuring angles, and computing angle difference of the two measuring points (the positions of a level point and a vertical point of the celestial body on the Earth take the centre of the earth as a base point, form a diagonal line with the celestial body, and form a triangle having three straight lines and the total degree of three internal angles of 180 DEG, the angle of the centre of the Earth is utilized for computing an radiation angle of the celestial body, and the condition that the angle of the centre of the earth is measurable is utilized for solving the difficult problem that the angle of the celestial body is immeasurable); subtracting latitude distance of the two measuring points from the angle distance of the two measuring points to obtain the radiation angle of the celestial body; and taking the radius of the earth as a radix, extrapolating that the angle distance per one second equals to 1,309,778,457 kilometers, and at last dividing the distance by the radiation angle of the celestial body to obtain the distance from a measured star to the earth's core. The invention is beneficial to the development needs of space science.

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...
