Determinarea valorii unității astronomice din observațiile tranzitului planetei Mercur

Abstract

For the first time, the transit of Mercury was predicted by the German astronomer Johannes Kepler, and Edmond Halley proposed that the observations of the transit of Mercury and Venus planets to be used to determine the value of the astronomical unit. The paper presents the results of observing the transit of the planet Mercury at the Astronomical Observatory of the Technical University of Moldova which took place on November 11, 2019 and describes the methodology for determining the value of the astronomical unit from the results of observing this transit.
