Sun and Zodiac Signs of 2020


Year of the Silver Rat - 2020 The moments of the transition of the Sun from one zodiac sign to another is determined by the time of alignment of the geometric center of the star with an ecliptic longitude multiple of 30°.
These dates are not consistent with the Earth's daily cycle and vary from year to year, due to the fact that the duration of the astronomical year is not equal to the whole number of days (365,256 days), as well as the fact that the Earth and the Moon, when rotating around the Sun, are a binary system, the center whose mass does not coincide with the center of the earth.

To determine the moments of these events, a table has been compiled, in which their exact date is given.* - the number, month and time of the entry of the Sun into the zodiac signs for 2020.

Sun and the zodiac Constellations in 2020

Until the final approval of the constellation boundaries by the International Astronomical Union at the 1935 General Assembly, the table presented on this page simply could not exist, because previously the constellations did not have clearly defined boundaries

he Culmination of the zodiacal Constellations in 2020

The zodiac constellations are by no means lined up along the ecliptic in a strict line, therefore, two constellations can often fall into the culmination area, therefore, two dates are given in the table - the start and end dates of the culmination of each constellation..

Sun, zodiac constellations and zodiac signs summary table

It is necessary to distinguish between the concepts of the stay of the Sun in the Signs of the zodiac and its stay in the same zodiac constellations - this is far from the same thing.

Zodiac signs - this is just a well-established since ancient times, the designation of conditional 30° sectors of the celestial sphere (All the mystery of such a division of the celestial sphere would be lost if the sector would just be numbered. Imagine: instead of dialogue: - "What sign were you born under?" - " lion", - would sound: " In what sector was the Sun at the time of Your birth?" - " in the fifth!":) .

Constellations, on the other hand, are certain sections of the celestial sphere whose boundaries are now clearly defined, agreed upon and accepted as the basis for orientation by the celestial sphere by astronomers of the whole world. The time of the observed passage of the sun, within the boundaries of a particular constellation, is called the time it was in the constellation. The boundaries of the zodiac constellations and zodiac sectors do not coincide at all (although at the beginning of our era, 2000 years ago, they were close to each other). In the table below, the average dates of the Sun's stay in the zodiac sectors (zodiac signs) and zodiac constellations are presented.

* Modern official astronomy has long ceased to be involved in calculating the visual movement of the Sun across the zodiac sectors, so I believe that the accuracy of the interpolation formulas I have chosen is ± 2-3 minutes.
