February 8: Mercury in lower conjunction with the Sun

Hello Friends of Dorian’s Secrets!

Today, February 8, 2021, the phenomenon will be occurring in which Mercury will be in lower conjunction with the Sun.

This will be happening at 14:00 UTC, at which time Mercury will no longer be visible during sunsets and will pass into the morning sky.


Mercury is the planet in the solar system closest to the Sun and the smallest. It is part of the so-called interior or terrestrial planets and lacks natural satellites like Venus. Very little was known about its surface until the Mariner 10 planetary probe was sent and observations were made with radar and radio telescopes. It was later studied by NASA’s MESSENGER probe and currently the European Space Agency (ESA) spacecraft called BepiColombo, launched in October 2018, is in flight to Mercury where it will arrive in 2025 and is expected to provide new knowledge about the origin and composition of the planet, as well as its geology and magnetic field.

Formerly it was thought that Mercury always presented the same face to the Sun (captured rotation), a situation similar to the case of the Moon with the Earth; in other words, their rotation period was equal to their translation period, both of 88 days. However, in 1965 radar pulses were sent towards Mercury, with which it was definitely demonstrated that its rotation period was 58.7 days, which is 2/3 of its translation period. This is not a coincidence, and it is a situation called orbital resonance.

Being a planet whose orbit is lower than that of the Earth, we observe it periodically passing in front of the Sun, a phenomenon called astronomical transit. Observations of its orbit over many years showed that the perihelion rotates 43 ″ of an arc more per century than predicted by classical Newtonian mechanics. This discrepancy led a French astronomer, Urbain Le Verrier, to think that there was a planet even closer to the Sun, which they called Vulcan, which disturbed the orbit of Mercury. Now it is known that Vulcan does not exist; the correct explanation for the perihelion behavior of Mercury is found in Einstein’s general theory of relativity.


The Sun (from the Latin sun, solis, “sun god invictus” or “sun”, Helios in Greek mythology, in turn from the Proto-Indo-European root sauel-, “to shine”) is a G-type star of the main sequence and luminosity class V which is found in the center of the solar system and constitutes the largest source of electromagnetic radiation in this planetary system. It is an almost perfect sphere of plasma, with an internal convective movement that generates a magnetic field through a dynamo process. About three-quarters of the Sun’s mass consists of hydrogen; the rest is mostly helium, with much smaller amounts of the elements, including oxygen, carbon, neon, and iron.

It was formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter accumulated in the center, while the rest flattened into an orbiting disk that became the solar system. The central mass became increasingly dense and hot, eventually leading to nuclear fusion at its core. It is believed that almost all stars are formed by this process. The Sun is roughly intermediate in age and has not changed dramatically for more than four billion years, and will remain fairly stable for another five billion years. However, after the fusion of hydrogen in its core has stopped, the Sun will undergo major changes and turn into a red giant. It is estimated that the Sun will become large enough to engulf the current orbits of Mercury, Venus and possibly Earth.

Earth and other bodies (including other planets, asteroids, meteoroids, comets, and dust) orbit the Sun.

By itself, it represents about 99.86% of the mass of the solar system. The mean distance from the Sun to the Earth was exactly defined by the International Astronomical Union as 149,597,870,700 meters (approximately 150 million kilometers). Its light travels this distance in 8 minutes and 20 seconds.

Energy from the Sun, in the form of sunlight, sustains nearly all life on Earth through photosynthesis, and determines Earth’s climate and meteorology.

It is the star of the planetary system in which the Earth is located; therefore, it is the star with the greatest apparent brightness. Their visibility in the local sky determines, respectively, day and night in different regions of different planets. On Earth, the energy radiated by the Sun is used by photosynthetic beings that constitute the base of the food chain, thus being the main source of energy for life. It also provides the energy that keeps climate processes running.

The Sun is a star that is in the phase called main sequence, with a spectral type G2 and luminosity class V, therefore, it is also called a yellow dwarf, it was formed between 4567.9 and 4570.1 million years and it will remain in the main sequence for approximately 5 billion more years. The Sun, together with all the celestial bodies that orbit around it, including the Earth, make up the solar system.

Despite being a dwarf star, it is the only one whose shape can be seen with the naked eye, with an angular diameter of 32′35 ″ of arc at perihelion and 31′31 ″ at aphelion, which gives an average diameter of 32′03 ″. The combination of sizes and distances of the Sun and the Moon are such that they are seen with approximately the same apparent size in the sky. This allows for a wide range of different solar eclipses (total, annular, or partial).

The vast effect of the Sun on Earth has been recognized since prehistoric times and has been regarded by some cultures as a deity. The movement of the Earth around the Sun is the basis of the solar calendar, which is the predominant calendar in use today.

The scientific discipline that is responsible for the study of the Sun in its entirety is solar physics.

How does the phenomenon of Mercury in lower conjunction with the Sun influence the life of the Zodiacal Signs?
