January 14: Conjunction of the Moon and Mercury

Hello Friends of Dorian’s Secrets!

Today, January 14, 2021, the phenomenon of the conjunction of the Moon and Mercury will be occurring, which will be visible when the Sun sets in a Southwest direction.


The Moon is the only natural satellite of the Earth. With an equatorial diameter of 3476 km, it is the fifth largest satellite in the solar system, while in terms of size proportional to its planet it is the largest satellite: a quarter of the diameter of the Earth and 1/81 of its mass. After Io, it is also the second densest satellite. It is in synchronous relationship with the Earth, always showing the same face towards the planet. The visible hemisphere is marked with dark lunar seas of volcanic origin between the bright ancient mountains and the prominent astroblems.

Despite apparently being the brightest object in the sky after the Sun, its surface is actually very dark, with a reflection similar to that of coal. Its prominence in the sky and its regular cycle of phases have made the Moon an object with an important cultural influence since ancient times in language, calendar, art or mythology. The gravitational influence of the Moon produces the tides and increases the length of the day. The orbital distance of the Moon, about thirty times the diameter of the Earth, makes it appear in the sky the same size as the Sun and allows the Moon to exactly cover the Sun in total solar eclipses.

The Moon is the only celestial body in which the human being has made a manned descent. Although the Soviet Union’s Moon program was the first to reach the Moon with an unmanned spacecraft, the United States’ Apollo program conducted the only manned missions to the Earth satellite to date, beginning with the first manned lunar orbit by Apollo. 8 in 1968, and six manned lunar landings between 1969 and 1972, the first being Apollo 11 in 1969, and the last Apollo 17. These missions returned with more than 380 kg of lunar rock, which have allowed a detailed geological understanding of the origins of the Moon (it is believed to have formed 4.5 billion years ago after a major impact), the formation of its internal structure, and its subsequent history.

In 1970, the Soviet Union put the first robotic vehicle controlled from the ground on the surface: Lunojod 1. The rover was sending photographs and videos of the surface that it traveled (10 km) for almost a year.

Since the Apollo 17 mission in 1972, it has been visited only by unmanned space probes, in particular by the Soviet spacecraft Lunojod 2. Since 2004, Japan, China, India, the United States, and the European Space Agency have sent orbiters. These spacecraft have confirmed the discovery of icy water attached to the lunar regolith in craters that are in the permanent shadow zone and are located at the poles. Future manned missions to the Moon have been planned, but have not yet been launched.

The Moon remains, under the Treaty on Outer Space, free for any nation to explore for peaceful purposes.


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.

How does the Conjunction of the Moon and Mercury influence the life of the Zodiacal Signs?
