Astronomical events in 2021
Between rare eclipses, meteor showers and the circular dance of Jupiter’s moons, as well as bright asteroids, astronomical events are numerous during the year 2021, while the closest phenomenon will be January 30 and linked to the planet Mercury.
Solar and lunar eclipses
According to the Russian news agency “Sputnik”, during the year when the sun sets in the shadow of the moon, they speak of a solar eclipse, as well as when the moon hides in the shadow of the earth around the moon, then the maximum number of eclipses will be 7 times per year.
But this is not the case now, because this year the inhabitants of Earth will have a date with two moons and two observations of the sun, the first on May 26 and the moon will be in the shadow cone of the Earth, which can be seen partly by the inhabitants of the eastern regions of Russia and completely in Australia.
The next lunar eclipse will occur on November 19, as well as the annular solar eclipse on June 10, and usually the moon’s disk overlaps the star, but this time the moon will be slightly further away, and the apparent diameter of the the disk will become smaller than the solar diameter, and the light will disappear under its edges in the form of a ring.
An annular solar eclipse will also be observed in Russia for the first time in 50 years, it will last about four minutes, and it will be partially observed everywhere except in the south of the country.
On May 26, the “giant moon” will move closer to the Moon from Earth, and the natural lunar disk will become particularly large and bright. As for the last eclipse of this year, on December 4, it will occur in the Pacific and the Atlantic. Oceans, Antarctica.
Conjugation of celestial bodies
There is one of the most interesting astronomical phenomena available for hobbyists and novices to observe the cap, when another celestial body intercepts the “conjunction”, and as a result there will be seven caps for the moon this year, as the visible disk of the moon will cover Mercury and Venus twice and Mars three times.
Astronomer Sergey Guryanov draws attention to the coverage of asteroids by stars, and the most interesting will happen on November 2, when the star Beta Aries will be blocked by the main belt asteroid (552), because the February 8, Venus and Saturn will approach each other, and they will be separated by a distance of less than half a degree.
Then, on February 11, the conjunction of Venus and Jupiter will occur, and the Sun, Earth and Jupiter will be in the same plane.
Asteroids, comets and meteors
The brightest asteroid that can be seen in 2021 is Vesta. It will reach 5.8 degrees on March 4 when it enters the constellation Leo, and will pass near Venus at a distance of 4.2 million km.
More importantly, on December 12, it will approach Earth by 0.233 astronomical units, so that those who wish can see it with the naked eye.
As astronomers note, predicting the luminosity of comets is a futile task; It happens that everything changes a hundred times and seven meteor showers will be visible from the ground.
Withdrawal of Attar and the planets
On January 24, Mercury reached its maximum stretch in the east that day at 18.6 degrees from the sun, and on January 30, it will begin to return, only to change to a morning stretch in February.
