According to the researchers, the phenomenon of Mercury 'transiting' through the Sun occurs only 13-14 times in 100 years. That's when Mercury appeared before the Sun, seen from Earth.
Mercury moving in front of the Sun is a rare phenomenon in the universe.
Observers must use special glasses or indirectly observe through the white plate to see the strange phenomenon.
According to calculations by astronomers, the phenomenon will occur on 11/11/2019. Time appears from 19h36 on 11/11 to 1h04 on 12/11 (according to Vietnam time frame) . However, at that time, Vietnam on the Sun's side was hidden, so it could not be observed.
In Europe and Russia, people can watch Mercury move more easily. Observing time is from 15h36 to 21h04 on 11/11 (according to Moscow time).
In addition, the areas where the phenomenon can be observed are in Africa, the Atlantic, Central America, South America and the southeast Pacific.
Mercury's next trip to the Sun will take place after 13 years, specifically on November 13, 2032.
