Earthlings, it is possible to see Mercury with the naked eye on Wednesday morning.
This is because Mercury's position is at the point of orbit with the Sun, aka perihelion. On the other hand, the planet is also in a trajectory close to Earth.
Revealed that this was due to the elliptical orbital path with the Sun.
"Mercury's perihelion occurs every 88 days on average or four times a year,"
Mercury's perihelion will occur on October 20, 2021. When this natural event occurred, Mercury was 46 million km from the Sun. Mercury's previous perihelion has occurred on January 29, April 27, and July 24, 2021. This means that this Mercury Perihelion will be the last to occur this year.
Mercury's next Perihelion will take place on January 16, April 14, July 11, and October 7, 2022.
When it is perihelion, Mercury will receive twice as much energy as when it is in aphelion.
The angular width of Mercury when observed from Earth when perihelion is 26.6% greater than aphelion, although the difference is not so significant when observed through a telescope because the angular width of Mercury varies between 0.106-0.134 arc minute
In which direction to see Mercury?
Mercury can be observed at the beginning of the nautical dawn from the east-southeast direction near the constellation Virgo for 20 minutes. Mercury's magnitude varies between +0.47 to +0.46
