In the solar system,Mercury is the most difficult of the five planets to observe because it is too close to the sun.

In general,

According to domestic media reports, according to astronomical experts,On March 6, 2021, the second and the first large-distance Mercury will be staged in Tianyu.

At about 5:00 a.m. on the 6th, if the weather is fine, the public can find a place with a wide field of vision, facing Southeast and low altitude, and first find Jupiter with a brightness of - 2.0, which is more obvious and easy to identify.

Then take Jupiter as the navigation, and not far from the lower left side of Jupiter is mercury with brightness of 0.1. It will be easier to see it with binoculars or small telescopes.

In addition, on March 5, mercury and Jupiter are closest, and the distance between them is less than 0.5 degrees (the apparent diameter of the full moon), which is also worth seeing.

It is understood that,

Mercury is the smallest and closest planet in the solar system. The orbital period is 87.9691 days, and it will meet with the earth once in 116 days. The orbit speed is far faster than other planets in the solar system.

Mercury does not change in four seasons, and only it resonates with the orbit of the sun. The time for every three rotations is almost equal to the time for two rotations around the sun. Looking at mercury from the sun, according to its rotation and revolution, there is only one solar day every two mercury years.
