At 15:11 on July 4th, Beijing time, the earth passed its orbital aphelion, which is the moment when the earth is the farthest from the sun in a year.
Therefore, the apparent diameter of the sun is also the smallest in a year, which is the so-called "smallest sun".
[Explanation] Experts remind that people who want to watch the "minimum sun" must pay attention to the protection of their eyes and do not observe it directly with the naked eye.

Although it is the "smallest sun" in the year, we should also pay attention to protecting our eyes when observing. Interested astronomers can use telescopes with light-reduction devices such as Bard's film to observe.
[Commentary] The "mini" sun ends, and the "giant" moon debuts.
This month's heavy celestial phenomenon - the annual "biggest full moon" will appear in Tianyu at 2:38 on the 14th, Beijing time.

Since the moment of the full moon appears in the early morning of the 14th, we can observe the beauty of a bright moon in the sky in advance on the evening of the 13th.
[Commentary] This month's planetary show is also a good show, with Mars and Venus appearing one after another, and "hand in hand" with Moon Girl to bring wonderful performances.
In the summer night sky in the northern hemisphere, the meteor shower is occasionally late, but not absent.
On July 30, the Delta Aquarius Southern Meteor Shower ushered in a maximum, with a maximum zenith flow of 25 per hour.
Typically, the shower's active period lasts from July 12 to August 23, and shower enthusiasts can look forward to it.
