In mid-July, the new moon is chasing the inner planet Venus and the outer planet Mars, which are closest to the earth, from west to east (white road, the path of the moon). At 17:00 on July 12, the moon caught up with Venus, which was on the south side of the crescent moon, and the distance between the two was about 3 degrees; at 18:00, the moon caught up with Mars, and Mars was on the south side of the crescent moon, and the distance between the two was about 4 degrees. At 14:00 on July 13th, the crescent moon will catch up with the brightest star “Xuanyuan Fourteen” in Leo. “Xuanyuan Fourteen” is on the south side of the moon, and the distance between the two is about 5 degrees. At 15:00, Venus will catch up with Mars from west to east , Mars is south of Venus, and the distance between the two is about 0.5 degrees. Venus and Mars are so close together, it is very rare. If the “super moon” moves in front of Venus and Mars at this time, it can cover both at the same time.
Among the three stars, Venus is the brightest, with an apparent magnitude of minus 3.9, which is the brightest celestial body except the sun and moon; Mars is the darkest, with an apparent magnitude of 1.8, which is the brightest star than Ursa Minor.” “Polaris” (apparent magnitude 2.0) is slightly brighter; “Xuanyuan Fourteen” has an apparent magnitude 1.4, which is brighter than Mars.
Twenty minutes after sunset, all parts of China can be observed to observe the low altitude north of the west. On July 12, the sunset in Guangzhou was 19:16, that is, Guangzhou can be observed at 19:36. The moon and Venus can be seen first, and then “Xuanyuan Fourteen” and Mars can be seen. Since the Samsung Moon Moon appears in the low altitude, the atmosphere is thicker or the cloud cover is slightly more, it is better to observe Mars and “Xuanyuan Fourteen” with the help of binoculars.
