8. 19 What time is Gobang?

This five-star gobang can be seen in most parts of China, but only if the weather is fine. Hunan, Fujian, Jiangxi, Guangxi, Guangdong, Heilongjiang, Jilin, Liaoning and other places can be seen. Henan, Fujian and Jiangxi have a high probability of moderate to moderate rain, and there is heavy rain in some places, which may not be seen.

From an astronomical point of view, the occurrence of five-star renju is well explained. It takes about 88 days for Mercury to make a revolution, 225 days for Venus, 687 days for Mars, 4333 days for Jupiter and 10760 days for Saturn. As long as we find the least common multiple of these numbers, it is the number of days required for five-star gobang.

This figure is truly astronomical. Fortunately, the ancients did not have high requirements for five-star alignment. As long as the longitude difference between the five planets does not exceed 30 degrees, or even 45 degrees, it is considered to be five-star alignment. Under such conditions, it is much easier to have a five-star phenomenon.
