Where and when can I observe Scorpio?

To determine the location of Scorpio, we only need to establish a spherical coordinate system and know its angle θ with the X axis and φ with the Y axis.

The constellations in the sky run according to certain rules, rising in the east and setting in the west. It takes 24 hours and 4 minutes for a star to appear in the same position the day before. /kloc-the sun is in Scorpio in October/February, that is, Scorpio can't be seen in/kloc-October/February. Let's think about it from another angle. Is it in June that the sun is just facing Scorpio, so in the afternoon 12, when you look at Scorpio, the elevation angle is the largest? At this time θ = 90. So you can deduce the general orientation θ of Scorpio at any time according to the above-mentioned laws of star motion.

Scorpio is one of the zodiac signs, so he is on the ecliptic plane, which is 23 degrees and 26 minutes away from the equator. As long as you know your latitude, you can calculate the angle between the line of sight and the polar axis when observing Scorpio. That's φ.

So you can determine the location of Scorpio.

To sum up, you can see Scorpio around summer. Location, as long as there are no unsightly buildings around at this time.

PS: To find Scorpio, first find a bright star, such as Antares, and then find all the constellations through their relative positions. If the environment is good, look directly. If the environment is poor, you can consider using binoculars to find constellations. The effect is good!
