What is the number of 13 constellation?

In fact, the thirteenth constellation is called Ophiuchus, because a British astronomer observed the changes of the stars and found that there were always some errors in the time of year. If it is longer, the time error will be bigger and bigger, so a new constellation "Ophiuchus" will be added between Scorpio and Sagittarius, which will become the thirteenth constellation we are talking about today. The real constellation dates should be listed as follows: Aries April 19-May 13 Taurus May14-June 20 Gemini June 21-July 19 Cancer July 20-August19 Leo. 1October 30th Libra 65438+1October 3rd1/kloc-0+1October 22nd Scorpio 65438+1October 23rd-65438+/. +1 October 65438 +08 Capricorn 65438+1October 65438+09-February 15 Aquarius February16-March1Pisces March1March.
