Explanation: There are many shining "double stars" in Leo and Little Lion. For example, one of the vertices of the Spring Triangle, the bright star "Tianjin IV (β Leo)" located at the tail of Leo, is only about 36 light years away from us. Although it looks like a beautiful blue-orange visual binary star from the earth, in fact the two stars are far apart. Let's start with the lion's gamma star, which is located in the lion's chest. It is a golden binary system with brightness of 2.2 and 3.5 magnitude, respectively, and orbits each other for about 6 19 years. And the lion ζ star in the northwest of the lion γ star, which is also a bright binary star. These binary stars can be easily distinguished by binoculars or small telescopes. In Leo, CP 1 133 (the lower left corner of the above picture) is one of the four waves discovered by Jocelyn Bell Burnell and antony hewish in 1968, and it is also the object of value appreciation.
