Constellation, Snake
This is a sign of Ophiuchus. The constellation symbol shows that a wavy stripe is also depicted on a letter "U". It should be noted that, in Google platform, the background frame of icon is green, while the background frame adopted by most other platforms is purple or purple-red, and some platforms focus on describing constellation symbols themselves, without extra design of background frame. As for the colors of constellation symbols, they vary from platform to platform, including white, purple, orange and black.
Ophiuchus is an actual constellation in the universe, one of the equatorial belt constellations, and the object of study in astronomy, but it does not belong to the twelve constellations in astrology. Therefore, the emoji is generally used to refer specifically to the constellation Ophiuchus in astronomy.
