How to make an object rotate around another object?

Question

Unity

I want the bow to spin around the player character

Answer 1

The answer is within the framework of the author's knowledge:
make a GameObject_1 (GO), in which to put another GO_2. GO_2 shift in local coordinates GO_1. In update rotate through Quaternion GO_1. Position GO_2 - the desired position.
The approach is working, not quite elegant but easy to understand. No math.
