sun and the direction to your eye has to be the same angle. The only collection

get white marshmallows, roll them into balls, dip in food colouring and water and leave to dry, then walla! you have your rainbow planets
Light doesn't travel along the rainbow! It travels straight to your eye from every point of the rainbow. The points capable of producing a rainbow for a single individual observer happen to comprise a circular region in space.
The rainbow is actually circular in shape and it appears semi circular in shape to you as the clouds block out the lower part of it resulting in what you see.
ALL rainbows are round. That is, the part of it that you see is part of a circle. If you mean a rainbow that's a complete circle, that's possible if you're up in an airplane looking down, or on top of a mounain looking down into a valley. Just like every other rainbow, the sun must be behind you, and the air in front of you must be full of water droplets.
