What is a good method to approximate the distance between me and an object far away?

If you were very far away, you’d just want to measure the angle subtended by the object from you. This will be equal to the angle that you subtend from the object. So you’d just want to measure the angle and take the cosine of the result.

That would be insufficient as no reference to distance has been made.
