It marks the origin - the point where the horizontal and vertical axes cross.
It means 35 miles from the point of origin - NOT there and back.

You're thinking of the origin. The origin is the point (0,0)
The word "origin" means the point (0, 0) on the x-y plane. The meaning of the phrase "origin of an object" is much less certain.
Proximal means nearest the point of attachment or origin.
The medical term for nearest the point of attachment is "proximal."
Proximal means nearer the point of origin.

Origin
The two attachment points are the origin and insertion. The origin is the immovable (or slightly moveable point. The insertion is the movable point. The insertion always moves towards the origin.

Origin and Insertion One of the points of attachment is the ORIGIN (typically the non-moving point of attachment). The other point of attachment is the INSERTION (typically the moving point of attachment). For example - when the brachialis muscle (located on the upper arm) contracts - it shortens the distance between the origin (on the humerus - the upper arm bone and the insertion (on the radius - the forearm bone). The humerus does not move, but the radius does move - it moves closer to the humerus.

Where a muscle attaches to a bone is at the origin and insertion points. The origin is the immovable (or slightly moveable) attachment point and the the insertion is the movable attachment point. During contraction the insertion moves towards the origin. HOW a muscle attaches to a bone is through tendons.
The origin is the "immovable" point of attachment of a muscle to a bone.
