The distance from the ray's origin to the impact point.

In the case of a ray, the distance represents the magnitude of the vector from the ray's origin to the impact point.

In the case of a swept volume or sphere cast, the distance represents the magnitude of the vector from the origin point to the translated point at which the volume contacts the other collider.

Note that RaycastHit.point represents the point in space where the collision occurs.
