The simplest wormhole geometry is given by the line element , see [2]. The parameter
defines the size of the throat of the wormhole, and
represents the proper length radius.

Details
A detailed discussion about analytic geodesics in the Morris–Thorne wormhole spacetime can be found in [1].
The metric described in [2] was first mentioned in [3]. Hence, it should be called Ellis wormhole instead. See also the apology in [4], Ref. 14.
