The name came from the Telstar communications satellite, which was roughly spherical and dotted with solar panels, somewhat similar in appearance to the football.
It is common to construct soccer balls by stitching together pentagonal and hexagonal pieces, with three pieces meeting at each vertex (see for example the Adidas Telstar).
