For the light-up version of the yo-yo from the late 1970s, see Duncan Satellite (light-up)
The Satellite yo-yo was "launched" by Duncan in the late 1950's, capitalizing on the frenzy and amazement created by the launch of the first artificial satellites into orbit, such as the former Soviet Union's Sputnik 1 and the United States' Explorer 3. With a very unusual bulge-faced profile similar to a Russell yo-yo, this was one of the most popular Duncan models of that period.
Variations on the models did exist, some with flat sides on the bulges, others with completely rounded bulges. At one point in time, there was going to be a version of the Satellite that had featured pointed, conical hubs, but this design never went beyond the prototype stage.
