So the net result is still a red shift, the Pioneers are not coming back. The blue shift is said to be "unmodeled". Chris

So, when observed, when earth is at right angles moving with respect to the movement of pioneer one observes a redshift. But not as much as could be expected from the formulas of a hyperbolic orbit. But observing it at right angles, this opportunity comes twice a year and there's a difference between these two, it is a length of ca. 14 lightminutes= 2 astronimical units in between and this is filled with lots of radiation from the sun. This should show up in the observation of shift, shouldn't it ? Thanks Hero
