Abstract
Despite the now common position that the Pioneer
anomaly is not a real gravitational effect but an effect due to the
on-board thermal recoil forces – for curiosity’s sake, we here take
the suggestion of Nyambuya (2015) where it has been assumed that
the Pioneer anomaly – can, in-principle, be attributed to a gravitational
effect due to these spacecrafts accreting some material from
a rarefied Interplanetary Medium (IPM) in the domain where the
Pioneer anomaly has manifested [20AU . r . 70AU]. If this
assumption is correct, then, the expected Pioneer acceleration of
these spacecrafts maybe much smaller than the Pioneer acceleration
to cause as noticeable apsidal precession of the outer Solar
planets Uranus, Neptune and Pluto, thus making it difficult to ruleout
a gravitational origin of the Pioneer anomaly.
