Abstract

Analysis of the radio tracking data from the Pioneer 10/11 spacecraft at distances between about 20-70 AU from the Sun has consistently indicated the presence of a constant acceleration of 8.6× 10-8 cm/s -2 directed towards the Sun. This has been one of the most interesting and intriguing astrophysical problems in the last decade. Currently, an independent research rises from the planetary long-term orbital evolution study and may be helpful to understand the nature of Pioneer Anomaly. Furthermore, calculation shows that the Pioneer data match with the new discovery's prediction very well.
