The third stage of Pioneer 11 is thought to be in solar orbit because its encounter with Jupiter would not have resulted in escape from the Solar System. [24] [better source needed] Pioneer 11 gained the required velocity to escape the Solar System in its subsequent encounter with Saturn. [dubious – discuss]

Former planets of the Solar System Former planet Discovery Removal Current status Notes The Morning Star [NB 1]: Antiquity: Antiquity: Aspects of Venus "Phosphorus", the Morning Star of Greek antiquity (Eosphorus, the Dawn-Bringer; called "Lucifer" by the Romans), and "Hesperus", the Evening Star (called "Vesper" by the Romans), were later identified as a single planet, Venus (Aphrodite).
Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
On July 18, 2023, Voyager 2 overtook Pioneer 10 as the second most distant human-made object from the Sun. [71] Pioneer 11, launched a year after Pioneer 10, took similar data as Pioneer out to 44.7 AU in 1995 when that mission was concluded. [69] Pioneer 11 had a similar instrument suite as 10 but also had a flux-gate magnetometer. [70]
A unique cooling system designed by the Applied Physics Laboratory pumps water through the craft’s solar arrays to keep them at a steady temperature of 320 F (160 C), even during close ...
