Radio communications were lost with Pioneer 10 on January 23, 2003, because of the loss of electric power for its radio transmitter, with the probe at a distance of 12 billion km (80 AU; 7.5 billion mi) from Earth.
Pioneer 10 – launched in 1972, flew past Jupiter in 1973 and is heading in the direction of Aldebaran (65 light years away) in the constellation of Taurus.Contact was lost in January 2003, and it is estimated to have passed 134 astronomical units (AU; one AU is roughly the average distance between Earth and the Sun: 150 million kilometers (93 million miles)).
Pioneer 10: Pioneer 10: 3 March 1972 [2] Atlas SLV-3C Centaur-D [3] NASA: Flyby Successful [4] Humanity's first object to attain Solar system's escape velocity. First probe to traverse the asteroid belt, to reach Jovanian system, to use a gravity assist and to leave the proximity of Solar systems' planets.
Pioneer 9 (Pioneer D) – launched November 1968 (inactive since 1983) Pioneer E – lost in launcher failure August 1969; Pioneer 6 and Pioneer 9 are in solar orbits with 0.8 AU distance to the Sun. Their orbital periods are therefore slightly shorter than Earth's. Pioneer 7 and Pioneer 8 are in solar orbits with 1.1 AU distance to the Sun.
On February 17, 1998, Voyager 1 reached a distance of 69 AU (6.4 billion mi; 10.3 billion km) from the Sun and overtook Pioneer 10 as the most distant spacecraft from Earth. [ 47 ] [ 48 ] Traveling at about 17 km/s (11 mi/s), it has the fastest heliocentric recession speed of any spacecraft.
The current distance between the Sun and Pioneer 10 is available on heavens-above.com, so Pioneer 10 is 133.767 AU from the Sun. In miles and kilometers, the current distance is available here . In distance to Earth, hoverer, Voyager 2 will overtake Pioneer 10 on September 23, 2023, when using theskylive.com. 178.95.99.242 ( talk ) 07:11, 18 ...
Pioneer 10 and 11 speed and distance from the Sun Heliocentric positions of the five interstellar probes (squares) and other bodies (circles) until 2020, with launch and flyby dates. Markers denote positions on 1 January of each year, with every fifth year labelled.
Pioneer 10 became the first spacecraft to reach the Jupiter system on December 3, 1973. It passed within 357,000 km (222,000 mi) of Io. [32] During Pioneer 10's fly-by of Io, the spacecraft performed a radio occultation experiment by transmitting an S-band signal as Io passed between it and Earth.
