The first spacecraft to explore Jupiter was Pioneer 10, which flew past the planet in December 1973, followed by Pioneer 11 twelve months later. Pioneer 10 obtained the first close-up images of Jupiter and its Galilean moons; the spacecraft studied the planet's atmosphere, detected its magnetic field, observed its radiation belts and determined ...
Argo was a 2009 spacecraft mission concept by NASA to the outer planets and beyond. [ 1 ] [ 2 ] [ 3 ] The concept included flybys of Jupiter , Saturn , Neptune , and a Kuiper belt object . [ 1 ] A focus on Neptune and its largest moon Triton would have helped answer some of the questions generated by Voyager 2 's flyby in 1989, [ 1 ] and would ...

NASA's Juno spacecraft recently flew by Jupiter, collecting crucial data -- and the best look we've gotten at the planet in a very long time. This is the closest photo of Jupiter anyone has seen ...
For comparison, Neptune's mass equals 17 Earth masses, Jupiter has 318 Earth masses, and the 13-Jupiter-mass limit used in the IAU's working definition of an exoplanet equals approximately 4000 Earth masses. [62]
Just one day before opposition, Jupiter will be around 367 million miles away from the Earth, the closest the two planets have been in 59 years, according to NASA. The last time that Jupiter was ...
