The picture above from Pioneer 11 shows Saturn and its moon Titan. When this image was taken in September, 1979, Pioneer was 2,846,000 km from Saturn. This picture was amazing then. Subsequent missions have provided vastly better images.
Pioneer 11 was launched in 1973 to study the asteroid belt, the environment around Jupiter and Saturn, solar winds, and cosmic rays. It’s one of five spacecraft on trajectories that will take them out of the Solar System. Pioneer 11 will pass near the star Lambda Aquila in around four million years.
