In a test designed to study its camera's ability to image things close (in angular terms) to the Sun, New Horizons turned back to look at Jupiter again on June 24, 2010, more than three years after its gravity assist flyby. New Horizons was 16.3 astronomical units (more than 2.4 billion kilometers) from Jupiter at the time, meaning that the light from Jupiter took approximately 136 minutes to reach the spacecraft.
