Voyager 2 passed Neptune in August 1989. Its instruments measured an atmospheric temperature of -220 degrees Celsius (-360 degrees Fahrenheit), with wind speeds as high as 2,100 kilometers per hour, possibly driven from heat radiating deep within the planet. Voyager 2 also made the definitive observations of the planet’s rings and saw storms ...
