Voyager 2 is a space probe used by NASA to explore Jupiter, Saturn, Uranus, and Neptune. It's the only spacecraft that has come near to Uranus and Neptune. Because of this, a majority of pictures we see of these two ice planets came from this spacecraft. It was identical in form to its sister space probe, Voyager 1. The space probe is currently moving away from the solar system, and is heading out into interstellar space.
Voyager 2 was launched on August 20, 1977. It's now in an extended mission. Its encounter with the largest natural satellite of Neptune, Triton sent it on a hyperbolic trajectory out of the solar system, traveling at around 16.62 km/s (37,200 mph; 59,800 km/h) which is much faster than escape velocity.
Both Voyager 1 and Voyager 2 include the Voyager Golden Record, which is a recording of sounds and images of life on Earth. It was designed by a team headed by Carl Sagan to communicate with extraterrestrial life.
Voyager 2 is the second spacecraft, which was able to exit from the solar system and enter into the interstellar space, 6 years after Voyager 1. In 2018, NASA announced that Voyager 2 had reached the heliopause on 5 November of that year. In 2023, Voyager 2 is expected to overtake Pioneer 10 to become the 2nd farthest spacecraft at a distance of around 12.4 billion miles (around 20 billion km) from the Sun.
