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.

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.[4] Voyager 2 is very soon going to be the 2-nd farthest spacecraft from the Earth, when it'll pass one of 5 space probes, which is going to exit from the solar system, which is Pioneer 10. Pioneer 10 was a NASA space probe which was the first spacecraft to exit the outer solar system on June 13, 1983, when it passed the Neptune's orbit. Pioneer 10 is going to be passed by Voyager 2 around April 2023 at around 12.4 billion miles (133.5 AU) from the Sun, while it was passed by Voyager 1 on February 17, 1998 at 6.5 billion miles (70 AU) from the Sun.
