Voyager 2 is known for 2 things
Being the only spacecraft to ever visit Neptune and Uranus
Visiting all the outer planets
Voyager 1 was launched on the 5th of September 1977 and Voyager 2 was launched before voyager 1 on the 20th of August 1977.
Uranus had two new rings discovered in 1986 during the Voyager 2 spacecraft flyby. These rings are now known as 1986U2R and 1986U1R.
yes voyager 2 is a space probe
Voyager 2 (also known as Mariner 12)
Voyager 1 arrived in November 1980 and Voyager 2 in August 1981.
Voyager 2 was sent out first to allow it to take full advantage of an unusually convenient alignment of the planets allowing it to visit Uranus and Neptune as wellVoyager 1 was launched after voyager 2, but on a faster trajectory which allowed it to reach Jupiter and Saturn before voyager 2.
Voyager 1 never visited Neptune. Voyager 2 has. Voyager 2 is currently the only scientific instrument to do a fly-by of Neptune.
As of now, Voyager 2 has not found Planet X. The existence of Planet X, also known as Planet Nine, is still a topic of ongoing research and debate among astronomers. It has not been directly observed or confirmed by any spacecraft like Voyager 2.
Voyager 1 and Voyager 2 did not visit the planet Pluto. Voyager 1's trajectory did not take it close to Pluto, and Voyager 2 was redirected after its Uranus encounter to head out of the solar system in a different direction.
