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.
much of what is known about Neptune comes from the space probe Voyager II, which passed Neptune in 1989. Neptune was found to have two narrow rings and other fainter ones, as well as six moons. A year on Neptune is equal to almost 1656 Earth years. A Neptunian day is about 18 hours long.
