when did pluto lose its classification as a proper planet?
2006
clyde tombaugh's discovery of pluto in 1930 appeared to validate lowell's hypothesis, and pluto was officially named the ninth planet. in 1978, pluto was conclusively determined to be too small for its gravity to affect the giant planets, resulting in a brief search for a tenth planet. the search was largely abandoned in the early 1990s, when a study of measurements made by the "voyager 2" spacecraft found that the irregularities observed in uranus's orbit were due to a slight overestimation of neptune's mass. after 1992, the discovery of numerous small icy objects with similar or even wider orbits than pluto led to a debate over whether pluto should remain a planet, or whether it and its neighbours should, like the asteroids, be given their own separate classification. although a number of the larger members of this group were initially described as planets, in 2006 the international astronomical union (iau) reclassified pluto and its largest neighbours as dwarf planets, leaving neptune the farthest known planet in the solar system.
