Following the discovery of the planet Neptune in 1846, there was considerable speculation that another planet might exist beyond its orbit. The search began in the mid-19th century and culminated at the start of the 20th with Percival Lowell's quest for Planet X. Lowell proposed the Planet X hypothesis to explain apparent discrepancies in the orbits of the giant planets, particularly Uranus and Neptune, speculating that the gravity of a large unseen ninth planet could have perturbed Uranus enough to account for the irregularities.
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 reclassified Pluto and its largest neighbours as dwarf planets, leaving Neptune the farthest known planet in the Solar System.
Planet X is a term used to describe hypothesized planets, orbiting the Sun beyond Neptune (the 8th planet).

Darlin', we were just starting out
But I can?t deny the someone I saw
Darlin', we were just starting out
Don?t like a sound with it, hope I did right
I won?t pretend
She was less than a friend
Together such a long time ago
Forgot how she made me feel so
Then out of the blue
God gave me you
And this is where my heart is at
And I?ll never look back
Darlin', we were just starting out
But I can?t deny the someone I saw
Darlin', we were just starting out
Don?t like a sound with it, hope I did right
Roll me once again
Are you [Incomprehensible] roll me once again
Soak, soak
Darlin', I?m sure
We?ve got something that's pure
And this is where our love will live
We?ve got so much to give
Roll me once again
Soak into your skin
With all my soul
I?m gonna take hold
Roll me once again
Soak into your skin
With all my soul
I?m gonna take hold
Roll me once again
Soak into your skin
With all my soul
I?m gonna take hold
Darlin', we were just starting out
But I can?t deny the someone I saw
Darlin', we were just starting out
Don?t like a sound with it, hope I did right
We were just starting, starting right here
We were just starting, starting right here
Roll me once again
Are you [Incomprehensible] roll me once again
Soak, soak
Roll me once again
