Planets beyond Neptune

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.

    The X

    by: Kaskade

    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
