Moon
 
a.k.a.
    - The Moon
- Luna? (outside of the series)
Summary
    A planetoid, formerly a
        satellite of the
        planet
        Earth,
        but which broke away after a cataclysm^ known as
        Breakaway.
        It drifts almost completely uncontrolled through space,
        sometimes falling into space warps
        (including a severe one),
        and otherwise appearing to travel vast stretches
        (more in Details).
        On, and dug into it, is a moderately large installation
        named Moonbase Alpha
        (sometimes called just Alpha),
        and at least four nuclear waste disposal areas
        commonly known simply as "Areas."
        At the time of
        Breakaway,
        there were
            311 Earth-born humans
        living on or visiting Moonbase Alpha. | Details
    - The Moon mysteriously survived travel through a
        Black Sun.
        
- The Moon went through a particularly violent Space Warp.
- Other, presumably less-severe, space warps were
        mentioned at least once.  (e.g. in
        "The Metamorph" and
        "The Taybor")
        
- It is not clear if the above all explain the Moon's travel,
        reaching a variety of planets by unspecified means.
        Fans have speculated on supplementary causes as well.
        
- In non-fictional science, some hypothoses or theories suggest
        the Moon originally formed when a Mars-sized body struck the Earth,
        billions of years ago.
        The Moon formed from the molten "splashes" that blasted
        out of both bodies from the collision.
        
- Its course was controlled by the Alphans at least once (in
        "The Seance Spectre")
        by exploding another of the
        nuclear waste dumps.
        This is presumably a finite ability,
        and is very risky.
        
Alternates
    - ATAP (Y1):
        An alternate Moon visibly
        diverged from main one.
        They met up again soon after in episode,
        around Earth (also an alternate?),
        and re-merged.
        
Statements
    - In real life, the discovery of larger deposits of
        frozen water in a permanently shadowed crater near the
        south pole was announced on 2009/11/13.
