In science fiction, a planet killer, planet buster, planet cracker, planet glassing or similar variations on that meaning, is a fictional object or device capable of either destroying an entire planet or otherwise rendering it uninhabitable by a civilized species〔(Planet-Killers ). stardestroyer.net. Retrieved on 2012-08-06.〕 – a variety of a doomsday device. Examples of such devices include the Death Star from the ''Star Wars'' film franchise, the "Doomsday Machine" seen in the original ''Star Trek'' television series or the atomic-powered stone burners from Frank Herbert's ''Dune'' franchise. The term "planet-buster" has also come into use with reference to major natural disasters such as significant asteroid impact events.〔 〕 ==Overview== Planet killers function in a variety of ways depending on the series. Weapons such as the Death Star and the titular ship in ''Lexx'' use a directed energy weapon capable of obliterating a planet in moments. In the game Spore, the planet killer is an antimatter bomb that is inserted in the center of the planet, causing the planet's core to split into countless fragments. Other weapons, such as the Shadow Planet Killer in ''Babylon 5'' and Covenant warships in the ''Halo'' series, render a planet uninhabitable. The Shadow Planet Killer does so by firing missiles which burrow into the planet's core and detonate, causing planet-wide volcanic activity which renders the planet lifeless. Covenant warships use plasma weapons to superheat the surface of the planet; the crust is turned into a glass-like substance rendering it uninhabitable. In ''Star Blazers'', missiles that can destroy a planet (and even a star) with a single hit exist. Some devices can destroy entire star systems. Nova bombs in ''Andromeda'', the Sun Crusher and Centerpoint Station in the Star Wars novels, and Dr. Tolian Soran's trilithium torpedo in ''Star Trek Generations'', are all capable of causing a supernova, obliterating every planet in the solar system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of planet killers」の詳細全文を読む スポンサード リンク
