The Hadean System, Hadeen System, or the Cybertronian System, is a star system centered around the star Hadean. In some universal streams, it is the location of the Transformers' homeworld, Cybertron.

The many planets of the Hadeen System were colonized over 6 billion years ago by the Cybertronian race. As the name implies, the star at the center is Hadeen. The Hadeen System lies within the Milky Way Galaxy. The AllSpark Almanac II

Notes

• The Hadean System is the region of space where Cybertron likely existed in the latter days of the Marvel Comics continuity according to the unofficial story "Alignment". It is unknown why the spelling was changed for The AllSpark Almanac II.
• Outside of the Transformer-specific references, nearly every planetary body in the Hadeen system takes its name from a piece of classical literature. Check the individual articles for more details.
• In an interview, Simon Furman claimed that the IDW version of Cybertron orbited the "star" Shaula. This piece of information has not made it into any media, and, thus far, the system is only referred to as the "Cybertronian System" in "Syndromica (1)".
• Some other continuities place Cybertron in the Alpha Centauri system. In the Marvel Comics continuity, it formed there, but was torn from its orbit and sent hurtling through interstellar space, passing through the Sol System four million years ago.
