Notes

• The Hadeen System takes its name from the Hadean system, the region of space Cybertron likely occupies in 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 the system is only referred to as the "Cybertronian System" in "Syndromica (1)".
