Skaro system
The Skaro system (PROSE: War of the Daleks) was the star system containing the homeworld of the Daleks, Skaro, which was the twelfth planet in the system, (TV: The Daleks) along with Alvega, the closest planet to Skaro. (COMIC: The Amaryll Challenge) One account stated there were two outer planets beyond Skaro, and that system had one sun (PROSE: War of the Daleks) while another account indicated there were two suns. (PROSE: The Stranger)
The entire system was vaporised in the destruction of Skaro, (TV: Remembrance of the Daleks) although the Dalek Prime claimed this was not true and Antalin was actually destroyed. (PROSE: War of the Daleks)
In an alternate timeline, the Doctor had Omega destroy Skaro's system and restore it over and over to prove the meaninglessness of his omnipotence. (PROSE: The Infinity Doctors)
