M-1

According to one account, the Daleks were native to a planet orbiting the star Deneb, known to 31st century humanity as "M-1". (COMIC: Daleks, invasión a la Tierra año 2150) Many other accounts gave the Daleks' home planet's name as Skaro. (TV: The Daleks, Dr. Who and the Daleks, etc.)

History
According to one account, Doctor Who was driven to travel back to the 2150 Dalek invasion of Earth because he had seen records on the Earth of the year 3000 of an alien invasion at that time. These records described the invaders as originating from the planet M-1. (COMIC: Daleks, invasión a la Tierra año 2150)

Behind the scenes
As Daleks' Invasion Earth 2150 A.D. was released in Argentina long before Dr. Who and the Daleks (or any other version of the original The Daleks narrative), the comic adaption Daleks, invasión a la Tierra año 2150 was written for an audience unfamiliar with the otherwise-established Dalek homeworld of Skaro. is a real star in the Milky Way. It is unclear whether one should understand "M-1" to be human astronomers' name for Skaro (identifying one of Skaro's "two suns" as Deneb), or a differing, perhaps diegetically mistaken account of the Daleks' origin.
