Trivia

 * The choice of Omicron Persei is no coincidence, in the plot in "When Aliens Attack", the signal had to be a thousand light years away from Earth for the Omicronians to be able to watch it in the year 2999. The writers choose specifically this star as it was just in the right distance.
 * Other known planets of the star are "Omicron Persei 7" and "Omicron Persei 9", but there must be other "Omicron Persei" planets ("Omicron Persei 6", etc.).
 * Unfortunately, O Per is a B-Class star and cannot support life.
