Procyon VIIIB

Procyon VIIIB was a moon, a terrestrial world located in Sector 006 of the galaxy's Beta Quadrant, in orbit of the binary Procyon star system (also known as Andorian system) in Federation space. It was the second moon of the class J gas giant Andor. 

Details and history
Procyon VIIIB was a barren world, and shared the orbit of Procyon VIII's first moon, the Andorian homeworld Andoria (Procyon VIIIA). Procyon VIIIB was visible when the United Earth starship Enterprise visited Andoria as part of an investigation in 2154. 

The moon was visible to Allied starships from 2409 onwards when q directed them to Andoria to stabilise Omega molecules he had created to celebreate his birthday. 

In 2410, the Alpha Quadrant Alliance defeated an attacking Undine fleet and their Undine planet killer targeting Andoria.
