Selûne was about 2,000 miles (3,200 km) across and was located some 20,000 miles (32,000 km) away from Toril. To an observer, it appeared about the size of a human fist held at arm's length. It was quite bright on a clear night, able to cast pale shadows.
By the hand of Selûne, goddess of the moon and its namesake, the moon could be a conduit of her powers. In 1357 DR, her avatar Luna used a bright beam of moonlight to transport Conner and the kittenlord to her inn, Selûne's Smile, and later to crack open the roof of a cavern and blind ogres holding the paladin Priam Agrivar.
Due to the size and relative rotation of Selûne and Toril, eclipses were quite frequent and commonplace.
Selûne was full at midnight on Hammer 1, 1372 DR, and subsequently every 30 days, 10 hours, and 30 minutes. Selûne was also full at midnight on the first day of every leap year. Selûne made exactly 48 synodic revolutions every four years, so the phase of Selûne was the same at the same time on the same date every four years. Selûne was generally full around the first day of each month, give or take a day; festival days served to keep the moon's phases consistent across calendar months and years.
