FIRE RAIN

Fire rain is the local name used by the Edorans to describe the meteor shower that is visible from their planet at the same time each year. The fire rain is caused by Edora's orbit passing harmlessly through an asteroid belt, however, the irregularity of the belt results in an impact event approximately once every 150 years.
