Niigata, Japan (KXAN) — People in northern Japan saw a rare fireball streak across the sky early Monday.
A Nippon TV weather camera captured video of the fireball. The fiery, greenish object shot across the sky for 15 seconds before vanishing to the northeast.
One astronomer said the object was likely a brighter-than-typical meteor, which is technically called a fireball. The astronomer speculated that it could have been caused by space debris such as a satellite fragment burning up as it entered the atmosphere.
