Fireball streaks across Australian sky after sunset

An Australian man driving down a road shortly after sunset captured dashcam footage of a fireball streaking across the clear sky. The video, uploaded to YouTube by user ClearSkiesTV, shows the fireball, a meteor catching fire in the earth's atmosphere, streaking downward toward the ground at 5:22 p.m. Friday. "Captured on dash cam, this meteor must have been fairly large to be this easily visible while there was still plenty of light in the sky from the setting sun and the light pollution from a busy area of Sydney," the uploader wrote. "The object that created this fireball is called a 'meteoroid,' a small piece of space rock. Without other photos or videos of the event it is difficult to estimate the size of the rock; it may have been as large as a marble or a tennis ball, and was most likely several hundred kilometers to the north of the dash cam location," the post said.
