Explanation: Each day on planet Earth can have a serene beginning at sunrise as the sky gently grows bright
over a golden eastern horizon. This sunrise panorama seems to show such a moment on the
winter morning of February 15. In the mist, a calm, mirror-like stretch of the
Miass River flows through the foreground along a frosty landscape near Chelyabinsk, Russia. But the long cloud wafting through the blue sky above is the evolving persistent train of
the Chelyabinsk Meteor. The vapor trail was left by the space rock that exploded over the city only 18 minutes earlier, causing extensive damage and injuring over 1,000 people. A well-documented event, the numerous
webcam and dashcam video captures from the region soon contributed to a
reconstruction of the meteor's trajectory and an initial orbit determination.
Preliminary findings indicate the parent
meteoriod belonged to the Apollo class of
Earth crossing asteroids.
