Skull-Shaped 'Great Pumpkin' Asteroid Flew by Earth on Halloween 2015

On October 31, 2015, a large asteroid with an eerie resemblance to a human skull made a close approach to Earth, earning it the nickname the 'Great Pumpkin' from NASA. Officially designated 2015 TB145, the asteroid passed at a distance of about 302,000 miles (486,000 kilometers), just outside the moon's orbit. Radar images from the Arecibo Observatory revealed its skull-like features, including eye sockets and a nasal cavity, sparking widespread fascination and media coverage. The asteroid, estimated to be about 2,000 feet (600 meters) in diameter, is likely a dead comet that has shed its volatile materials. Its Halloween flyby provided a rare opportunity for scientists to study a near-Earth object of this size up close, helping refine models of asteroid composition and trajectory. The event underscored the importance of tracking near-Earth objects, as an impact from an asteroid of this size could cause significant regional damage. The 'Great Pumpkin' won't return until 2088, but its spooky visit remains a reminder of the cosmic threats that lurk in our solar system.
