A skull-shaped asteroid last spotted three years ago by astronomers will fly past Earth again next month, just days after Halloween.
Nicknamed 'Great Pumpkin', NASA say asteroid 2015 TB145 is classified as potentially hazardous due to its size. But there's nothing to worry about because the extinct comet is too far away to collide with Earth.
The 'Great Pumpkin' is set to pass Earth, 24 million miles away, on 11th November – that's 1.3 times the distance between our planet and the moon.
NASA first spotted the spooky asteroid – which is around 600 metres in diameter and spherical in shape – by telescope when it came within 300,000 miles of Earth (or a quarter of the distance between the Earth and the moon) on 31st October 2015. Since then, they've kept track of its trajectory from their Infrared Telescope Facility (IRTF) in Hawaii.
Kelly Fast, a program scientist at NASA, said in 2015 that the Space Agency believed 'Great Pumpkin' to be an extinct comet which turned to rock after repeated close encounters with the sun.
"The IRTF (Infrared Telescope Facility) data may indicate that the object might be a dead comet, but...it appears to have donned a skull costume," she said at the time.
Keen amateur astronomers should keep their telescopes poised to see the asteroid next month. It won't come this close to Earth again until 2088.
