A huge asteroid the size of the football stadium has a close encounter with Earth today (Oct. 31) and you can watch the space rock safely fly by online this Halloween. NASA scientists have dubbed asteroid a cosmic “Great Pumpkin” to celebrate the spooky holiday flyby.

The newfound asteroid 2015 TB145 will buzz Earth 1:01 p.m. EDT (1701 GMT), passing by at a safe range of about 300,000 miles (480,000 kilometers), just beyond the orbit of the moon. The asteroid poses no threat of hitting Earth, but it does give astronomers a tantalizing chance to ping the space rock with radar to learn more about what it’s like.

Today at 1 p.m. EDT (1700 GMT), the online Slooh Community Observatory will host a free live webcast of asteroid 2015 TB145 to discuss the asteroid’s flyby, the “dangers of near-Earth asteroids, the potential fallout of an asteroid this size impacting the Earth or moon and try to understand why it took so long to discover,” according to a Slooh statement.
