Only a few weeks ago, on October 10, the survey telescope Pan-STARRS 1 discovered an asteroid – 2015 TB145 – that was classified as potentially hazardous. Because of its brightness, it is estimated to measure 320 metres across, and further observations have revealed that it will race past Earth and the moon on October 31 at 17:05 UTC. In fact, you'll be able to watch it here.
