Asteroid 2015 TB145 will be making a close approach to the Earth on Halloween. The asteroid was discovered by the PanSTARRS team, and first noticed by Rob Weryk from London, ON who is a postdoctoral researcher at the University of Hawaii. It is classified as a Potentially Hazardous Asteroid (PHA), and has an inclined orbit – making it a tricky one to find. The asteroid is about 400 m across, and while it will not be visible with the naked eye, there will be telescopes tracking it on Halloween to get a close-up view.
