Newly discovered large asteroid will make flyby on Halloween

A large near-Earth asteroid named 2015 TB145, discovered on October 10 by the University of Hawaiʻi’s Pan-STARRS1 Telescope atop Haleakala, Maui, will pass close to Earth on October 31. The asteroid has a diameter of approximately 400 meters (1,300 feet), and will pass within approximately 480,000 km (300,000 miles) of Earth.  There is no possibility of this object impacting Earth.The asteroid is already being studied by telescopes across the planet, and soon will be targeted by radar observations that will look for details as small as 2 meters (6.5 feet) on its surface. The radar observations will directly measure its size and shape, and determine whether the object has any satellites.
