b"Recently a relatively dim object, Comet P/2016 BA14 flew past Earth at about 9 times the distance to our Moon from us. It was the third closest comet approach in recorded history. This situation allowed NASA scientists to use the Goldstone Solar System Radar located in California to obtain detailed RADAR images. These revealed the nucleus of P/2016 BA14 to be about 3000 feet in diameter. It slowly spins once very 35 to 40 hours as it travels on its 5.26 year orbital path around the Sun. Observations by the NASA Infrared Telescope Facility on Mauna Kea reveal the nucleus to be as dark as fresh asphalt which means it's surface is about 4 times darker than that of our moon."
