P/2016 BA14 (Pan-STARRS) is a near-Earth object and periodic comet of the Jupiter family, that was radar imaged at distance of 2.2 million miles (3.5 million km, or 9 lunar distances) during a flyby of Earth in 2016. This enabled the size of the nucleus to be calculated to be about 3000 feet to 3300 ft (1 km) in diameter. Four noted aspects to BA14 are that it was discovered as an asteroid first, it was much bigger than expected going from perhaps 125 meters to 1000 meters, it was the closest approach by a comet since 1770, and finally, it has a very similar orbit as numbered comet 252P/LINEAR, and may be related to it (e.g. split off of).
