Two Jupiter-family comets - 252P/LINEAR and P/2016 BA14 (PANSTARRS) - will safely fly past Earth on March 21 and 22, 2016 at a distance of 5.2 million km (3.3 million miles) and 3.5 million km (2.2 million miles), respectively. The two comets have intriguingly similar orbits and were thus dubbed "twin comets." Comet P/2016 BA14, discovered on January 22, 2016, was initially thought to be an asteroid, but follow-up observations showed a faint tail, revealing that the discovery was, in fact, a comet. 7 The orbit of this newly discovered comet follows an unusually similar orbit to that of comet 252P/LINEAR, which was discovered on April 7, 2000, and the apparent coincidence may be an indication of twin nature in that comet. P/2016 BA14 is roughly half the size of comet 252P/LINEAR and might be a fragment that calved off sometime in the larger comet's past. "Comet P/2016 BA14 is possibly a fragment of 252P/LINEAR. The two could be related because their orbits are so remarkably similar,"
