2 Comets Will Pass By Earth This Week — The Closest In 250 Years
Two comets with the same orbit will pass by Earth this week and give scientists the chance to study possible twin comets.By Melissa Prax | March 20, 2016
Two comets will pass by Earth this week, and one will come close enough to break a 250-year record.
Comet P/2016 BA14 will still be a safe 2.2 million miles away when it flies by on Tuesday, but it will take the record for the third-closest comet to Earth on record.
And there's another twist that's getting scientists excited. 252P/LINEAR, the bigger comet set to fly past Earth on Monday, might be related to P/2016 BA14 — as in twins.
