Next week the Earth will experience one of the closest encounters ever recorded with two passing comet’s that scientists claim will fly “dangerously close” to the planet. Two twin emerald comets are due to fly past Earth starting on Monday March 21, followed by its sibling the next day. Dailymail.co.uk reports: Nasa astronomers say these two objects will come ‘remarkably close,’ with the latter comet approaching 2.2 million miles from Earth, the third closest flyby in recorded history. The first comet to pass by is known as 252P/LINEAR. Researchers at the Massachusetts Institute of Technology’s Lincoln Near Earth Asteroid Research (LINEAR) discovered the 750-foot-large object on April 7, 2000. They say it will pass Earth at roughly 3.3 million miles away. Another comet was discovered just a few months ago, spotted by researchers at the University of Hawaii’s PanSTARRS telecope on Haleakala, on the island of Maui, on January 22, 2016. While it was initially thought to be an asteroid, the team at the University of Maryland and Lowell Observatory noticed its faint tail, using the Discovery Channel Telescope. This classified the object a comet, which has been called P/2016 BA14. The second comet will fly by Earth at just 2.2 [...]
