The comet will pass no closer to us than 84 times the Earth-moon distance.
Applying Isaac Newton's laws of gravity, this means the comet's tidal pull on Earth - at closest approach - will be approximately one-hundred trillionth the force of the moon's tidal pull on Earth. And, we all now know that despite the dreaded Supermoon hype last week, there were no monster storms or earthquakes triggered by our satellite's gravitational tug at closest approach to Earth.
What's more, comets get the worst end of the deal when they venture near larger bodies - just like that mosquito slamming into the supertanker.
Some comets dive-bomb the sun routinely. What happens? They disintegrate into pieces.
The same held true for comet Shoemaker-Levy 9 that was ripped apart by tidal forces when it ventured too close to Jupiter. When the comet pieces plunged into Jupiter in 1994, the planet simply belched a few mushroom clouds from titanic impact explosions.
On May 11, 1983 comet IRAS-Araki-Alcock swept within 3 million miles of Earth –- one of the closest comet approaches in modern times. The visitor looked as big as the full moon and sped across a wide swath of sky in just a few days.
