There’s Only a 1 in 7000 Chance It’ll Hit the Earth in September Whenever scientists announce an upcoming close encounter with an asteroid, certain corners of the internet light up like the synaptic rush that accompanies a meth binge, with panicky headlines shouted straight from the brain stem. But never mind that. We’re not that corner of the internet. We’re sober, yo! The fact of the matter is, there aren’t any more near-Earth asteroids than there used to be. We’re just getting good at detecting them. The latest one is called 2006QV89 (We’re going to call it QV for short), and it’s a football field-sized chunk of rock. But don’t let that frighten you, it’s really only 40 meters in diameter (48.5 meters wide x 109 meters long.) Some are feeling panicky, (or they couldn’t care less but want you to panic for clicks). Part of the problem is that the ESA has put it on their risk list, which sounds ominous. All the risk list really means is that the rock has a non-zero chance of striking Earth. It doesn’t mean it’s really big, or that it would threaten civilization if it did collide with us. It just means they’ve taken notice of it and are watching it with one of Earth’s many telescopes capable of keeping an eye on it. No plans to fly into space and make it go boom. According to the ESA, QV has a 1 in 7,299 chance of striking Earth. That’s nowhere near the 1 in 100 threshold that would mean we need to take action. In fact, here’s how insignificant this asteroid is: there are over 850 other asteroids on the risk list, and some of them are near a kilometer in diameter. (The Chicxulub dinosaur-killer was somewhere between 11 km and 81 km in diameter.) more at link...... 1
Calder Posted June 12, 2019 Posted June 12, 2019 So, extremely unlikely and or impossible (at the current time) that it will hit Earth?
ginaboyle275 Posted June 13, 2019 Posted June 13, 2019 Even its kinda impossible to happen, still bothering to know. They even have a new sighting of a mysterious metallic asteroid that could be the heart of a dead planet. I saw the article here. https://www.forbes.com/sites/jamiecartereurope/2019/06/12/nasa-heads-for-psyche-a-giant-mysterious-metallic-asteroid-that-could-be-a-dead-planets-heart/ The universe is getting more creepy.

beecee Posted June 13, 2019 Author Posted June 13, 2019 One of the most potentially dangerous asteroids that we know of is called "4179 Toutatis" with a mean diameter of around 5 kms, so if it did hit, it would be a matter of kiss your Granny goodbye! https://en.wikipedia.org/wiki/4179_Toutatis#Close_approaches_and_collision_risk "The probability of the orbit intersecting Earth is essentially zero for at least the next six centuries.[22] The likelihood of collision in the distant future is considered to be very small" Here are a list of some more NEO's and those that will have approaches closer then the mean distance between Earth/Moon. https://en.wikipedia.org/wiki/List_of_asteroid_close_approaches_to_Earth#Timeline_of_approaches_within_one_lunar_distance
