Even if it hit the earth the odds of it landing anywhere near a city are slim. 3/4 of the time it hits the ocean, Siberia, the Canadian north, or the Antarctic.

- StavrosK 7y agoSerendipitously cooling the surface of the earth down by exactly 2.2 C.
- HeWhoLurksLate 7y agoBring it, punk!
- pault 7y agoPerhaps the solution to climate change is dropping a rock the size of a stadium on Canada every few years.
- setr 7y agoMine some ice from an asteroid and drop it into the ocean, with larger blocks every few years as pollution increases :-)
- teamonkey 7y agoMuch of the ice would vaporise on entry. Water vapor is a greenhouse gas.
- quakenul 7y agoYes. But more importantly, that was a Futurama reference: https://www.youtube.com/watch?v=6cjx4gJFME0 https://www.youtube.com/watch?v=6cjx4gJFME0
- imtringued 7y agoIt can either both prevent sunlight from entering or leaving depending on the altitude.

- ChuckMcM 7y agoAlthough an asteroid of that size, depending on its makeup, can have other damaging effects. For example, by area, the pacific ocean covers a lot of the planet. An asteroid hitting the pacific can cause a tsunami that could seriously damage any coastal city in range.
- ls612 7y agoEven a 390 ft nickel-iron asteroid wouldn’t have enough energy to create a meaningful tsunami. We’re talking energy along the lines of Castle Bravo, not the asteroid that killed the dinos.
- hadlock 7y agoAn asteroid of this size would need to land within 1000 ft of shore to have any meaningful wave height, and would only significantly impact maybe a mile of shoreline. You need to move an impressively large volume of water to create a Fukashima-type event.
- vkou 7y agoOne thing to note: the Tunguska meteor was ~50-200m in diameter, and was equivalent to a 3-30 mega-tonne explosion.
- mrb 7y agoYou massively underestimate the destruction caused by a 1km asteroid. Remember some scientists estimate the asteroid that killed dinosaurs was as small as 11km. In other words a 1km one may be 1/10th the diameter needed to cause an extinction-level event. A 1km asteroid will cause massive casualties no matter where it impacts. If it hits the ocean it will cause a tsunami. If it hits a remote land it will eject so much debris in the atmosphere that they will block sunlight around the globe and reduce temperatures by multiple degrees, thus reducing food crop yields and causing worldwide food shortages and famine.
- vmasto 7y agoThis was a 100m asteroid (city killer), not 1km.
- EForEndeavour 7y agoAnd a factor of 10 difference in linear size (radius, diameter, etc.) implies a factor of 1000 difference in mass.
