Apophis

A 25 million ton, 820 foot wide asteroid named after the Egyptian god of darkness and destruction is hurtling straight for Earth. Current projections put the asteroid at actually passing within 20,000 miles of the surface, more skimming than hitting us. Nonetheless, that's within the orbit of most satellites. The real kicker though? There's a possibility, albeit small, that if the asteroid passes us at a distance of 18,893 miles, give or take a few, it will then come back and hit us 7 years later.

So set your calendars, people. The first pass is expected on Friday the 13th of April in 2029, and if it hits that narrow window, it'll most likely come back April 13th 2036 and hit the Pacific Ocean, creating a 5 mile wide and 9,000 foot deep crater that will cause roughly 50-80ft tsunamis. The best part is, there will be tsunamis from the initial impact, but then the water will rush back to try and fill the massive crater, but all that water crashing together at the impact point will send more tsunamis out and this will happen again and again for a good long time until the western US is basically obliterated along with Japan, parts of Russia and basically anywhere else touching the Pacific Ocean. It's also very likely that the impact will shift the tectonic plate enough to set off the Ring of Fire and cause massive volcanic eruptions and earthquakes.

So we have volcanoes, tsunamis, and whatever chunks of the asteroid break of and slam elsewhere around the world all happening at once.

Oh, and we currently don't have the technology to stop it.

And no one is putting money into NASA to fuel development of such technology.

But don't worry, there's only a 45,000 to 1 chance of this happening. So far.
