Doomsday
« on: January 29, 2019, 03:25:59 pm »


Apparently, this thing, named Bennu after the god of chaos, might hit earth.  It's 1600 feet wide.  It has water on the surface.  It might destroy us all.

On average, an asteroid with a diameter of 500 m (1,600 ft; 0.31 mi) can be expected to impact Earth about every 130,000 years or so.[28] A 2010 dynamical study by Andrea Milani and collaborators predicted a series of eight potential Earth impacts by Bennu between 2169 and 2199. The cumulative probability of impact is dependent on physical properties of Bennu that were poorly known at the time, but was found to not exceed 0.071% for all eight encounters.[29] The authors recognized that an accurate assessment of 101955 Bennu's probability of Earth impact would require a detailed shape model and additional observations (either from the ground or from spacecraft visiting the object) to determine the magnitude and direction of the Yarkovsky effect.

The publication of the shape model and of astrometry based on radar observations obtained in 1999, 2005, and 2011,[4] made possible an improved estimate of the Yarkovsky acceleration and a revised assessment of the impact probability. The current (as of 2014) best estimate of the impact probability is a cumulative probability of 0.037% in the interval 2175 to 2196.

Damn! I think I may miss that event. Or maybe I'll get to witness it from some other location.

No help needed, we are doing a good job all by ourselves.

Yeah with our luck we'll just get the world to understand the need to ween ourselves off of fossil fuels and....WHACK.

Why stress about it? Just take a baseball bat and slug it back out of the atmosphere.

If it hits in the summer, you will need to catch it in your lacrosse stick and throw it back.

People have been predicting the end of the world since there were people. Time and time again they have been proven wrong. It is not hard to go back and find endless overwrought predictions of doom from the 90s that are laughable today. Just like the predictions of doom being made today will be laughable in 30 years even as they are replaced by another set of dire predictions because "doom mongers gotta monger".

Well we got hit pretty hard one time which is how we got a moon. Of course we didn't have the technology then to see it coming.

ummm...   Is it still a doomsday prediction if they actually give the odds?

This is basically the plot of the Bruce Willis movie "Armageddon".

An asteroid killed off the dinosaurs, it will happen again some day.
