Apparently the comet "P/2016 BA14" turned out to be Enormous,

the miscalculation of it's size happened due to the comet being very dark and only reflecting 3% of the sunlight

on impact, the blast would have been big enough to wipe out Florida...
...plus a little bit more

Was it the one that was 3.5 million km away?

Tuned in to see why "Misses" is in quotes. I'm pretty sure I'da heard about it if it "hit" Earth.

Although, taking out Florida sounds like a great idea. :devil:

Seriously, screw that state.

yes, 9 times further than the moon

the distance to earth wasn't that shocking, rather that it was 1000% bigger than anticipated


https://en.wikipedia.org/wiki/Near-Earth_object

In the United States, NASA has a congressional mandate to catalogue all NEOs that are at least 1 kilometer wide,
as the impact of such an object would be catastrophic.

As of June 2015, there have been 872 NEAs larger than 1 km discovered, of which 153 are potentially hazardous.[9]
It was estimated in 2006 that 20% of the mandated objects have not yet been found.[8]

As a result of NEOWISE in 2011, it is estimated that 93% of the NEAs larger than 1 km have been found
and that only about 70 remain to be discovered.[10]

The inventory is much less complete for smaller objects, which still have potential for large scale damage.

Earth has mean radius ~6371 km, ~12742 km diameter.
Missing it by 3.5 mln km, means ~275 diameters of Earth.

yes, but again,
i wonder how many other unknown objects out in space that are untracked and 1000% larger than anticipated

Keep wondering, you wonīt get any answers..since nobody knows:D

mjeah...

Tunguska 1908
"...energy about 1,000 times greater than that of the atomic bomb dropped on Hiroshima"


Siberia 2013

I think they missed that siberia 2013 meteorite because the astronomers had their attention to another large object to track at almost the same time, and this one was coming from a direction originating from the sun, and it wasnīt easy to notice..considering itīs size or something like that.

That one was estimated to have exploded between 30-50km above ground, and aproximated to be 17m in diameter, not very large...but they could cause serious damage.
What I wonder is this...
will it be the very large meteors or cometīs that will be the real danger? or the mid level sized ones? those smaller ones may be harder to find and track than the larger ones..the larger ones is probably already registrered.

The question as always, should we send nukes or a drill team to do the job? :) or if there is a better method recently being researched that I donīt know about?

17m in diameter
if it had the same color and reflection as BA14 it would have turned out to be 1000% larger...
170m in diameter, enough to wipe out a city.


nukes or a drill team

but personally i'd fire the laser (!)

Given enough lead time, a solar sail would probably be cheapest.

You only have to spot it soon enough, then apply enough force to alter its course slightly. Of course, that may not eliminate a future impact from the same object, but near term, disaster averted.
