And coming reasonably close (in space terms) to Earth. Interesting to note that we are planning a deflection test, for 2024;

Nasa is currently moving forward with a refrigerator-sized spacecraft capable of preventing asteroids from colliding with Earth. A test with a small, nonthreatening asteroid is planned for 2024.

This is the first-ever mission to demonstrate an asteroid deflection technique for planetary defence.



This is a mildly disturbing number;

'As of December 24, there are 17,495 known Near-Earth Objects (NEOs) around our planet; 17,389 are asteroids', a Nasa spokesperson told the Express last week.

'This year, we discovered 1,985 new near Earth asteroids. There were 1888 such objects discovered in 2016 and 1,571 in 2015'.


One has to wonder if, one of these days, one of these things comes barreling into us.

I'm curious as to what the other 106 NEOs are.

Interestingly enough, for those of us who believe Biblical prophecy, this exact event seems to be one of the things leading to the end of the world:

"Then the second angel sounded: And something like a great mountain burning with fire was thrown into the sea...." [Revelation 8:8, NKJV]


Merry New Year!

I wonder what the butterfly effect of nudging this harmless asteroid will be...

Most likely comets whose partial orbit is close to Earth.

Edit - see https://cneos.jpl.nasa.gov/about/basics.html - yes, comets.

And (crikey!) - https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2017%20QP1
TLDR: ~50m diameter, moving at 24km/s relative to Earth, came within 62000km (roughly 1:6 of the distance to the moon). Missed us last August 14th.

This would be a bit of a problem if we were not so insignificant (in galactic terms)..

Remember the good old days when we had zero knowledge of impending astronomical doom? Any dinosaurs here?

Who says the dinosaurs weren't more technologically advanced than we are, just better at hiding it?

Not necessarily better at hiding it, just better at making sure that anyone who found a way into their underworld never returned...
