99942 Apophis, previously known by its provisional designation 2004 MN4, is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a probability of up to 2.7% that it would hit Earth on April 13, 2029. Additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in 2029.


Even if this one misses then there are thousands of others out there.

Some are over 10 miles long ( the size of Manhattan) if one of these hits the earth it could sterilise the planet. The last one struck 65 m years ago and wiped out the dinosaurs.

Anyone optimistic.

The madness that ensued in supermarkets post storm Emma with people fighting each other for bread and milk because of some snow showed me that if there is an extinction level event looming it really is best not to tell people about it. Screw all the survivalist nonsense, I'd rather be killed outright.

I will only believe this when then World President Morgan Freeman makes an announcement.

The really dangerous ones would be another `Oumuamua. No warning and moving far too fast to react to.

Moving at 26 km per second, it would make a very large hole.

Not really. It will probably miss.

If we were a rational species, we'd have a couple of hundred Tsar Bombas in parking orbit around the moon, ready to head off in any direction and protect the earth.

As it stands, it would take us 12 months or more to respond to even a certain threat of impact.

A planet 120 trillion miles away is neither use nor ornament.

The nearest star, or sun, to Earth other than the Sun in our solar system is approximately 24 trillion miles from Earth.
If there is a habitable planet in the vicinity of that star, then there might be a chance of survival if Earth begins to die.

The short fact is that humanity will live or die on this planet, because there ain't anywhere else where we can survive.
