NEO Earth Close Approaches

Close Approach Data!

Quote:

The following table shows close approaches to the Earth by near-Earth objects (NEOs) limited as selected in the “Table Settings” below. Data are not available prior to 1900 A.D nor after 2200 A.D. Data are further limited to encounters with https://cneos.jpl.nasa.gov/ca/neo_ca_info.html

When it comes to a "dangerously close" object that is likely to hit the earth in the near future, no or very little information will be given.

Sure close, but they never seem to hit the earth.

Just my luck.

Random Asteroid 2020!

Why not play the lottery then?

Platapus · 10-21-20, 04:18 PM

And use up all my luck?

No thanks, saving that for the asteroid.

About a "Hypothetical event".

lets not forget about the possibility of a coronal mass ejection large enough to burn off earth's atmosphere, so there's that too.

Trying to remember what a viewer got as an answer to their question.

Question:
How big must a meteor/asteroid be before it can destroy earth - smashed into billions of stones(Like Alderaan in S.W.)

Answer:
The meteor must have a mass of 80 % of earth mass.
A mass lower than this will not destroy earth.
(I could remember wrong though)

I;m not sure it would have to be that big, just big enough to knock Earth out of its orbit.

Platapus · 10-29-20, 01:02 PM

That would depend on what the specific question is

Destroying the earth and destroying life on earth are different. Destroying higher level lifeforms will require a smaller mass than destroying lower lifeforms*

*For the purpose of this post, politicians are not considered lower life forms. Just go with me on this.

Politicians....more akin to pond life mostly

Here Platapus, look if ya can find any luck of random NEO https://en.wikipedia.org/wiki/List_o..._Earth_in_2020

Even if we were to get hit by a rogue planet, if it had a greater gravitational pull or was larger, it would be very likely that we won't collide with the planet but rather we would get "Spaghettified" by its intense gravitational pull. So we would get stretched until we are shaped like an egg and then Earth will give way and it will just explode. The same thing can happen with a black hole. Theoretically, though, we can pass through the black hole unharmed because of the "worm-hole" theory that black holes are a passageway into other places of space. Something with Einstein's theory of relativity.

Though we wouldn't survive for long because we would freeze to death, lol.
