Asteroid 2012 TC4 Could Come As Close As 2000 Miles From The Surface Of The Earth

a reply to: MissSmartypants Which part of the earth will be closest to the asteroid when it passes, how large and how fast is it whats it made out of? Maybe i will wait to pay my property tax and go to Charleston SC to watch the Solar Eclipse on August 21. There will probably be a million people there. Make sure all ATSers have their glasses and are ready. will ck for a thread...

a reply to: PsychicCroMag

I'm off to Carbondale, Illinois to see it.

Wouldent want that to hit water ... think that would do the most damage .... or a direct hit on a city both would be bad ... but really in the grand scale of things this is a pebble

Anyone hear hopping for a moon impact i dont think that would hurt us but give us some really nice video of a impact tho

They consider no chance of an Earth impact before Oct, 2020, so I guess Donald will still be around until then!

Who are "they"? If "they" are the elitist controlled NASA then I wouldn't put too much stock in what "they" say.

In that case, just keep an eye on them, and where they might be heading for their 'holidays' in Oct 11th 2020.

last time I looked at the listing for the atmosphere (general term I know) I was 31 instead of 45... going through Flight engineer training...

thank you for the correction.

You and I are vibrating on the same frequency on this one I see.

PsychicCroMag, I'm in Charleston- hopefully the weather will be perfect for the eclipse. It would really suck if we're in the middle of a tropical storm! And speaking of Charleston, it seems we have some sort of natural disaster every October, so I wouldn't be surprised if the asteroid decided to visit here....

Tunguska was estimated at 60-190 meters
it flattened 770 square miles of land
so you can jus guesstimate bout 125 meters

so 125 meters = 770 square miles flattened

and more "guesstimation" here but:

62.5 meters = 385 sqare miles flattened
31.25 meters = 192 square miles flattened
15.62 meters = 96 square miles flattened

thats alot of damage

of course it does not account for angle, type of material its made of, density etc etc etc

Ya know, depending on whether it's going to pass in front of or behind the earth as is skitters past, if it's got leaders and/or trailers we might get an impromptu meteor shower.

I meant 2,000 square kilometers.

a reply to: xSEEKxNxSTRIKEx

Like most explosions destruction from celestial bodies mainly come from shock waves initiated at the point of detonation. Energy transference from point of detonation to either atmosphere and/or ground. To maximize atmospheric effect you must calculate mass, explosive yield, altitude and a few other factors.

a reply to: Jiggly

Speed factors in here. Just because it comes close does not mean it is captured by earth's gravity. Its mass and speed and trajectory relative to earth dictate what type of event this becomes if anything at all.

Where you getting your information from?
I don't see anyone calling for this asteroid to be passing by at 2120 miles.

Probably bad math. There's no reason to subtract the moon's radius because even though the measurement uses the distance from earth to the moon, it's only measuring the distance from earth to the asteroid, so you would actually subtract eart's radius and the asteroid's radius. That's a difference if over 1,000 miles.

a reply to: reddantts



I ditto that



PS:

Apogee and perigee refer to the distance from the Earth to the moon.
Apogee is the farthest point from the earth.
Perigee is the closest point to the earth and it is in this stage that the moon appears larger.

Astronomers have formulas for computing the exact distance at any point in time,
but the average distance from Earth is 237,700 miles

at 237,700 miles average... .03 Earth-Moon distance is closer to 2,377 X 3 = 7,131 miles to be corrected by the moon Apogee or
Perigee.... the math is too variable... the fly--by distance must have been a Typo

From the Jet Propulsion Laboratory's website. It's on their near earth objects close approaches page. Sorry I don't know how to add a link from my phone.

Lunar distance is the distance from the CENTER of the earth to the CENTER of the moon...so yes to get the distance that it will be from the surface of the earth one must subtract the radius of the earth and the radius of the moon. MissSmartypants doesn't make mistakes. Apology accepted.

This is some good ole fashioned ATS doom porn right up in here.
So this is why Trump is allowed to reign? In three months it won't
matter any way!

This page on jpl's website lists the distances in astronomical units rather than lunar distances. An astronomical unit is the distance from the center of the sun to the center of the earth. I just find lunar distances easier to relate to.
