Next 10 closest astroids

Anyone fathom a guess..... I sure do not want to be around in 2028... Look at the distance......


Name: Arrival: Miss Distance:

(AU) Astronomical distance Unit: 1.0 AU is about 1.5x10^8 km (roughly the average distance between the Earth and the Sun).
(LD) Lunar Distance: 1.0 LD is about 3.84x10^5 km or 0.00257 AU (the average distance between the Earth and the Moon).

Here is the NASA site for more detailed info.

neo.jpl.nasa.gov...

Has anyone heard of others? I only picked the ones with less than 5 LD. Anyones have any insights on others arriving soon within these distances?

Wow ... and I thought Toutatis was close ... look at the AU for 2003 MK4 ... you'll probaby be able to see that with the unaided eye ... how big is MK4?

Here are the sizes of these three:

1999 AN10 - 0.8 - 1.8 kilometers
2001 WN5 - 0.7 - 1.5 kilometers
2003 MK4 - 190 - 420 meters

If anyone is interested, here is a great link for detailed into on every know near earth object.

neo.jpl.nasa.gov...

Not very big. Remember, at its closest, it will be three times as far away from the Earth as the Moon is... and you would find it hard to make out (even with a telescope) something on the moon that's less than a mile in diameter.

With a good telescope and if you know exactly where to look, at its closest, you might be able to spot it.

the best way to observe an asteroid is when it occults (passes in front of) a star. that's really the only way to see any asteroid. the buggers are too darned small. for more information on this i would recommend going here: The International Occultation Timing Association

2003 MK4 32-Jan-03 18:47 0.6/0.0014

It may not be big, but it definitely isn't three times as far away as the moon is. At 0.6LD, it's a little more than half the distance from the earth to the moon (1.0LD). How big is 420m anyway? Size of a house?

it's just shy of 460 yards. so almost five footballfields in length.

And thats length or square meters? If it's length, that doesn't sound like a very nice outcome if it hit.

As long is you are not the one standing under it...

General Outcomes / Asteroid Impact:

[Small, occurs every 100 years]
<100m water - nothing really, localized fish die, etc
<100m on land = tunguska, but life continues quickly.

[Medium, occurs every 1000 years]
>100m and <1000m strikes land = nuclear 20MT equivalent in terms of damage
>100m and <1000m strikes water = single ocean tsunamis like what wiped out Papa New Guineau

[Super Size that please, once every hundred thousand]
1km or bigger on Land - world-wide nuclear winter for several years and wipe out of a small section of continent where it struck (2000km radius)

1km or bigger on Water - nuclear winter and tsunamis worldwide, wiping out coastal cities (ever see Deep Impact).

generally the size for a non-spherical the size is ust given as the maximum length. i don't know what the area of the asteroids are though.

Ooops! My bad! Nice catch -- I scanned the data and didn't read it as 0.6.


Space.com says it's about the size of a small city.
www.space.com...

just looking through the thread again, and i noticed this one. one lunar distance? anyone know where the moon would be when this one passes? that would be quite interesting to see something hit the moon. (if it could be seen, even)

Good Question, I did not see anything on this. The site only talked about the earth. I am sure all eyes will be watching it when it happens.

Would these comets be the same mentioned in this post?

www.abovetopsecret.com...

Are these comets mentioned anywhere i this post? If you would please tell me which ones. I would love to know. Thanks.

Here is the decoding:

Asteroid No. Time to Impact Data Date Incoming Velocity Asteroid Radius Density Time of Arrival

199 80 days 3-30-04 .887 L/h (222k mph) 993yds(d=1.13mile) 56lb/ft**3 6/18-20 12:34am

005 83 days 3-30-04 .733 L/h (183k mph) 447yds(d=.51mile) 34lb/ft**3 6/24-25 5:51am

003 84 days 3-30-04 .735 L/h (184k mph) 693m(d=.79mile) 72lb/ft**3 6/26-27 10:37am

Asteroid 003 arriving in June has velocities which are varying and therefore draw it´s arrival date into question.

Asteroid 199 has mass around 3.26 x 10**11 lbs which is about 163 million tons.

Needless to say their POA (Plan of Action) is UNKNOWN. The estimated "miss" probability for asteroid 199 is 0.45%

The velocity of the preceeding meteorite shower is being tracked and the maximum shower intensity is being keyed to the last asteroid 003 to " 27/6/04?"

The initial asteroid looks to be impacting around the Falkan Islands off the coast of South America.

Now which of these three are mentioned in this post BEFORE my post? I am sorry if it is really obvious, but I can't seem to find em.
