Asteroid 2009 DD45

Asteroid 2009 DD45 zipped past Earth today, March 2nd at 1340 UT, about 72,000 km (0.00048 AU) away. That's only twice the height of a geostationary communications satellite. The 35-meter-wide space rock is similar in size to the Tunguska impactor of 1908, but today there was no danger of a collision--just a close shave.

sorry for my question but how far is 72,000 km (0.00048 AU) ?

[Kowch737]

72,000 km = 44,740 miles

Eugene so based on your video the asteroid has some sort of orbit placement and come back around again? Question, if there is a major solar flare occurrence on the sun during its next flyby, can that flare possibly nudge that asteroid into Earth orbit causing it to enter our atmosphere. Second question can satellites and space stations be effected by these high orbital asteroids, do they have a magnetic core, and can the asteroid become a low orbital asteroid during its next flyby

The 2009 DD45 asteroid circles the sun every 18 months, but its path will not threaten this planet until the next century at the earliest.

does this mean that if it hit the earth, all of us would die?

[Kowch737]

Had asteroid 2009 DD45 hit a populated area, such as a large city, it would have laid it waste. Had asteroid 2009 DD45 hit the ocean it would have caused a tsunami that would have devastated coastlines.

its not cool that we didnt hear about it til it past us. i would of wanted to see it.

[vettafaene]

True. Think it would be world record in how many people went outside at the same time

July 19, 2009 - Jupiter was hit by something big (comet or asteroid). Mainstream media had no idea the event was going to happen. The presumed impact, discovered by Australian amateur astronomer Anthony Wesley July 19 and confirmed by NASA's Infrared Telescope Facility at Mauna Kea, Hawaii, came almost 15 years to the day after multiple fragments of Comet Shoemaker-Levy 9 crashed into Jupiter in 1994. Did world governments think it was going to hit Earth ?

[Matheeous]

was wrong, I did not know that Jupiter was so slow and appeared more or less on July 15

because it appeared Jupiter?

Just download "celestia" (free 3d space immersion viewer), then add the package for the near-earth-objects (NEO) in the addons directory. Assuming you have a good PC (P4 or above), enable the 'orbits' for asteroids and .... in your pants. And space is full of dark objects that we haven't seen yet...especially with the blinding light of the sun.

There is just too much denial about this, come out of your cosy closets and look at the facts.

[dannukesem]

It makes you wonder what else may be out there.

[nickmorganis]

yea and we are all going to die in 2012 blah blah heard it before.

[albertkc2007]

Notice a smaller object on its trajectory avoiding it by maneuvering upwards...around clock timer 0:14 to 0:16. Watch very closely. Friends at work.

i agree, well said you took the words right out of my mind. its pointless to debate with NASA most employees do not want to ask a question because it might infringe upon national security and they might lose their job if they ask the wrong questions. we have a space agency and government that penalizes critical thinking and or common sense.

this fking thing has been coming around undetected many times, ironic it comes around in the month of march. If they are predicting it will hit earth sometime in the future, why arent these people doing anything about it right now?
