Close approach of Asteroid 2010 AL30 in 13/jan

[APODman]

A new recently discovered asteroid ( 2010 AL30 ) will cross the skies on this January 13. In the maximum approach it had reached the distance of just 129.000 km to Earth !

Attached are the simulation of the approach of the asteroid.

Isn't it AF30?

Edit: No... cause that isn't even near us now...

Here's a simulation of this encounter, starting a few days before.

1 - Drop this file into the folder:
(My) Documents\Universe Sandbox\Systems
2 - Launch Universe Sandbox (if it's not already running)
3 - Click the Open link (or press F2)
4 - Press the 'My Systems' link
5 - Select the file "Asteroid 2010 AL30 passes near Earth in 2010-01"

Where's the asteroid going to be nearest to the Earth?

EDIT: Nevermind, it's at Southeast Asia/Pacific.

Don't use Universe Sandbox to determine this, the initial rotation of bodies is random and the direction of the axis is probably pointed in the wrong direction. These factors aren't yet calculated or considered.

[Naru523]

Actually, I just clicked the second link (animation) and it was nearest to... you already know.

Wow. I'm sorry. I saw your post and was like... That'd be cool to simulation so I ran off and made a simulation. Sorry for stepping on your toes. I totally missed that you had provided an xml file already.

No problem Dan,

I made my simulation very quickly and I didn't worry about details (the focus on Earth, for example) that optimized the visualization of the event in your simulation.  

Supplementing the topic: a friend found a image of the passage of the object in the skies, captured by astronomers of University of Narino, Colombia:




note: The object reached the maximum visual magnitude of 14,5. Only professional astronomers or very well equiped amateur astronomers could see the passage of the asteroid.

Darn...I missed it

[atomic7732]

14.5 

6-inch scope can only see to 12.

Apodman ,
Do you have any idea what's the funny object is which seems to oscillate or zig-zag at the right of the picture, somewhere at half height ?

[atomic7732]

I looked at the right, I think you mean left.

[Naru523]

Probably a planet?

[atomic7732]

Planets don't move that much in one night, even mercury, which doesn't loop like mars. It cant be Mars because it seems to... idk...

[Bla]

It's probably an artificial satellite, we've launched thousands of satellites while we're only using a few houndred of them...

[Naru523]

Still funny though

A friend ( Fabio Plocos, a great astrophotographer ) explain:

"they are originating from of the chip of the camera and they are not in the space. Those defective pyxels are one of the great problems in the astrophotography of long exposition (for this "dark frames", that exists cooling for CCD, etc...). You see as they are, it follows two filmings of own authorship:

Keyhole nebula:

If they notice there is a problem in guide, the stars move crazily, but some points are fixed... those are the artificial artefacts ! The one that the guys from Colombia did was to catch picture for picture, they aligned the stars so that they were stopped and they set up the animated sequence... they only forgot to remove the workmanships. When they aligned the stars, the artefacts were untidy, causing that illusion that they move accordingly if of the the sequence.

Thanks very much for the explanation Apodman ! This makes sense .
Seems the astrophotographers may have a mot of Photoshop to do if they have bad pixels
