Near-Earth Asteroids

Hello,

I've checked out a couple NEA/NEO add-ons in the past, but haven't been satisfied with them for one reason or another. Therefore, I decided to make my own.

The file contains data for 3,840 NEAs, and was current with the MPC Orbit Database as of 06/20/06. Check out the readme.txt for more details.

In what frame did you evaluate your orbital parameters?
What was the frame of the MPC orbit data?

Okay, without any looking into the accuracy of this addon, I like it. Holy crap! It is amazing (and un-nerving) to watch the asteroids move around the system. Nice work.

Oh, nice work!! I share a similar view with buggs_moran, it is a wonderful effort. As I kept some previous NEA/NEO add-ons in disk, I am comparing the difference between the two for their accuracies.

Chalk one up for accuracy.

http://space.com/scienceastronomy/060626_asteroid_close.html

The latest calculations show that 2004 XP14 will pass closest to Earth at 04:25 UT on July 3 (12:25 a.m. EDT or 9:25 p.m. PDT on July 2). The asteroid?€™s distance from Earth at that moment will be 268,624-miles (432,308 km), or just 1.1 times the Moon?€™s average distance from Earth.

Look at the second picture for the view from the asteroid at time referenced in the article. Less than 1000km off. Not too shabby.

I would like to see 2004 MN4 added to the file. That's the 2029 asteroid. I am suprised it was not part of the MPC database.

Buggs,

Any chance you can post a celURL for that viewpoint?

Sorry, I've really got to get better about this...

Thanks Buggs,
Here in return is one of my favorite locations...IMO this is one of the most picturesque places in the solar system...
click on the picture to go there (it's a celURL).
... or maybe there's just something about the colour blue being reminiscent of Earth.
