Asteroid trouble

[Joris]

I looked at the neo.scc file that contains the 2002 MN asteroid in it and figured I could do the same thing by changing the numbers.
I went to NEO at Jpl's website and took an asteroid and copied out the orbital elements.
Here's what I got:

"2000 PH5" "Sol"
{
Class "asteroid"
Mesh "asteroid.cms"
Texture "asteroid.jpg"
Radius 0.035

EllipticalOrbit
{
Period 0.9998
SemiMajorAxis 0.9995879753
Eccentricity 0.229670831
Inclination 1.955565
AscendingNode 283.3121911
ArgOfPericenter 272.6877613
MeanAnomaly 163.4655287
Epoch 2452200.5
}

RotationPeriod 30.0
Albedo 0.1
}

They didn't have the exact radius or rotation period so i left them the same. When I go and try it works and it makes the closest approach at the right time and distance but when I lock on to earth and zoom in and speed up time a bit the earth will shake. Can't really describe it.. you can try it out.
Is is just not possible to copy out numbers.. did I not copy out the right amount of digits or should some program do this instead of me?

Also is it true that 2002 MN is the third closest approach recorded.. the site shows 2002 mn third in the list sortest by minimal possible distance.. pretty close.

So a month later.. and I figured it out.
I was looking at that 2002 nt7 asteroid that someone posted and the earth started shaking again.
I figure this only happens when you are following an object and then lock onto earth and zoom in. It happens to 2002 mn as well as long as it's more than about 0.15 AUs away from earth.

Anyway.. it's not a big discovery but just thought I'd post in case somebody else thinks they screwed up their asteroid.

Here's one that you will be able to see by binoculars or small telescope in two weeks.. only happens a couple times per decade. (I made up rotational period)
