How close will the next one be?

My phone has never made a link like that! :lol:
Actually froze my S3 browser.
I hope someone is making a scenario for Orbiter, to show the close pass and how it affects the orbit. (My first try didn't come close.)

My Birthday !!
Surprise!! We all pitched in and got you a big rock!
*If* I did this correctly, here is the scenario with a DeltaGlider on 2012 DA14's path.
That's great, dgatsoulis! Thank you!
I recommend viewing with the Orbit MFD, showing Earth as target so you can clearly see where the close approach is. It's pretty neat to see the inclination change rapidly just after close approach, and the other elements change, though not so drastically. I also had the Sync Orbit MFD, with Earth as target, to see the distance between them, but it cut out shortly before closest approach (Earth's gravity too strong?). Maybe IMFD's Map mode would work for that purpose?
I think I'll add some RCS propellant, so I can keep Earth in view along with the MFDs.

Why does everyone pick on the east coast, why not the west coast for a change ?
No, HORIZONS uses right-handed coordinate system, Orbiter uses left-handed one. Need to swap Y and Z coordinates for correct conversion.I remember Ajaja using JPL's HORIZONS System to get RL data on MSL's trajectory.
