What is the time frame between the 2 pics? Also, is the missing part in the middle the earth and what about the pixelated blue line/beam, is it a
wrap-around seam?
I wote:wait you lost me a bit we are talking of the "25143 Itokawa (1998 SF36)" asteroid right?
According to NASA's "Ephemeris generator" it will miss us for 0.0129105546 AU (Astronomical Units) or for 5 LS (lunar distance)
on date 26th or 27th June 2004.
1 AU = 149,597,871 kilometers
1 LD = 384,401 kilometers
1 LD also equals 0.00256 AU

So the closes distance from earth is 0.0128971142 AU
ITOKAWA will gradually close to earth and, on June 26, 2004, it will be closest to earth with distance of 0.013AU (about 1.95 million km). But, unfortunately, it will be then located at the south hemisphere. It is estimated that the asteroid will become about twelfth magnitude (about 1,500 times brighter compared to the present).
