Here this will help and yes i have N.A.S.A pictures
Elenin entered 03:03:11
------------------------------------
Eliptical orbit 3600 years.
Last Seen 1589 B.C
------------------------------
At the time of the photograph, the comet was 545 million km from the Earth (3.65 a.u.).
239,000 miles from Earth to Moon
Elenin will come within :
???????
-------------------------------------
Earth to The Moon - approx. 238,000 miles (384,000 km) |
The moon is on average 238,857 miles away.
Moon diameter -
"The moon measures about 2160 miles"
--------------------------------------
C/2010 (Elenin) is: 3.5 km = 2.17479 miles in diameter.
So
1 AU=93,000,000 miles
Traveling at 50,400 kilometers per hour.

From Discoverer Of Comet Elenin :
COMET C/2010 X1 (ELENIN)
-------------------------------------
Leonid Elenin (Lyubertsy, Russia) reports his discovery of a comet on
four 240-s unfiltered CCD exposures taken remotely with a 0.45-m f/2.8
astrograph at the ISON-NM observatory near Mayhill, NM, USA, on Dec. 10.435
UT (discovery observation tabulted below).
After posting on the Minor Planet Center’s “NEOCP” webpage,
other cometary astrometrists have noted the object’s cometary appearance.
A. Sergeyev
(Kharkov, Ukraine) and
A. Novichonok
(Kondopoga, Russia)
write that,
Four stacked 300-s CCD images taken with a,
1.5-m f/8 reflector ,,,at the Majdanak Observatory in Uzbekistan on Dec. 11.0
show a teardrop-shaped, very diffuse coma of diameter 6?
(total magnitude 19.1;
magnitude of nuclear condensation 20.7) and a tail of length 10?-12? in p.a.
298 deg.
W. H. Ryan obtained R-band CCD images with the Magdalena Ridge
Observatory’s 2.4-m f/8.9 reflector on Dec. 12.47-12.49 that show the object
to be diffuse with a tail in p.a. about 315 deg. R. S. McMillan, J. V. Scotti,
and M. L. Terenzoni report that five 60-s R-band images taken through thin clouds on Dec. 12.5
with the Steward Observatory 2.3-m f/3 Bok telescope (+90Prime CCD camera) at Kitt Peak in 2? seeing show a coma diameter of about 7? and a tail
extending 10? in p.a. 290 deg.
H. Sato (Ota-ku, Tokyo, Japan)
obtained CCD images remotely with a 0.50-m f/6.8 reflector at the RAS
Observatory near Mayhill on Dec. 12.51 that show an 8? coma and a 45? tail toward p.a. 285 degrees.
2010 UT R.A. (2000) Decl. Mag. Observer Dec. 10.41707 11 58 06.29 – 0 34 20.1 19.5 Elenin
The available astrometry, the following preliminary parabolic orbital elements
by G. V. Williams, and an ephemeris appear on MPEC 2010-X101. It is possible
that this comet is of short period.
T = 2010 Apr. 1.810 TT Peri. = 181.193
Node = 319.659 2000.0
q = 5.15165 AU Incl. = 1.456

"Dear Sir:
Thank you for responding.
I have been reading much of the arrival of c/2010 X1 (Elenin).
To verify that the 3600 year orbit is accurate, " unquote

and yes their is quite the recorded History for this Comet, all quite interesting too say the least.
