C/2010 X1 (a.k.a. “Elenin”) Data and Image

JPL’s data on C/2010 X1, a.k.a “Elenin” can be found here-


In the event you are unable to see it, here are the highlights.

Time of closest approach= Oct 16, 2011 @ 1950 UTC

Apparent Magnitude on 10/16/2011 will be 6.95

Distance on 10/16/2011=0.2338459….. AU

or 34,982,848.7098205169 km

or 21,737,334.40237683669 miles

Speed= 23.909 km/sec

(This next stat I am not sure of what it signifies, but I assume it represents how close to the orbit of Earth it will pass)

MOID(Minimum Orbit Intersection Distance)= .0306272 AU

or 4,581,763.9052273952 km

or 2,846,976.0992537215 miles

….and now for the mind-blowing data…


Equatorial= 6378.1 km (3963.1675 miles)

Meridian= 6378.1 km (3963.1675 miles)

Pole= 6356.8 km (3949.9323 miles)

The diameter of C/2010 X1 stretches from Cape Kennedy in Florida to The Canary Islands!


Diameter of some bodies within the Solar System, smallest to largest…

Pluto= 2,300 km

The Moon= 3,475.6 km

Mercury= 4,878 km

Elenin=6,378.1 km

Mars=6,796 km

Earth= 12,756 km

When she passes at 21 million miles, we shall see… I do not know! The Moon is 250,000 km away. The moon is half the size of C/2010 X1. We will pass through the tail of this comet this year after it passes. We will see if the theory holds that some of our deadly pathogens come from close encounters with comets.

This is a very unique experience. Not too many civilizations have seen a body like this pass within such a short distance. sadly, the ones who did see something like this and were able to document it, don’t seem to have a very positive experience afterwards…. (sigh)

Keep your head up.
