Titan- Satellite of Saturn, Lindsay Pals


This is an image of Titan, one of the seven major moons of the ringed planet, Saturn. This was taken while I was in Astronomy during my second semester, my freshmen year at Calvin. Apparently, I made history. This was the first image taken by our $80,000 telescope that burned it's camera's sensor. My object is very bright and I asked for some images at a ten second exposure time, and that wasn't good for the health of the camera. Hopefully, this isn't charged to my miscellaneous account. I'm already poor.

Titan was discovered by Christiaan Huygens on March 25, 1655. This is a very unique moon because of its gaseous atmosphere consisting of nitrogen and methane. Titan is larger than mercury, and is the second largest moon in the solar system right behind Ganymede, a moon of Jupiter. Titan is probably about half water-ice, and half rocky material. It's surface is fairly smooth, other than some trace impact craters, and there is evidence of volcanic action- similar to that of earth. It is a beautiful and unique moon, and much is to still be discovered about Titan. Titan is the bright star on the upper left side of the bright bulge which is Saturn. the two dots on the left side are probably just stars, and the dot on the right side of Saturn is probably the moon Rhea.

Titan's size is .005018 Astronomical Units (AU) from
