Ikeya-Murakami: The New Comet on the Cosmic Block

The animation below shows the motion of Comet Ikeya-Murakami on Nov. 13, 2010, captured with a New Mexico-based telescope operated remotely by NASA’s Marshall Space Flight Center. The images were taken near dawn and show the comet’s movement over a period of 45 minutes.  Each exposure was three minutes in length, and the faint angled streak around 0:10 in the animation is a satellite trail. At the time of these images, the comet was some 229 million miles away from Earth.

Comet Ikeya-Murakami was discovered very recently on Nov. 3, 2010, by Japanese amateur astronomers Kaoru Ikeya and Shigeki Murakami. Their discovery is unusual because they both used manual observations through optical telescopes to identify the comet. Such observations are rare in recent times when astronomers use cutting-edge digital imaging to study the skies.

Ikeya-Murakami is classified as a long-period comet, or those comets having eccentric orbits ranging from 200 years millions of years to make one circuit around the sun.

  1. I’m living in south China,last night when I was looking for meteor shower,I found a “star” in the zenith of the sky(almost 5:30 a.m.), shinning like Sirius,just last 5seconds,then disappear,what would it be?

  2. On the far left side of the screen, I see a faint light that looks like it’s just barely moving. Do you think this could be another comet?
