Comet Lulin, discovered by a Chinese teenager at the Lulin Observatory in Taiwan, is unique for a couple of reasons. First, it is essentially traveling backwards through the solar system. Most of the objects in the night sky, including planets and other comets, travel clockwise around the sun. Not the case with Comet Lulin, which is traveling counterclockwise.The second reason that Comet Lulin will be interesting to see is that it can appear green due to chemicals in the comet.
For the past month, news reports have mentioned people taking photos of the comet as it gets closer and closer to Earth, becoming visible to the naked eye. We like this quote from space.com:
The comet will appear to observers without telescopes as just a fuzzy ball in the sky. It also appears to have formed and lost its tail at least twice due to solar wind gusts. That won’t stop us from checking it out, since we’re located in a rural area that sees nice dark skies at night and no city lights, making for good viewing conditions.
