Introduction to the famous aperiodic comet

Comet Lulin is one of the three great comets discovered by Chinese astronomy enthusiasts in recent years. This comet was discovered by Ye, an undergraduate of Guangzhou Sun Yat-sen University, and Lin Qisheng, an observation assistant of Lulin Observatory, Institute of Astronomy, Central University of Taiwan Province, on July, 2007. The International Astronomical Union named it "C/2007N3" comet. This is also one of the most famous discoveries of domestic astronomy enthusiasts.

The Chinese meaning of "C/2007N3" is: "The third comet confirmed in the first half of July 2007 belongs to an aperiodic comet" (that is, there is only one observation opportunity, and the next return will have to wait more than 28 million years). Now it has entered the best observation period. Around February 24 th, it is the closest to the earth, about 60 million kilometers, with a brightness of 4 to 5 stars. If the weather is fine, this comet can be seen with the naked eye. At that time, Comet Lulin will meet Saturn in Leo. It has two tails, and ordinary astronomy lovers can observe Comet Lulin with the help of astronomical telescopes or simple binoculars.
