Non-periodic comet
Comet Lulin (official designation C/2007 N3 (Lulin) , Traditional Chinese :鹿林彗星) is a non-periodic comet . It was discovered by Ye Quanzhi and Lin Chi-Sheng from Lulin Observatory .[ 1] [ 2] [ 7] It peaked in brightness at magnitude between +4.5 and +5,[ 2] [ 8] [ 9] [ 10] becoming visible to the naked eye,[ 11] and arrived at perigee for observers on Earth on February 24, 2009,[ 12] and at 0.411 AU (61,500,000 km ; 38,200,000 mi ) from Earth.[ 12]
