泛星彗星是「泛星巡天計劃」彗星的簡稱，而「泛星巡天計劃」全名是「全景巡天望遠鏡和快速回應系統」(Panoramic Survey Telescope And Rapid Response System 簡寫是 Pan-STARRS)

光科網彗是「國際科學化光學監測網絡 」(International Scientific Optical Network 簡寫是 ISON)彗星的簡稱
http://lfvn.astronomer.ru/00_logos2.png
國際科學化光學監測網絡標誌 ISON 掠日後軌道有變，說明它的質量已改變了。 天文學家認為光科網彗星至今尚未解體，有兩個可能的原因：
（1）彗星緩慢自轉。彗星受熱而出現加速自轉，因而產生強大的離心力不能忽視，高速旋轉足以令彗星解體。如果光科網彗星保持15.7小時緩慢自轉週期，引力仍然可以保持彗核的完整性。
（2）彗星有較大的體積。如果光科網彗星比其它瓦解彗星大得多，重力可以把彗核維持在一起。美國太空總署的研究人員估計，彗核的直大約4.8公里。從現時的彗星活動模型計算，彗核應比原先估計更大，最後的分析彗星直徑可能介乎5至7公里之間，但未有確實觀測數據支持。
