We report the detection of the nucleus of Comet 22P/Kopff with the Planetary Camera of the Hubble Space Telescope (HST) and with the Infrared Camera of the Infrared Space Observatory (ISOCAM). The HST observations were performed on 18 July 1996, 16 days after its perihelion passage of 2 ...
My favourite is the 17p stamp which depicts a bewigged Edmond Halley looking much like his Comet. The 22p stamp shows Giotto approaching the ‘dirty snowball’ nucleus of the Comet while the 31p stamp reminds us that some people may be lucky enough to see Halley’s Comet twice in their ...

22P/Kopff will be at perihelion on 2022 March 18 at 1.55 au. Closest approach to Earth won’t be till 2022 September 14 at 1.39 au though it will be a more distant 2.30 au from Sun at that time. This return is relatively poor with the comet brighter to around magnitude 11 at perihel...

Dynamical Simulation for Probing the Dust Environment of Comet 22P/Kopff The Comet Rendezvous/Asteroid Flyby will be the first mission in the Mariner Mark II program. The July 1990 launch will result in a fast flyby of the asteroid Tanete in May 1991 and a rendezvous with comet Kopff in...
Pierre Hardy的Trek Comet運動鞋不太注重實用性,更關注都市時尚。我們喜歡這對上的單色色調,與花卉襯底相得益彰。厚實的鋸齒狀鞋底非常適合舒適和微妙的高度。 û收藏 转发 评论 ñ赞 评论 o p 同时转发到我的微博 按热度 按时间 正在加载,请稍候......
Tail、Comet - Starscream
We detected the nucleus of Comet 22P/Kopff at 4.87 AU from the Sun with the two IRS peak-up cameras of the Spitzer Space Telescope on April 19, 2007. Using the thermal model of [Groussin, O., and 15 colleagues, 2007. Icarus 187, 16–25], we derive a nucleus size of 1.89 ± ...
