Garradd彗星已經可以作為觀測目標

A good target for binoculars and small telescopes, Comet Garradd (C/2009 P1) now shines in planet Earth's evening skies, a steady performer but just below naked-eye visibility. Telescopic images like this composite can find the comet with a lovely green coma, sporting multiple tails, and lingering against a background of faint stars. The field of view spans over 1 degree or about 2 full moons within the southern boundaries of the constellation Hercules. Now around 16 light minutes (2 astronomical units) away, P1 Garradd is an intrinsically large comet, but will never make a very close approach to Earth or the Sun while sweeping through the inner solar system. As a result, the comet will likely stay a sight for telescopic eyes only, moving slowly through the sky and remaining in Hercules during the coming months.

望遠鏡和小型望遠鏡已經可以把Garradd彗星(C/2009 P1)當作觀測目標，現在這顆彗星正在地球的天空下閃爍，它非常穩定,但又低于裸眼能見度。像圖中所展現的這張合成照片里，你會發現這顆彗星像一個可愛的綠色光暈，延展出多條彗尾，對天空中那些微弱的星辰戀戀不舍。視距在南部武仙座范圍內1度或者有2個月亮那樣寬，約16光分(2個天文單位)。P1 Garradd彗星本質上是一個大彗星,但在其掃過太陽系內部時，卻永遠不會接近地球或太陽。該彗星將很有可能繼續只用望遠鏡即可看到,它在天空中慢慢移動并且在未來的幾個月內將一直停留在武仙座。
