APOD: 2002 September 11 - Pluto and Charon Eclipse a Triple Star |
| Occasionally, a planet in our Solar System will pass in front of a bright star. Since stars and planets take up so little space on the sky, such events are quite rare. Two months ago, however, Pluto and its large moon Charon passed in front of a comparatively bright triple star system known as P126. |
