A magnitude 11.6 globular cluster (type XI) in
Ophiuchus (RA 17 43 42.2, Dec -26 13 21)
Note About PGC Designation: HyperLEDA assigned a PGC designation to this object (even though it isn't a galaxy), but a search of the database for that designation returns no result, hence its being placed in quotes.
Physical Information: Palomar 6 is thought to be about 7900 light-years away, partially hidden by interstellar dust lying being us and it. Its mass is estimated at about 100 thousand Solar masses, and estimates of its apparent size range from about 10 to 13 arcmin, depending on the point at which there is thought to be little difference between the overall stellar distribution and that of the stars in the general field of view. Given its estimated distance and apparent size, the cluster is probably between 23 and 30 light-years in diameter. Orbital calculations based on the motion of its stars indicate that it has an extremely eccentric orbit which carries it from 6 or 7 thousand light-years from the center of the galaxy at apogalaxion to less than 400 light-years distance from the center at perigalaxion, about once every 25 million years. This means that during the 10 to 12 billion years since its formation (its age is very uncertain), it has passed through the central nucleus of our galaxy more than a thousand times, and its current mass is undoubtedly only a small fraction of its original mass.
Note About The Images Below: Because Palomar 6 lies in more or less the same direction as the disk of the Milky Way, only its core is clearly seen in images of the cluster. As noted in the captions for the PanSTARRS images, its outer regions are at least as large as the 7.5 arcmin wide image, and might be slightly wider than even the 12 arcmin wide image. The much-smaller field of view of the HST images only shows a portion of the central core, using a wider-field image that includes most of the original HST image (albeit re-oriented so that it corresponds to the other images), while the close-up HST image only shows the center of the cluster. The cluster lies in a region where only a monochrome image of the cluster is available in the DSS2 image database, so I have shown it as a black-and-white image, instead of as a false-color image (this is actually closer to what would be seen with the human eye than the other images, since our eyes can't properly discern colors for very faint objects). The PanSTARRS and HST images are false-color images, but are reasonably close to what would be seen if the cluster was bright enough to be seen as anything other than a faint fuzzy blur.
