Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7455. Is this perhaps Encke's Comet of 1885? Swift claims that he found the nebula while searching for the comet. There is nothing near his place, and the galaxy usually taken as N7455 does not have a "pS * nr p" as Swift notes. As Howe first noted, the star is 10th magnitude and 6 arcmin northeast of the galaxy. Also, Swift's brief description (eF, cE) might fit a comet quite well.

Still, the RA is off in the same direction as are those for NGC 7452 and NGC 7459 (both of which see), and Howe picked up the galaxy in spite of its faintness.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 15.5 mag galaxy. Their coded description reads R,HISB,DIF EXT TO N.
