Object data of UGC10043 |
|||
| Object type: | galaxy (Sbc) | ||
| Size: | 2.7' x 0.4' | ||
| Magnitude: | 14.8 mag | ||
| Constellation: | Ser | ||
| Distance: | 100 Mio Ly | ||
| Notes: | UGC 10043 is a faint edge-on galaxy with a very thin disk component for a galaxy of this Hubble type. Its outer disk is warped like a slight integral sign, as can be seen clearly in the inverted image. Two possible companions of UGC 10043 are identified in the object identification image: PGC 56100 and a dwarf galaxy named "[MD 2004] Dwarf", which was discovered in 2004 by Matthews + de Grijs. This dwarf galaxy is very faint (brightness = 22mag; surface brightness = 26.1 mag per arcsec2). | ||
