NGC 3850 (= PGC 36660)
Discovered (Apr 14, 1789) by William Herschel
A 13th-magnitude barred spiral galaxy (type SB(s)c) in Ursa Major (RA 11 45 35.5, Dec +55 53 12)
A member of the NGC 3898 group of galaxies. Based on a recessional velocity of 1155 km/sec, NGC 3850 is about 55 million light years away, in good agreement with redshift-independent distance estimates of 50 to 70 million light years. Given that and its apparent size of 1.9 by 0.8 arcmins, it is about 30 thousand light years across. |

NGC 3888 (= PGC 36789)
Discovered (Apr 14, 1789) by William Herschel
A 12th-magnitude barred spiral galaxy (type SAB(rs)c) in Ursa Major (RA 11 47 34.0, Dec +55 57 58)
Based on a recessional velocity of 2410 km/sec, NGC 3888 is about 110 million light years away, in fair agreement with redshift-independent distance measurements of 120 to 135 million light years. Given that and its apparent size of 1.8 by 1.4 arcmin, it is about 60 thousand light years across. The galaxy is listed as a member of the NGC 3898 group of galaxies, but is apparently considerably farther away than either NGC 3850 or NGC 3898, so even if physically connected, it must lie at the far end of the group. |

Discovered (Apr 14, 1789) by William Herschel
An 11th-magnitude spiral galaxy (type SA(s)ab) in Ursa Major (RA 11 49 15.3, Dec +56 05 05)
The brightest member of the NGC 3898 group of galaxies (two of the other four being NGC 3850 and 3888). Based on a recessional velocity of 1175 km/sec, NGC 3898 is about 55 million light years away, in fair agreement with a redshift-independent distance estimate of 70 million light years. Given that and its apparent size of 4.4 by 2.6 arcmins, it is about 70 thousand light years across. |
