: Based on a recessional velocity of 6695 km/sec (and H0
= 70 km/sec/Mpc), PGC 1266 is about 310 million light years away. Given that and its apparent size of about 0.45 by 0.3 arcmin (from the images below), it is about 40 thousand light years across. Its apparent companion (NGC 76
) has a recessional velocity of 7325 km/sec and should be 20 to 30 million light years further away, so they are probably merely an optical double.
Misidentification as NGC 84
: PGC 1384 is sometimes misidentified as NGC 84 (hence the warning in the title of this entry), as discussed in the entry for NGC 84
, and the following entry for PGC 1384
: Given the above, see the aforesaid entry for PGC 1384
for anything else.
