Two supernova remnants lie close to the position of supernova 185 AD:

G315.4-2.3, RCW 86, MSH 14-63 . Diameter 42'
G320.4-1.2, RCW 89, MSH 15-52 . Diameter 35'

Positions:

SN 185              14:43.1      -62:28        Cen
G315.4-2.3, RCW 86  14:45:02.30  -62:20:32.00  Cir
G320.4-1.2, RCW 89  15:13:35     -59:00:12     Cen

Estimates of age yield about 2,000 years for RCW 86, about 1,700 years for RCW 89, thus both at about the age of SN 185. Newer investigations, including work with the Chandra X-ray Observatory satellite, seem to favor the first of these SNRs, RCW 86.
