      Canopus right ascension (2012): 6h 23m 57.1s
      Canopus right ascension (2012): 23037.1 sec (of angular time)
      Canopus proper motion in RA: +19.99 mas/year


      Canopus declination (2012): −52° 41' 44"
      Canopus declination (2012): −189704 arcsec
      Canopus proper motion in dec: +23.67 mas/year


      Difference in time: −12457 years


      Remember that a second of angular time is 15" multiplied by the cosine of the declination.


      Canopus right ascension (10446 BC): 6h 23m 29.7s
      Canopus declination (10446 BC): −52° 46' 39"
