What is the path of the defined CEO?
The CEO moves 66 mas in ICRS right ascension over the next 100 years; its ICRS coordinates at J2100 are RA = 00h 00m 00s.0046, Dec = -00° 33' 25".073 (See the Table).
Table: How far apart the CEO and the equinox are over two centuries (RA in h, min, s; Dec in °, ', ")
