Separation over time

Measured 1831 → 2015 (184 y)
Separation drift 13.5" → 14.6" (+1.10")
Rate +0.0060" / y
PA drift 162° → 159° (-3°, -0.016°/y)

Slow change over generations — observable in lifetime comparisons.

Measured from the WDS observational archive. No orbital solution has been derived — most likely the period is too long to fit an orbit to the available measurement arc.
