Separation over time

Measured 1825 → 2019 (194 y)
Separation drift 2.8" → 3.7" (+0.90")
Rate +0.0046" / y
PA drift 52° → 100° (+48°, +0.247°/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.
