Separation over time

Measured 1834 → 2022 (188 y)
Separation drift 76.6" → 75.8" (-0.80")
Rate -0.0043" / y
PA drift 287° → 287° (+0°, +0.000°/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.
