Separation over time

Measured 1821 → 2021 (200 y)
Separation drift 5.1" → 4.5" (-0.60")
Rate -0.0030" / y
PA drift 76° → 77° (+1°, +0.005°/y)

Essentially fixed on human timescales — the same view your grandchildren will see.

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.
