Separation over time

Measured 1892 → 2015 (123 y)
Separation drift 106.1" → 106.0" (-0.10")
Rate -0.0008" / y
PA drift 84° → 85° (+1°, +0.008°/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.
