Separation over time

Measured 1934 → 2015 (81 y)
Separation drift 1.0" → 1.1" (+0.10")
Rate +0.0012" / y
PA drift 90° → 96° (+6°, +0.074°/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.
