Separation over time

Measured 1820 → 2017 (197 y)
Separation drift 22.0" → 21.8" (-0.20")
Rate -0.0010" / y
PA drift 328° → 324° (-4°, -0.020°/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.
