A little perspective
Binary-star planet tidal acceleration vs Parabolic-flight microgravity arc: weight comparison
The equivalent residual force on a 1 kg sample of a parabolic-flight microgravity arc is about 2 times the tidal acceleration across a binary-star planet orbit.
FORCE
Binary-star planet tidal acceleration is the difference in gravitational pull experienced across a planet due to the influence of two stars.
A parabolic-flight microgravity arc is a flight manoeuvre that creates short periods of near-weightlessness for people and experiments inside an aircraft.

Binary-star planet tidal acceleration
Equivalent differential force on a 1 kg body: 0.01 N; defined calculation; range 1 × 10⁻⁵ N–1 N.
A defined 0.01 m/s² differential-acceleration comparison across an Earth-sized planet, expressed as equivalent force on a 1 kg body. It is a model value, not a named exoplanet measurement.
Defined examples — our methodology
The marked equivalent differential force on a 1 kg body is calibrated. Unmeasured illustration details are representative.
Parabolic-flight microgravity arc
Equivalent residual force on a 1 kg sample: 0.02 N; representative; range 0.005 N–0.05 N.
A representative aircraft parabola provides about 22 seconds of reduced gravity. Residual acceleration is expressed here as equivalent force on a defined 1 kg sample.
The marked equivalent residual force on a 1 kg sample is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 0.01 N
We compare the tidal acceleration across a binary-star planet orbit. This is calculated from stated inputs and assumptions, not a direct measurement. The recorded range is 1 × 10⁻⁵ N to 1 N.
A defined 0.01 m/s² differential-acceleration comparison across an Earth-sized planet, expressed as equivalent force on a 1 kg body. It is a model value, not a named exoplanet measurement.
