Human leg: The human leg is the lower limb extending from the hip to the heel, enabling standing and movement.
Measurements, assumptions & sources +
Luna 2
Luna 2 used an approximately 0.9 m spherical spacecraft bus and had a mass of about 390.2 kg. Antennas and scientific booms extend beyond the calibrated body diameter.
The marked spherical bus diameter is calibrated. Unmeasured illustration details are representative.
Human leg
One complete leg in a defined 70 kg adult model: 1.0 m from hip to heel and 11.68 kg, using published thigh, shank and foot mass fractions. This is a comparison model, not a population average.

Why this measurement?
Why we use 90 cm
For comparison, this page uses spherical bus diameter. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary.
Luna 2 used an approximately 0.9 m spherical spacecraft bus and had a mass of about 390.2 kg. Antennas and scientific booms extend beyond the calibrated body diameter.
The marked horizontal span follows the named feature; transparent margins and unmeasured details do not alter it. How calibrated comparisons work →
