1% of the speed of light (0.01c)
Speed: 1% of c (0.01c); definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Mercury
Orbital speed: 170,500 km/h; rounded orbital anchor.
Mean-radius spherical model for Mercury; actual shape is not perfectly spherical.
Rounded representative orbital speed, not instantaneous ephemeris data.
Defined examples — our methodology
The marked orbital speed is calibrated. Unmeasured illustration details are representative.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- Mercury: Rounded representative orbital speed, not instantaneous ephemeris data.
Speed is distance per unit time; it does not specify the total distance travelled.
