Each track shows distance covered in the same second. The small illustrations identify the movers; their sizes are schematic.
A little perspective
Pluto moves about 1.38 times as fast as Mach 10.
Measurements, assumptions & sources +
Mach 10
Mach depends on sound speed. Here Mach 1 is 343 m/s in dry air at 20 °C.
Pluto
Mean-radius spherical model for Pluto; 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.

Why these numbers?
The visual compares speed with orbital speed. The records below preserve each value’s basis and caveats.

- Comparing
- Speed ↔ Orbital speed
- Relative size
- Pluto is larger on this measurement by a factor of about 1.38. Pluto's selected measurement is approximately 38.2% greater than Mach 10's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Pluto: Rounded representative orbital speed, not instantaneous ephemeris data.
