- Comparing
- Mass ↔ Launch mass
- Relative size
- New Horizons spacecraft is larger on this measurement by a factor of about 1.05. New Horizons spacecraft's selected measurement is approximately 5.38% greater than 1,000 pounds's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- New Horizons spacecraft is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
