Bar length measures mass, not physical size. Both bars start at zero kilograms (kg). Pictures identify the objects only.
A little perspective
3 tonnes is approximately equal to the launch mass of the Rosetta spacecraft.

3 tonnes
Mass: 3 t; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Rosetta spacecraft
Approximate launch mass: 3 t; approximate; range 2.9 t–3.1 t.
ESA’s Rosetta spacecraft spanned approximately 32 m across its two deployed solar-array wings and had a launch mass near 3,000 kg. The Philae lander is included in launch mass, not shown as a separate body.
The marked approximate launch mass is calibrated. Unmeasured illustration details are representative.

- 3 tonnes is approximately equal to the launch mass of the Rosetta spacecraft.
How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 3 t for the launch mass of the Rosetta spacecraft; the recorded range is 2.9 t–3.1 t.
- The launch mass of the Rosetta spacecraft: This is an estimate; check the notes for its rounding and uncertainty.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
Mass is distinct from weight: an object’s mass stays the same as gravity changes.
