Luna 290 cmSpherical bus diameter · approximate
Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The length of 3 feet is about 1.02 times the spherical bus diameter of Luna 2.
Measurements, assumptions & sources +
3 feet
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
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.

Why these numbers?
The visual compares length with spherical bus diameter. The records below preserve each value’s basis and caveats.

- Comparing
- Length ↔ Spherical bus diameter
- Relative size
- 3 feet is larger on this measurement by a factor of about 1.02. 3 feet's selected measurement is approximately 1.6% greater than Luna 2's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Luna 2 is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
