Kepler space telescope
NASA’s Kepler observatory was about 4.7 m high and had a launch mass of 1,052 kg. The height includes the deployed sunshade but not an imagined launch vehicle.
NASA — Kepler mission in depth
The marked overall observatory height is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares length with overall observatory height. The records below preserve each value’s basis and caveats.

- Comparing
- Length ↔ Overall observatory height
- Relative size
- Kepler space telescope is larger on this measurement by a factor of about 1.03. Kepler space telescope's selected measurement is approximately 2.8% greater than 15 feet's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Kepler space telescope uses a 4.7 m central value within a recorded range of 4.5 m–4.8 m.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
