Review notes: exoplanets
- Recent archive values used: 51 Peg b mass (Cont 2026), Beta Pic b (Sutlieff 2026), TOI-700 d radius (Pass 2026).
- 55 Cnc and HR 8799 spectral types differ between sources; archive values used.
- Image credits include outside contributors: Nick Risinger (51 Peg b), spaceengine.org (LHS 1140 b), SETI Institute (Kepler-186f).
- Kepler-186f, Kepler-452b and TOI-700 d show mass as "Not measured".
- HR 8799 e image is Webb weic2504a.
- 2M1207 b has no orbitAU in its drawing.
Review notes: rockets
- No image: R-7, N1, Proton-M, Long March 5, New Glenn, Electron, H3.
- Ariane 6 image is a CC BY-SA 3.0 IGO media-kit cover with text; Starship image shows only the plume from the ISS; PSLV image is credited to NASA but may be ISRO's.
- Values from Launch Library 2 only: Long March 5 specs, Soyuz-2 height/mass/LEO payload, Delta IV Heavy payloads, R-7 diameter.
- R-7 height of 38 m is a lower bound.
- Counts as of 2026-10-18: Falcon 9 697 flights, 4 failures; Starship 14 flights, 9 successes; Saturn V 12 of 13.
- Proton-M is marked active though it rarely flies.
