1. In US dictionary transcription, Àdàkọ:USdict. From the Látìnì: Plūto
2. Surface area derived from the radius r: ${\displaystyle 4\pi r^{2}}$.
3. Volume v derived from the radius r: ${\displaystyle 4\pi r^{3}/3}$.
4. Surface gravity derived from the mass m, the gravitational constant G and the radius r: ${\displaystyle Gm/r^{2}}$.
5. Escape velocity derived from the mass m, the gravitational constant G and the radius r: Àdàkọ:Radical.
6. Based on the orientation of Charon's orbit, which is assumed the same as Pluto's spin axis due to the mutual tidal locking.
7. Based on geometry of minimum and maximum distance from Earth and Pluto radius in the factsheet
