1. Periapsis is derived from the semimajor axis (a) and eccentricity (e): ${\displaystyle a\cdot (1-e)}$.
2. Apoapsis is derived from the semimajor axis (a) and eccentricity (e): ${\displaystyle a\cdot (1+e)}$.
3. Surface area derived from the radius (r): ${\displaystyle 4\pi r^{2}}$.
4. Volume derived from the radius (r): ${\displaystyle 4\pi r^{3}/3}$.
5. Surface gravity derived from the mass (m), the gravitational constant (G) and the radius (r): ${\displaystyle Gm/r^{2}}$.
6. Escape velocity derived from the mass (m), the gravitational constant (G) and the radius (r): ${\displaystyle \textstyle {\sqrt {2Gm/r}}}$.
