Mercury operations - Mercury Planetary Orbiter (MPO)
Osculating elements
The following graphs show some MPO orbital parameters around Mercury.
The gravitational parameter of Mercury used for the calculations is 22031.868551400003 km3/s2 (it's the value used to integrate the JPL planetary and lunar ephemeris DE/LE440).
The following graph shows the eccentricity and the inclination (the reference plane is the mean Mercury equator of J2000).
The following graph shows the orbital period and semi-major axis.
The following graph shows the R.A. of the ascending node and the argument of periapsis (Earth mean equator and equinox of J2000).
