Physical properties of a celestial body.

Fields

Section titled “Fields”

mu

Section titled “mu”

mu: f64

Standard gravitational parameter (km^3/s^2)

radius

Section titled “radius”

radius: f64

Mean equatorial radius (km)

Display name

j2

Section titled “j2”

j2: Option<f64>

J2 zonal harmonic coefficient (None for bodies without known oblateness)

j3

Section titled “j3”

j3: Option<f64>

J3 zonal harmonic coefficient (None if unknown)

j4

Section titled “j4”

j4: Option<f64>

J4 zonal harmonic coefficient (None if unknown)

atmosphere_altitude

Section titled “atmosphere_altitude”

atmosphere_altitude: Option<f64>

Effective atmosphere altitude for reentry detection [km]. When a satellite descends below this altitude, it is considered to have entered the atmosphere and the simulation terminates. None for bodies without a significant atmosphere.
