The table shows the parameters of the flybys at the time of the s/c closest approach with the planet.

Planet columns: s/c parameters w.r.t. the planet shown in the "Name" column. R: s/c radius vector (km); h: s/c altitude above the surface of the planet (km); DV: variation of the velocity vector before and after the flyby (km/s).

Sun columns: s/c parameters w.r.t. the Sun. DST: s/c distance from the center of the Sun (millions of kilometers); DV: variation of the s/c heliocentric speed before and after the flyby (km/s).

Lh: s/c heliocentric longitude (degrees).

Select the flyby:

The graph shows the geometry of the selected flyby in the planetocentric mean ecliptic and equinox of J2000 reference frame.

Black dots: s/c position. The popup label shows the UTC time, the s/c radius vector (R, km), the s/c altitude above the surface of the planet (km), the s/c speed w.r.t. the Planet (Vp, km/s) and the heliocentric s/c speed (Vh, km/s).
Purple line: heliocentric velocity vector of the planet at the time of the s/c periapsis.
Yellow line: Sun direction at the time of the s/c periapsis.


The following graph show the radius vector (R), the altitude (h) and the orbital speed (Vp) of the spacecraft w.r.t. the planet. Also shown are the s/c heliocentric speed (Vh) and the osculating orbital inclination to the ecliptic plane of J2000 (I). The x-axis on the top shows the time since the periapsis (in hours).
