# Planets and major natural satellites of the solar system. Though the IAU
# reclassified Pluto as a dwarf planet in 2006, it is still present in this
# file for historical reasons. There's no defined distinction between 'major'
# and 'minor' satellites. For the most part, the moons included in this file
# are the ones known before the era of Solar System exploration by spacecraft.
# The rest of the solarsystem's natural satellites are in minormoons.ssc and
# numberedmoons.ssc.
#
# The orbital and physical data for the planets necessarily come from a
# variety of sources.
#
#
# === Orbits ===
#
# CustomOrbits are used for most of the large bodies in the solar system.
# These are orbital calculations built into Celestia. In most cases,
# EllipticalOrbits are provided as well in order to give the reader of this
# file some rough idea of the shape and size of a body's orbit. If a body has
# a CustomOrbit defined, its EllipticalOrbit is *not* used by Celestia; the
# CustomOrbit will override the EllipticalOrbit.
#
# For the planets, the orbits are calculated using the VSOP87 theory
# (P. Bretagnon and G. Francou, "Planetary theories in rectangular and
# spherical variables. VSOP87 solutions", Astronomy & Astrophysics 202
# (1988) 309315.
#
# The orbits of the Galilean satellites are from J. H. Lieske's "E5" theory
# as given in Jean Meeus's _Astronomical Algorithms_, pp. 301-315
#
# The orbits of the following Saturnian satellites are from Gerard Dourneau
# (1987), "Observations et etude du mouvement des huit premiers satellites
# de Saturne":
# Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion, Iapetus
#
# The orbits of the five largest Uranian satellites are from Laskar and
# Jacobson (1978), "An Analytical Ephemeris of the Uranian Satellites"
# (Miranda, Ariel, Umbriel, Titania, and Oberon)
#
# **** IMPORTANT ****
# For applications where more accuracy is required, the orbits of any solar
# system body may be replaced by a SPICE kernel or a file of postion/velocity
# samples. Detailed documentation on how to do this may be found on the
# Celestia WikiBook:
# http://en.wikibooks.org/wiki/Celestia/Trajectories#CustomOrbit
# It is also possible to use JPL's DE405 or DE406 ephemeris For the positions
# of the planets, Moon, and Pluto. Details are here:
# http://en.wikibooks.org/wiki/Celestia/JPL_Ephemerides
# *******************
#
#
# === Rotational Elements ===
#
# For most bodies, IAU rotational elements are used. These are implemented
# internally by Celestia and selected by using a CustomRotation. The IAU
# rotational elements are given here:
# http://astrogeology.usgs.gov/Projects/WGCCRE/
#
# UniformRotations are also listed for purely informational reasons; they are
# overridden by CustomRotations (when present.)
#
#
# When alternate data sources are used for orbits or rotational elements, the
# source is noted by a comment in the body definition
