ORBITAL ELEMENTS FOR COMET HALE-BOPP (1995 O1)
The following (J2000) osculating orbital elements can be used to
generate ephemeris data using two body programs. However, care must
be taken to select an orbital element set with an epoch close to
the desired ephemeris output times.

ORIGINAL AND FUTURE ORBITAL PERIODS
By integrating the above orbit forward and backward in time until the comet
leaves the planetary system and then referring the osculating orbital elements
to the solar system barycenter, the following orbital periods result:
Original orbital period before entering planetary system = 4200 years
Future orbital period after exiting planetary system = 2380 years
The difference between the inbound and outbound orbital periods is due
primarily to an approach to Jupiter (0.77 AU) in April 1996

R.A. J2000 Dec. = Geocentric astrometric right ascension and declination
referred to the mean equator and equinox of J2000. Light time corrections have been applied
Delta = Geocentric distance of object in AU
Deldot = Geocentric radial velocity of object in km/s
r = Heliocentric distance of object in AU
Theta = Sun-Earth-Object angle in degrees
Beta = Sun-Object-Earth angle in degrees
Moon = Object-Earth-Moon angle in degrees
PsAng = Position angle of extended radius vector in degrees
PsAMV = Position angle of minus velocity vector in degrees
TMag = Total magnitude = -.4 + 5.00*log(Delta) + 7.50*log(r)
