Computer Ephemeris. Astrometric Pluto ephemeris. Explanations.
Each row of the table contains for date specified at 0h of Time Terrestrial
- astrometric right ascension (hours, mimutes, seconds),
- astrometric right ascension minus astrometric right ascension of previous
date (seconds of time),
- astrometric declination (degrees, minutes, seconds),
- astrometric declination minus astrometric declination of previous date
(seconds of arc),
- horizontal parallax (seconds of arc),
- apparent radius (seconds of arc),
- geocentric distance (astronomical units),
- geocentric distance minus geocentric distance of previous date (this
number it is necessary to divide on 108 to form number in astronomical
- moment of upper culmination at Greenwich.
Astrometric positions is not an apparent ones. Two main differencies
exists: reference system is J2000.0 and Pluto is referred as a star, but
not Solar system body. Apparent places of Pluto you can see at 'Planets.
