Target Description
    ==================
      WASP-3 is a star with a detected substellar companion, WASP-3 b, and
      is a target of the Extrasolar Planet Observation and CHaracterization
      (EPOCh) phase of the NASA EPOXI mission.  Other designations for this
      star are GSC 02636-00195 and 2MASS J18343163+3539415.  The star
      has the following astrometric and photometric properties:
 
        Spectral type        : F7V
        Apparent V Magnitude : 10.64
        Distance             : 223 pc
        Mass                 : 1.24 (-0.11/+0.06) solar masses
        Radius               : 1.31 (-0.12/+0.06) solar radii
        RA                   : 18 34 31.625 (FK5, epoch and equinox 2000)
        Dec                  : +35 39 41.55 (FK5, epoch and equinox 2000)
 
      The substellar companion WASP-3 b was discovered in 2007 by the
      Wide Angle Search for Planets (WASP).  The known properties of this
      extrasolar planet are:
 
        Mass               : 1.76 (-0.14/+0.06) Jupiter masses
        Semi major axis    : 0.0317 (+0.001/-0.0006) AU
        Orbital period     : 1.846834 (-/+2e-6) days
        Eccentricity       : 0
        Radius             : 1.31 (-0.12/+0.05) Jupiter radii
        Inclination        : 85.06 (-0.16/+0.15) deg
 
      The astrometric and photometric properties were taken from the
      21 October 2008 update for this planetary system in the Extrasolar
      Planets Encyclopedia.  The encyclopedia is maintained by the Paris
