  Name:	47Uma b	47Uma c
  M.sini:	2.54 MJ	0.76 MJ
  Semi-major axis:	2.09 AU	3.73 AU
  Orbital period:	1089 ± 3 d.	2594 ± 90 d

• Remarks:
  
  • 13 Oct. 03: Naef et al (2003) "are unable with [their] data to confirm the presence of the secondary planet".
  • 12 Feb. 03: 47 Uma is one of the 5 targets of the 14 Feb. 03 "Cosmic Call" initiative 22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 2.9 M_J and inclination of 63.1^o
    
  • 400 other stars monitored at Lick, 660 at Keck and 260 at AAT by Butler and Marcy
  • Upper mass limit of 7 M_J given by Hipparcos (Perryman et al. 1996)
