In 2001, preliminary astrometric measurements made by the Hipparcos probe suggested the orbit of 47 UMa b is inclined at an angle of 63.1 ° to the plane of the sky, implying the planet's true mass is around 2.9 times that of Jupiter.
If these measurements are confirmed, this implies the planet's true mass is around 2.9 times that of Jupiter. In 2001, preliminary astrometric measurements made by the Hipparcos probe suggest the orbit of 47 Ursae Majoris b is inclined at an angle of 63.1 ° to the plane of the sky.
