In the case of 55 Cancri d, this lower limit was around 3.835 times the mass of Jupiter. In 2004, astrometric measurements with the Fine Guidance Sensors on the Hubble Space Telescope suggest that the planet's orbit is inclined by around 53° with respect to the plane of the sky.
The minimum mass for 55 Cancri d was roughly 3.835 times that of Jupiter. In 2004, astrometric measurements with Fine Guidance Sensors on the Hubble Space Telescope showed that the planet's orbit is inclined by about 53 degrees from the sky plane.
