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.
For 55 Cancri d, this lower limit was approximately 3.835 times the mass of Jupiter. In 2004, astrometric observations using Fine Guidance Sensors on the Hubble Space Telescope indicated that the planet's orbit is tilted by around 53 degrees relative to the sky plane.
