55 Cancri f is fourth in distance from 55 Cancri A of the known planets and orbits at 0.781 AU, inside the habitable zone of the star. PERRYMAN M. & SCHULZE-HARTUNG T. paper, Stellar Parameters and Metallicities of Stars Hosting Jovian and Neptunian Mass Planets: A Possible Dependence of Planetary Mass on Metallicity 0. The planet e's eccentricity is poorly defined; varying values between 0 and 0.4 does not significantly improve the fit, so an eccentricity of 0.2 was assumed. The innermost planet, e, transits 55 Cancri A as viewed from Earth. The true mass is not known due to a limitation with the radial velocity method used to detect the planet. JIANGHUI J., KINOSHITA H., LIN L. & GUANGYU L. [31], The secondary, 55 Cancri B, is a red dwarf star much less massive and luminous than the Sun. MNRAS, 406, 1918 2015 ApJ.

BAINES E., McALISTER H., ten BRUMMELAAR Th., TURNER N., STURMANN J., STURMANN L., GOLDFINGER P., & RIDGWAY S. Astron. & Astrophys., accepted This limits the total mass of fine dust around the star to less than 0.01% of the Earth's mass. [15], The 55 Cancri system was the first known to have four, and later five planets, and may possibly have more. DONNISON J. exoplanetary systems It was transmitted from Eurasia's largest radar – 70-meter (230-foot) Eupatoria Planetary Radar. Measurements of the star suggested that this was close to the star's rotation period, which raised the possibility that the 43-day signal was caused by stellar activity. preprint, Rotation periods of exoplanet host stars ADS, The 55 Cnc system reassessed & VALENTI J. paper, Estimation of the XUV radiation onto close planets and their evaporation Even after accounting for these two planets, a periodicity at 43 days remained, possibly due to a third planet. The nearly 1:3 ratio between 55 Cancri b and c is apparently a near resonance, rather than a genuine mean motion resonance. Given hypothetical planet g of up to 50 Earth masses, stable mean motion resonance regions lie at 3f:2g, 2g:1d, and 3g:2d. BROWN R. 2008 2018 ApJ., 701, 154 HORNER J. Res. KORISKI Sh.

The planet itself is estimated to be at least 44 Earth masses (possibly 57 Earth masses), meaning it is a smaller Neptune-like gas giant. preprint, Stable chaos in the 55Cnc exoplanetary system?

In January 2016, in recognition that his actual name was Lipperhey (with Lippershey an error introduced in the 19th century), the exoplanet name was corrected to Lipperhey by the IAU and that name was submitted to the official sites that keep track of astronomical information.
