Paul Fellows, who runs one of the more informative space channels on the Youtube, is looking at the 55 Cancri system. He touches B at the end; today we're back to A, which star some want to name "Copernicus". The accepted planets are b, c, e, and f; e is the famous one, and b is almost a transit. Inclination is generally considered near-edge. Last September, Xiao's Chinese team mooted that binary systems trend coplanar.
The planet-candidate d is a Jupiter-Plus. It orbits a little eccentric, but not by much. From 4600 days, the radial-velocity method takes a while to confirm. Xiao seems to think astrometry has nailed it down, to the expected 5.4 AU. NAMD might not apply for binaries.
Around a 62% luminosity star at only 41 ly, I wonder if we might even see it directly - when it's not in front or behind. The companion B is known to be 8.6 Gy old and the same is assumed for A. Therefore, for A's planets. The light it gets from the star is less than Jupiter gets, but it should have retained more ancient heat than Jupiter has. Or we could constrain d out like for 70 Oph.
