[35] With 8.3 Earth masses, it is a large super-Earth which was originally thought to have an orbital period of 2.8 days, though it was later found that this was an alias of its true period of 0.74 days by observations of e transiting in 2011. paper  arxiv  55 Cancri e is the closest exoplanet to it's star 55 Cancri … & Astrophys., 580, A30 Astron.

The measurements that led to the discovery of this planet also confirmed the existence of 55 Cancri c. In 2005, Jack Wisdom combined three data sets and drew two distinct conclusions: that the 2.8 day planet was an alias and that there was a Neptune-scale planet with a period near 261 days.

It had been thought that with five planets, the system cannot deviate far from coplanar in order to maintain stability.

That means one side of 55 Cancri, referred to as the day side, is always cooking under the intense heat of its star, while the night side remains in the dark and is much cooler.
