Harriot’s radius is 2.3 times that of earth. So it is about 2 1/3 times bigger than Earth. But it’s density as a gas giant is probably 1.6 g/cm3 similar to Neptune. Earths density is 5.5 g/cm3. That would increase Harriot’s apparent radius and size by 3.5 so that the Harriot would look roughly 8 times bigger than the moon.
From the moon, the Earth appears 4 times as large as the moon from earth.
55 Cancri, Harriot, and Gilead.
Gilead: Moon and new home. The balm of Gilead is a rare medicinal perfume. Phrase came to mean universal cure.
Tidally locked with Harriot. However it also has a libration which means Harriot appears to rock back and forth around the same point in the sky, 4 degrees to each side every 2.5 days. The motion provides a similar effect as do tides on Earth, only the effect is greatest on the side where Harriot is overhead. The eccentricity of the orbit also affects the tides.
55 Cancri B is a red dwarf star binary partner partner and the brightest star in the sky.
Gilead is about 281500 miles from Harriot. (Earth/Moon distance is 238900 miles).
Harriot looks about 9 times as big as the moon does from Earth.
Gilead’s orbital period is roughly 5 Earth days meaning the sun appears to circle the moon once every 5 Earth days. Because Gilead’s eccentric orbit is slightly out of the orbital plain and its axial tilt is similar to Earth’s, it has a winter that varies in intensity. Harriot has an eccentric orbit of about 260 days. The effective growing season is about 100 days on the side away from Harriot and 160 days on the side facing Harriot. Lands half way between those two extremes will have a growing season of about 120 days. At that point, Harriot appears to rise slightly above the horizon and then sink back below the horizon two times in 5 days.
The side of Gilead facing Harriot is never really dark. When that side of Gilead is facing away from the sun, Harriot is reflecting as a full face like 9 full moons. Harriot subtends 4.6 degrees.  If Gilead rotates once in 5 days (120 hours), an eclipse would last 120*4.6/360 = 1.5 hours. When that side faces the sun, Harriot eclipses the sun at least four times a year bringing. The side that never faces Harriot has 2.5 days of light and 2.5 days of darkness.

Lots of solar storms (starspots-regions of strong magnetic storms) make the corona larger and the sun warmer.
Lipperhey (star d) is about 4 times as massive as Jupiter. It is 5.7 AU from 55 Cancri A. Jupiter is 5.2 AU from sun.
Where Harriot is visible, the nights are never dark since light is reflected from such a large surface. That side of the planet IS dark when Harriot eclipses 55 Cancri A. A star-filled sky requires viewing on the side opposite from Harriot visibility.
