In addition, due to it's thicker atmosphere (1.4* times Earth), many non Cygnians do not find they want to reside long on the planet. However, this leads to the much whiter-blue skies of Cygnet, and the spectacular red sunsets, especially on the days that all three suns are visible in the same direction, which often have specific viewing locations and times setup for interstellar tourists.<ref group="notes">Think RGB: (201,246,255)</ref> | In addition, due to it's thicker atmosphere (1.4* times Earth), many non Cygnians do not find they want to reside long on the planet.

Cygnet's three stars are visible at different times from Cygnet XIV, and it has a moon of approximately 2.1* Earth's moon's mass visible. Cygnet's primary, a A7V class star, is a harshly brilliant dot viewable at certain times (approximately 1391 times weaker than Earth's sun during the day), however, it's day is dominated by the closely orbiting binary stars (G3V and K2V), both yellow - are a discs smaller than the size of Earth's sun in the sky but nearly as bright individually<ref name="forestofadistantstar" | Cygnet's three stars are visible at different times from Cygnet XIV, and it has a moon of approximately 2.1* Earth's moon's mass visible.

Cygnet XIV's moon, Sehzair, completes a cycle every 24.21 days, and has an orbital period longer than it's local day of 26.14 hours. Due to it's size and orbital distance, Sehzair's full moon phase is larger than both the suns of Cygnet XIV; and also larger than the Earth's moon by 23%.<ref group="notes">Yes, Cygnet XIV has no lunar eclipses.</ref>. The phase is [TODO: Work out apparent phases, relative brightness] | Cygnet XIV's moon, Sehzair, completes a cycle every 24.21 days, and has an orbital period longer than it's local day of 26.14 hours.
