Sunside

Sunside is a term used to describe the side of an object that is facing the Sun. In astronomy, it is commonly used to refer to the side of a planet, moon, or other celestial body that is illuminated by the Sun. The sunside of a planet, for example, is the portion that is directly exposed to sunlight, while the opposite side is in darkness and is referred to as the dark side or night side. The temperature and atmospheric conditions on the sunside can differ significantly from those on the dark side due to the presence or absence of sunlight. On Earth, the sunside is the portion of the planet that is facing the Sun at any given time, and it experiences daylight. The term "sunside" is also used in a broader context to describe any situation or environment that is exposed to or influenced by the Sun.
