The Sun. It is power, it is life, it is heat, and it is the center of Kerbal-kind's little universe. Kerbal engineers and scientists alike have grown to realize over the centuries, that one day, they can have something like the Sun under them, burning endlessly without dwindling, propelling them above and beyond, and sustaining them in the cold and lonely expanse.

The Sun now possesses 9 biomes. Their purpose is not for opportunities for science gain but to add an element of Astrography to the flight experience. While JNSQ's Sun is correctly proportioned within the JNSQ system, it is 2/3 the size of stock Sun. This consequently shows how unrealistically oversized stock Sun is.
