Yes. In Jain cosmology, there are two suns (and two moons) that illuminate Jambudvipa. This is described in traditional Jain texts, which say the two suns and the two moons revolve around Mount Meru, lighting the world as they travel their orbits. The idea helps explain the day-night cycle and the changing light in the vast Jambudvipa, even though it is a cosmological description rather than a modern astronomical one. There is no major, consistent difference between Digambar and Shwetambar accounts on this particular point; both traditions acknowledge the two-sun/two-moon model as part of the Jain view of the world.
