Cestrell

Cestrell is a fictional celestial body featured in the science fiction novel "Starfall" by Anya Sharma. It is described as a gas giant located in the Kepler-186 system, approximately 500 light-years from Earth. Cestrell is notable for its unusually vibrant auroras, which are said to be visible even from space. The novel suggests that these auroras are caused by a unique interaction between the planet's atmosphere and its parent star, Kepler-186.

The planet's composition is believed to be primarily hydrogen and helium, with trace amounts of other gases that contribute to its distinctive atmospheric coloration. Cestrell possesses a complex ring system, composed of ice and dust particles, which further enhances its visual appeal. Its moons are largely unexplored, though the narrative briefly mentions a few small, rocky satellites. In the context of "Starfall," Cestrell serves as a landmark and a point of scientific interest for the human explorers. Its immense size and energetic phenomena play a role in the narrative's depiction of interstellar travel and discovery. The novel does not provide extensive scientific detail about Cestrell, focusing instead on its aesthetic and narrative significance within the fictional universe.
