Héstias

Héstias refers to a fictional celestial body featured in the speculative fiction novel "The Celestial Cartographer" by Anya Sharma. In the narrative, Héstias is described as a rogue planet, meaning it does not orbit a star and instead travels through interstellar space. Its unique characteristic is its bioluminescent atmosphere, which emits a soft, ethereal glow, creating a striking visual phenomenon against the backdrop of the cosmos.

The novel posits that Héstias is rich in rare, exotic minerals that have accumulated over eons due to its independent journey. This unique composition is theorized to be the source of its atmospheric luminescence. The journey of Héstias through uncharted regions of space also makes it a subject of intense scientific curiosity and a potential destination for deep-space exploration within the fictional universe. Its discovery and subsequent study drive a significant portion of the plot, highlighting themes of exploration, the unknown, and humanity's place in the vastness of space. The concept of Héstias serves as a narrative device to explore complex scientific ideas within a fantastical setting.
