The discovery of an atmosphere on a tiny Kuiper belt world, 2002 XV93, challenges our understanding of planetary science. This finding, made possible by precise observations during a 2024 stellar occultation, reveals that 2002 XV93, previously thought to be an airless world, possesses a thin atmosphere. The atmosphere's composition, likely methane or nitrogen gases, extends for approximately 40 kilometers in altitude above the solid surface. This discovery raises intriguing questions about the origin and replenishment of atmospheres in the Kuiper belt. The study highlights the importance of direct observation and experimentation in science, as it contradicts previous assumptions and opens new avenues for research, emphasizing the need to look at the Universe itself to uncover its mysteries.
