Story summary

A groundbreaking study uncovers the chemical differences between Pluto and Sedna, two intriguing Kuiper Belt objects. While Pluto clings to both methane and ethane, Sedna's smaller size means it can only hold onto methane, as its weaker gravity allows gases to escape. This insight deepens our understanding of how celestial bodies retain volatile substances and shapes the future of space exploration.
