Exploring Pluto's Atmosphere and Surface

The video explores Pluto's atmosphere, which is thin and composed of nitrogen, methane, and possibly carbon dioxide. It discusses how seasonal changes cause the ice to vaporize and refreeze, affecting the atmosphere. The temperature on Pluto is extremely low, around 40° above absolute zero. The solar wind erodes Pluto's atmosphere, potentially creating sublimation scarps and cliffs similar to those on Uranus's moon Miranda. The New Horizons mission may provide insights into these phenomena.

What is the primary component of Pluto's atmosphere?
