Io, one of Jupiter's largest moons, is a captivating celestial body renowned for its volcanic activity and colorful surface. It is the most volcanically active world in our solar system, with over 400 active volcanoes. The intense tidal forces exerted by Jupiter and its neighboring moons generate immense internal heat, fueling the eruptions that constantly reshape Io's landscape and produce its vibrant sulfur-rich plumes, making it a fascinating destination for planetary exploration. The average surface temperature on Io is -202°F.

Which of these would NOT contribute to the surface temperature of Io?

Answer: A — Size of Io.

Reason: Io’s surface temperature is set mainly by incoming solar radiation (distance from the Sun), how much heat is retained or lost (very thin atmosphere gives almost no greenhouse warming), and internal heating from intense volcanic activity (tidal heating). The moon’s physical size does not directly determine its surface temperature (aside from indirect effects like heat-loss rates), so it is the least direct contributor.
