Planet Equilibrium Temperature Calculator

FAQs

How do you calculate the equilibrium temperature of a planet? The equilibrium temperature of a planet can be estimated using the Stefan-Boltzmann law and the planet’s distance from its star, the star’s luminosity, and the planet’s albedo (reflectivity).

What is Earth’s equilibrium temperature? Earth’s equilibrium temperature, considering its actual distance from the Sun and its properties, is approximately 255 Kelvin (-18°C or 0°F). This is significantly colder than its actual average surface temperature due to the greenhouse effect.

Why is Earth not in thermal equilibrium? Earth is not in thermal equilibrium because of the greenhouse effect, which traps heat in the atmosphere and raises the planet’s temperature above its equilibrium temperature.

What increases a planet’s equilibrium temperature? A planet’s equilibrium temperature increases with a higher star luminosity, a smaller distance from the star, and a lower albedo (higher absorption of incoming radiation).
