Albedo |verified| Link

When a distant exoplanet passes behind its star, astronomers measure the dip in total light. That dip minus the star's light equals the light reflected off the planet. This is the planet's .

Scientists categorize albedo depending on the light source, surface properties, and viewing geometry: Albedo

Humanity has fundamentally changed the Earth's surface albedo. By replacing grasslands and forests with dark asphalt roads and tar-paper roofs, we have created . Cities become significantly hotter than surrounding rural areas because they absorb and trap solar energy rather than reflecting it. When a distant exoplanet passes behind its star,

Albedo is not a niche physics term. It is the thermostat of our planet. From the microscopic droplets in a summer cloud to the vast, gleaming plains of Greenland’s ice sheet, reflectivity dictates how much of the sun’s fury we absorb or reject.
