Albedo is a comparison between how much light strikes an object â and how much is reflected. Venus has the highest albedo of any major planet in our solar system. Its albedo is close to .7, meaning it reflects about 70 percent of the sunlight striking it. When the moon is close to full in Earthâs sky, it can look a lot brighter than Venus, but the moon reflects only about 10 percent of the light that hits it.
