This means that 16.5% of the sunlight that hits Eros is reflected back into space. The remaining 83.5% is absorbed by the asteroid.

It's important to note that the albedo of an asteroid can vary depending on several factors, including:

* Composition: The composition of the asteroid's surface (e.g., rocks, metals, dust) can affect its reflectivity.

* Surface roughness: A rougher surface generally reflects more light than a smooth surface.

* Presence of regolith: A layer of dust and debris on the surface can also influence albedo.

The albedo value of 0.165 for Eros is a representative average value based on observations.
