The exoplanet TrES-2b is considered the darkest known planet.
TrES-2b: The Darkest Exoplanet
Based on current observations, TrES-2b holds the title of the darkest known exoplanet. This remarkable planet reflects less light than coal or even black acrylic paint. Scientists are still investigating the reasons behind its extreme darkness.
Understanding Darkness on Exoplanets
- Light Absorption: Unlike planets like Earth that reflect a significant amount of sunlight, TrES-2b absorbs nearly all the light that falls on it.
- Atmospheric Composition: The exact composition of TrES-2b's atmosphere, which contributes to its light absorption, remains an area of study for astronomers.
- Comparison to Earth: Earth's albedo, or reflectivity, varies depending on cloud cover and surface features. TrES-2b stands out due to its remarkably low albedo.
