Why is the direct detection of exoplanets difficult?

The four moons of Jupiter, for instance, are visible to the unaided eye, but their brightness is millions of times greater than that of the planet that reflects light, making it impossible for us to see them.

Exoplanets are difficult to detect directly for a number of reasons: 1. Brightness Difference: Exoplanets are much fainter than their parent stars, making them difficult to detect against the overwhelming brightness of the stars; 2. Proximity to Stars: Exoplanets orbit close to their parent stars, complicating their detection as they get lost in the glare; 3. Angular Separation: The small angular separation between the exoplanet and its parent star makes it difficult to distinguish between the two; 4. Atmospheric Distortion: Earth's atmosphere distorts and blurs the light from stars, making it difficult to directly image exoplanets; 5. Distance: Exoplanets are located at vast distances from Earth, making it difficult to capture their faint signals amids
