Visible to the naked eye:
* Mercury: Difficult to see due to its proximity to the Sun, but possible under optimal conditions.
* Venus: The brightest planet, often mistaken for a star.
* Mars: Appears reddish and can be easily spotted.
* Jupiter: A bright, yellowish-white "star" that's the largest planet.
* Saturn: Less bright than Jupiter, but still visible as a yellowish star.
Invisible to the naked eye:
* Uranus: Too faint to see without binoculars or a telescope.
* Neptune: Even fainter than Uranus, requiring a telescope to spot.
Important Note: While the above provides a general guideline, visibility can be affected by light pollution, atmospheric conditions, and the planet's position in the sky.
