In addition to Mars, the five planets that are commonly visible from Earth without telescopes are Mercury, Venus, Jupiter, and Saturn. These planets are often referred to as the "naked-eye planets" and can be seen during specific times of the year depending on their positions in relation to Earth and the Sun.
If you have a specific time frame or conditions in mind (like a particular season or evening), I can provide more detailed information on when these planets might be visible together in the night sky.
