Yes, we can identify planets by their distinct motion and steady light. Unlike constellations, which form recognizable patterns of stars, planets move along the ecliptic path and shine steadily, making them distinguishable from the fixed stars in constellations.
Yes, objects called moons or natural satellites move around planets. Each planet in our Solar System, except Mercury and Venus, has at least one moon. These moons orbit their respective planets and vary in size and composition.
