Part 3/9:
Earth: The Blue Planet
Moving outward, Earth sits a little further from Venus, and because it's habitable, it becomes the benchmark for supporting life. It's only slightly larger than Venus, making it an ideal spot for humans to live, with life-sustaining conditions and a perfect balance of distance from the heat of the Sun.
Mars: The Red Frontier
Next in line is Mars, which appears even smaller and is well known as the "Red Planet." Located much farther from the Sun, Mars experiences colder temperatures, and its proximity makes it a primary candidate in humanity's search for extraterrestrial life. The model shows Mars roughly represented by a small dot considerably distant from Earth.
