Final answer:
The correct order from closest to most distant from Earth is moon, sun, Pluto, and stars. In a human-sized solar system model, the waist would correspond to somewhere between Mars and Jupiter, with the terrestrial planet zone extending to about mid-thigh to waist level. The nearest stars in this model would be located an unimaginable distance away, symbolically on the other side of our planet.
Step-by-step explanation:
The list, correctly arranged in order of closest-to-most-distant from the Earth, is as follows: moon (a), sun (b), Pluto (c), stars (d). When constructing a solar system scale model based on human height, with the sun at the top of the head and Pluto at the feet, the planet that would be at waist level would be somewhere between Mars and Jupiter, given that Mars is the last of the terrestrial planets and Jupiter is the first of the gas giants. The terrestrial planet zone, composed of Mercury, Venus, Earth, and Mars would only reach to somewhere between the mid-thigh and the waist, depending on the individual's height.
The nearest stars, on this human scale model, would need to be placed tens of thousands of kilometers away, effectively on the other side of the Earth or beyond if the city you live in was used to represent the solar system. This illustrates the vast distances between stars compared to the relatively short distances between objects within our solar system.
