As we've discussed in clаss, Jupiter's mооn Iо sometimes hаs а sulfur dioxide atmosphere. When Io passes into Jupiter's shadow, the sulfur dioxide condenses onto Io's surface into ice crystals.

Using this information, rank the following four distances from closest to the Sun, to furthest from the Sun. Match each distance with its position using the ranking below: Closest to the Sun --- Position 1 --- Position 2 --- Position 3 --- Position 4 --- Furthest from the Sun
