Correct answer
B. Iapetus
Explanation
Iapetus, one of Saturn’s moons, has a unique surface with a bright and dark hemisphere. This causes its brightness to vary depending on its position relative to Saturn. Iapetus appears brightest when it is west of Saturn, because its brighter trailing hemisphere is facing Earth. When east of Saturn, the darker leading hemisphere faces us, making it dimmer. This distinctive brightness variation is specific to Iapetus and makes it easily identifiable during favorable viewing. So, Iapetus is the moon that appears brightest when west of Saturn.
Correct answer
B. Jupiter
Explanation
Neptune is correct answer however we have to answer between these four options. The length of a year is determined by the time it takes for a planet to complete one orbit around the Sun. Therefore, the length of a year varies depending on the planet’s distance from the Sun and its orbital speed. For this question, the correct answer is B. Venus. Venus has the longest year among the options provided. It takes about 225 Earth days for Venus to complete one orbit around the Sun. In comparison: Mercury (A) has the shortest year, taking about 88 Earth days to orbit the Sun. Mars (C) has a year approximately 687 Earth days long. The Earth (D) takes about 365.25 days to complete one orbit around the Sun, which we define as one year. The planet with the longest year in our solar system apart from the ones listed is Neptune. Neptune, being the eighth and farthest known planet from the Sun, has an orbital period of about 164.8 Earth years. This means it takes approximately 164.8 Earth years for Neptune to complete one orbit around the Sun.
