Question

Quizplus · Accepted Answer

Jupiter is best observed when it is at opposition, which is when it is closest to Earth. This is because it is at its brightest and can be seen for a longer period of the night. At conjunction, Jupiter is too close to the Sun to be easily observed, and at maximum elongation, it may be too low on the horizon for a clear view. While observing Jupiter high above the southern horizon can still provide a good view, opposition is the optimal time.
