Quizplus · Accepted Answer

Planetary systems discovered around other stars exhibit a range of different layouts, some being very similar to our solar system while others being very different. This is because different planetary systems form under different conditions and therefore have unique configurations. While some systems may have planets arranged in a similar manner to our solar system, others may have planets in more elliptical or widely spaced orbits, or even have gas giants closer to their star than Mercury is to our sun.
