Thousands of planets have been discovered orbiting other stars in recent decades. These worlds are so distant that they appear as unresolved dots in the best of cases, but we can still learn about them based solely on disc-integrated light. Indeed, what they lack in detailed observations, they make up for in quantity and diversity: exoplanets provide us with leverage to crack hard problems in planetary science including atmospheric circulation, cloud formation, and geochemical cycling.

近几十年来，已经发现了成千上万的行星在绕其他恒星绕行。这些世界是如此遥远，以至于在最好的情况下它们看起来像是未解决的点，但是我们仍然可以仅根据椎间盘融合的光来了解它们。的确，他们缺乏详细的观察结果，弥补了数量和多样性：系外行星为我们提供了杠杆作用，以破解行星科学中的硬性问题，包括大气循环，云形成和地球化学循环。
