Our solar system contains a healthy ecosystem of bodies, including a multitude of dwarf planets (like Pluto), a handful of Earth-like solid planets, and a similar number of giant planets. It is natural to wonder about the origin of all these planets. Over the past two decades, the number of planets that we can study have increased from a mere 8 to thousands. The observations of extra-solar debris disks also disclose the presence of dwarf planets around other stars. A new framework for planet formation is called for, to explain the astounding diversity as well as the emergent universality observed in these systems.

我们的太阳系包含一个健康的天体生态系统，包括大量的矮行星(如冥王星)，少数类似地球的固体行星，以及类似数量的巨行星。人们很自然地想知道所有这些行星的起源。在过去的二十年里，我们可以研究的行星的数量从仅仅8颗增加到了数千颗。对太阳外残骸圆盘的观测也揭示了围绕其他恒星的矮行星的存在。需要一个新的行星形成框架，以解释在这些系统中观察到的惊人的多样性和新出现的普遍性。
