Abstract

Thousands of extrasolar planets have been discovered in our galaxy in the last decades, and the number continues to grow. These discoveries raise fundamental questions about formation, composition and structure of planets. In order to better understand interior structure of planets we have to link it to the planet formation history. Planet interior models usually assume 2-3 layer structure, mainly for simplicity. However, new planet formation models suggest that the composition is probably gradually distributed during planet formation. Here I present the current planet formation mechanisms, and the resulting planetary structure. I discuss what (and if) we can learn about the current planetary interior from planet formation, and how it differs from the old conventional models.
