A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Astronomers have found a distant world that challenges planetary formation theory, with a rocky planet where gas giants should be.

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...
