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

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

Astronomers have puzzled for years over a strange pattern in the outer solar system. A surprising number of icy bodies far beyond Neptune resemble snowmen, made of two rounded lobes stuck together.
