Planet migration. Computer artwork suggesting the gradual inward migration of a large planet (sphere, centre right) around a distant star (yellow, centre). The path of the planet is shown by the concentric rings around the star. The process may be due to the large gravitational pull between the planet and star and would gradually take place over millions of years. Such an effect may explain the presence of large Jupiter-like planets which orbit close to their stars.
