The Irregular Satellites of the Giant Planets

JOA 2021, Vol. 11, No. 2, Page 3

Author(s): Altair R. Gomes-Júnior

Abstract: The irregular satellites of the giant planets are a class of objects that were probably captured by their host planets. If they were captured, the mechanism of capture and their origins are not known. There is no known mechanism that is able to permanently capture a satellite in the current solar system. Some authors propose different origins, from the Main-Belt of asteroids to the Trans-Neptunian region. The study of these objects may enlighten how the solar system has evolved to allow the capture of satellites. In this work we use stellar occultations to study their properties and identify possible regions of origin for the satellites.
