Hot Jupiters Can Co-Exist with Other Planets

The WASP-132 system was know to harbour WASP-132b, here in the foreground, a hot Jupiter planet orbiting around a K-type star in 7.1 days. New data confirms the system has more planets, including an inner super-Earth, here seen transiting in front of the orange host-star. Visible as a pale blue dot near the top right corner is also the giant planet WASP-132d discovered in the outskirts of the system.

Exoplanets come in a variety of forms and one particular type, the Hot Jupiters have recently captured the attention of astronomers. They are usually found orbiting extremely close to their host star, completing an orbit in a few days or even hours. It has been thought that they migrated further out from the star, bullying other planets out of their way. Sometimes hurling them into the star or throwing them out of the system entirely. A new study however, suggests their evolution is not quite so violent since a Hot Jupiter has been found in a system with a Super-Earth and an icy giant.
