Compared with Mercury (whose orbit, within our planetary family, is the most egg-shaped and tilted), the paths of the four outer giant planets ... matching simulations had the planet-like object ...

For example, an inner planet can orbit exactly twice for every one orbit of an outer planet. This is a 2:1 resonance, and like pushing a child on a swing amplifies how fast they swing, the ...

Exoplanets have captured the imagination of the public and scientists alike and as the search continues for more, researchers ...

Recent studies have revealed that, until now, Hot Jupiters seem to be the only planet in orbit around their host star. This ...

Right now, the outer planets are all on relatively the same side of the system. As a result, we can enjoy a planetary parade every time the inner planets make a lap. In the early evening, look to the ...

A new understanding of planet formation The discovery of an outer cold giant planet and an inner Super-Earth adds another layer of complexity to the WASP-132 system. The standard hypothesis of ...

The discovery of an outer cold giant planet and an inner Super-Earth adds another layer of complexity to the WASP-132 system. The standard hypothesis of migration by dynamical perturbation of the ...
