Question

Quizplus · Accepted Answer

Many of the extrasolar planetary systems discovered so far have jovian planets that are very close to their parent stars, which is quite different from what we observe in our own solar system. This is partly due to the limitations of our current detection methods, which are biased towards finding large, massive planets that are close to their stars. However, even with these limitations, we have still discovered many planetary systems that have unique and unexpected configurations.
