Astronomers discover planet that shouldn’t be there



The discovery of a giant planet orbiting its star at 650 times the average Earth-Sun distance baffled researchers. So far, they haven’t been able to explain how such a strange system came to be.

The international team of astronomers was led by a University of Arizona graduate student. This is the most distant planet ever found orbiting around a single, sun-like star. As a sidenote, it is also the first exoplanet discovered at the University of Arizona.
The planet in case (HD 106906) has a mass 11 times bigger than that of Jupiter and is 650 times further from its star than the Earth is from the Sun. No currently known mechanism can explain how or why this is happening.
