CINCINNATI (WKRC) - We should have known by the name.

The planet Uranus stinks, according to a study in "Nature Astronomy".

The clouds in Uranus' upper atmosphere are composed largely of hydrogen sulfide which is the molecule that makes rotten eggs smell so bad.

Scientists made this discovery from roughly 1.6 billion miles away by observing Uranus' cloud cover with a spectrometer on Nasa's Gemini Telescope in Hawaii.
