The Solar System sounds like an extremely stinky place.
Cosmologists as of late found that the climate of Uranus has elevated amounts of hydrogen sulfide, an intensify that scents like spoiled eggs. The main direct record of the smell of another heavenly body originated from the Apollo space explorers, who asserted that Moon dust possessed an aroma like spent black powder. Mercury has an exceptionally meager climate thus would not have quite a bit of a smell by any means. Venus and Mars, much like Uranus, have considerable amounts of eggy hydrogen sulfide.
For Jupiter, the smell would rely upon where you were in the air. A few areas have high convergences of alkali (which smells like cleaning liquid), others hydrogen sulfide (eggs) and others hydrogen cyanide (severe almonds). Saturn and Neptune presumably don't have quite a bit of a smell since they're made primarily out of the scentless gases hydrogen and helium.
