All planets stink except Earth, if you're not in India, of course #space #sciencefacts #cosmos
11Remember, though, we humans have never smelled these planets directly - these are scientific speculations based on the known chemical elements and compounds present in each planet's atmosphere. Also note, that it's not advisable for any human to attempt smelling these atmospheres without proper protection due to their extreme conditions, which can be harmful or even fatal.
Mercury: As Mercury lacks a substantial atmosphere, it likely doesn't have a noticeable smell.
Venus: Venus has a thick atmosphere composed mainly of carbon dioxide, with clouds of sulfuric acid. While carbon dioxide is odorless, sulfur compounds typically have a pungent, rotten egg-like smell.
Earth: The smell of Earth's atmosphere can vary greatly depending on where you are. It can be fresh and green in forests, salty at the sea, or dusty in a desert.
Mars: The thin Martian atmosphere is also mostly carbon dioxide. Mars is known to have iron-rich rocks and soil, which, when ground up by Martian dust storms, could give the air a metallic scent.
Jupiter: The giant gas planet's atmosphere is predominantly hydrogen and helium, both of which are odorless. However, trace amounts of compounds like ammonia could add a sharp, pungent odor, similar to that of cleaning products.
Saturn: Like Jupiter, Saturn's atmosphere is mainly hydrogen and helium. The smell would be determined by minor components like ammonia, and possibly hydrocarbons, which might contribute a faintly sweet or gasoline-like aroma.
Uranus: This ice giant's atmosphere contains hydrogen, helium, and methane. Methane can have an odor, often associated with a swampy, organic smell.
Neptune: Neptune's atmosphere is similar to Uranus', so it would likely have a similar scent profile.
Remember, you'd need a spacesuit to visit these planets - and spacesuits don't allow smells to come through!
