Question: what planet do you think is under the worst conditions.

I have two answers. Earth is under threat due to global warming and other ways in which human’s are exploiting its natural resources, both for profit and due to ignorance/carelessness. If we don’t change our behaviour we could make our only planet inhabitable. Neptune has extreme weather. It’s storms can reach speeds of 2100km/hour almost ten times the fastest hurricanes on Earth (225km/hour). I’m sure than some planets outside of our solar system have even more extreme conditions. I always find it amazing looking at photos of lightning on other planets, look at Jupiter storms here: https://www.nasa.gov/feature/jpl/juno-solves-39-year-old-mystery-of-jupiter-lightning .
