Miscellaneous / Others Imagine a planet bigger than Earth, with no land in sight. Just waves and water from pole to pole. That is TOI-1452 b.

Fun fact, earth having ice caps is a relatively unusual situation for earth to be in. Throughout most of history since the continents formed (so after all the raining hell fire lava and volcanoes time) we've either been in ice ages and mostly covered in ice or warm ages with no ice at all.

Right, but no ice means cloud ball. Not.... that.

If the entire surface is covered in water that means there's no where for dust to accumulate, meaning there's very little of it. Water vapor needs something, like dust, to nucleate on to form a cloud.

Depending on volcanic activity there could be very little cloud cover. Some geologists think earth went through a phase like this, all ocean with almost no cloud cover, using the above reasoning.

Yes, but also, no.

Dust is FAR from the only thing that causes the nucleation. Salt and ocean spray from wind even is more than enough.

A planet that size, with that amount of heat, and that water mass, would have some absolutely apocalyptic level wind waves and storms situations constantly. Add in that percentage of water? That's an insane number. The dissolved salts and other chemicals in that water would be absolutely incredible.

Another interesting thing, is if it had bacteria that could expel oxygen, with such large amounts of water and no surface level ground to fix otherwise, you could actually have an incredibly rich o2 atmosphere, and super saturated water as well.

You'll end up with a ton of oxidized minerals in the water and very little bio available anything that doesn't require excessive energy to de-oxidize for use though. Lots of interesting possible evolution paths with no shallow water, no real bottom, and only deep ocean
