Obviously those bodies' atmospheres that are more "proper" ones, more than an exosphere or thin thermosphere, are mentioned in bold. Shouldn't Io's atmosphere be in bold too? It can reach up to 40 nbar pressure. Io's atmosphere is a collapsible one, but so is Pluto's too which is in bold in the template. At what surface air pressure is the border set between a "proper" atmosphere and a thin one?212.186.15.63 (talk)10:03, 31 May 2020 (UTC)[reply]

There is a difference between microbars and nanobars.Ruslik_Zero20:24, 31 May 2020 (UTC)[reply]

Aw, really? Again, where do you set the pressure border? Do you set it at 1 microbar?212.186.15.63 (talk)05:06, 1 June 2020 (UTC)[reply]
