Interesting fact for #science #astronmy and #sciencefiction #writers and #authors. A Jupiter-class planet does not get proportionally wider with greater mass, it gets denser and maybe a little wider. Red dwarfs, which are what happens with a Jupiter-class planet gets massive enough the fuse deuterium, may actually be less wide than Jupiter. One such example is 61 J-mass but .89 J-radius!

You want to get this correct. I've read articles that conflate mass and radius, and that renders the article ridiculous. Here is a very interesting article on the subject here:

Why bring this up? A furnace-hot brown dwarf with an angry red glow is front and center (or in the middle of) one of my #sff stories. Would worlds orbiting it be planets or moons?

Apprentissage de #Mastodon suite : vu qu'on peut se créer des colonnes par hashtag (#astronmy ou #space par exemple), je pense qu'il est utile de bien choisir les hashtags à ajouter à ses pouets :) Je pense que c'était déjà possible sur le site de l'oiseau, mais je ne l'ai jamais utilisé de cette façon. Mes listes/colonnes étaient constituées de comptes, et donc ne concernaient pas une thématique exclusive.
