Good and small Minecraft space modpacks?

I would like to install a Minecraft Modpacks, but I'm always looking for some that eat 8GB of Ram, so I'm looking for small ones. Do you have an idea?

You can put together one yourself, I do it often. Take one of the modpacks that you like and leave out all the mods that you don't necessarily need.

Can you then leave the cores for the mods in there or do they have to be removed?

You can make one yourself, the galacticraft mod and its extensions are worth a look

So for me the tekxit 3 modpack (150 mods) with 5-6 gb ram (8gb systemram) runs lagg free, there's also the galacticraft mod with it, although there are many other mods in it you can still have a look

They should stay in there, otherwise the mods no longer work.

I mean the ones you take out
