Slow rotation not working

Hi,

I am trying to make a planet rotate at a somehow slow rate - about one revolution per 300 seconds. But I tried timelines, interps, rotating movement component etc. and cannot get even near that speed. The planet simply stops rotating after reaching around one revolution per 15 seconds.
Is there a way to make the planet rotate slowly?

And I don’t want to achieve that through animation, because I need to have the actor itself rotate.

HI!

It think Timeline node is enough.

And with these parameters of curve, I got very slow rotation

Oh, I must have done something wrong previously then, because this works now.
Nevertheless, now that I see how fast it rotates I think I would need a revolution every about 2000 seconds to make it look a bit more real.
And if I make a timeline with the second point (2000; 360) the rotation seems bumpy as if the smallest possible time increments in a timeline was not, in fact, small enough.
