Making objects spin at a really slow rate

Here is my code…

var spinx : int =0; var spiny : int
=0; var spinz : int=0;

function Update () {
transform.Rotate(spinx,spiny,spinz); }

I am simulating space and spinning the planets, but the value 1 makes the objects still even spin too fast. Is there another way to spin it but just at a really slow rate?

Rotate() ( and pretty much every other method in Unity) takes float as parameters, not INTs. So you can use values like 0.1f, 0.01f etc.
