Your 10mm will give 75x mag which is not enough for planetary work.
You need something in the 4, 5, or 6mm range, which would give
187, 150, and 125x respectively.
You will see nice images of Saturn and Jupiter at 75x, but they will
be very small, and hence not very satisfying.
If your scope came with a 2x Barlow lens you could use that with your 10mm eyepiece which would give 150x mag.

I see Aidan has already told you much of what I said.
