Resource Storage Capacity

Is there a cap on the amount of resources you can store on a planet?
I just got about 900K crystal delivered to one of my planets and it was like 50K above the storage capacity, but the crystal was on the planet. Does this mean in theory it's possible to store infinite amounts of resources on a planet as long if it's transported there from other planets?

This would save me some trouble with building up new colonies and such

you can have more than what your storage can handle but at a cost if you go into the red your planet mines can no longer work you can add more storage too keep yourself from going into the red

yea you technically can store an infinite amount of resources on a planet, thing is thats not a good idea based on what taz said. also you are at risk of attack.
