Time Dilation & Mass: Does 2x Mass Mean 2x Slower Time?

[k!rl]

I was wondering if time on a planet which is exactly twice the mass of the Earth would pass exactly twice as slow relative to Earth time?

So after a year on this big earth, two years would have passed on earth?

Thanks

No, by this reasoning time would pass infinitely fast in the absence of a mass. Please see https://en.wikipedia.org/wiki/Gravitational_time_dilation for how to describe gravitational time dilation.
