It's not a direct proportion.
The square of the period is proportional to the cube of the planet's distance from the Sun.
(More accurately, the length of the semi-major axis of the orbital ellipse.)

The answerer above is wrong. It does not involve the mass.
It is purely based on its mean distance from the sun.
Eg an artificial satellite put into Mars orbit around the sun, will orbit in the same time as Mars.
Look up Johann Kepler on Wikipedia. He worked all this several hundred years ago.

YES.
And it is also affected by the mass of the planet, and its speed of travel.
