the sun is a star not a planet
No. The link is between the planet's distance from its star and the period of its orbit.
No - a star is a star and a planet is a planet. See related questions.
They both have different planets. They do not have a planet that is on both!
Universe -> galaxy -> star -> planet
A planet orbits a star whereas a moon orbits a planet.
