Neptune and Uranus are identical planets
The computational answer, which would assume identical ellipses for Earth and Saturn, and identical oribital speeds, is a period 10 times that of Earth. The actual "year" for the planet Saturn is 29.7 years.
There is not fifth planet on Earth, since Earth is a planet...
Earth does not have planets, it is a planet.
No, there are not moons or stars ON planet earth, but there are moons and stars around planet earth. == ==
No. Uranus is the twin planet of Neptune. The twin planet of Earth is Venus. There has also been a new planet discovered recently, 600 light years away, called Kepler-22b, which seems to be very identical to planet Earth.

No, the gravity of this planet will not be greater than that of earth. If the new planet has a mass equal to that of earth, its total gravity will be the same. There is a little ambiguity regarding 4 times earth density and half the earth's diameter if the idea is to keep the mass of this proposed planet the same as the earth. But setting that aside and assuming that the mass of the new planet is the same as earth's, the gravimetric field will be the same. Gravity is proportional to mass, and identical mass yields identical gravity. Now to the good part! The surface gravity of the new planet will be considerably higher than the surface gravity of earth. Both planets have the same mass and the same gravity, but a person standing on the surface of the new planet will be experiencing a whole lot more force pulling on him. All the mass of the new planet is beneath this person, but he's a lot closer to the center of gravityand will weigh a whole lot more.

Earth.
The earth is the only planet on earth.
The planet after the Earth is Mars.
the planet after earth is mars
Earth is the third planet from the sun.
Planet Earth - about 80%.
