The planets and the Sun orbit around each others common center of gravity referred to as the barycenter. Think of the planets as free falling objects. The Earth, as all of the other planets, are actually falling toward the center of the Sun's gravity. That is to say, for every one foot they fall toward the Sun, the Sun moves one foot out of the way.

What kind of orbit would neptune have according to Keplers harmonic law?
Kepler's first law says Neptune has an elliptical orbit with the Sun at one focus. The same goes for the other planets.
Who developed the law of universal gravitation that explains the orbit of the planets?
Galileo
Do stars orbit planets or planets orbit stars?
Planets orbit stars.
Do all the planets have smaller planets orbiting them?
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
What is the importance of Newton's law of gravitation?
It explains why the planets remain in in orbit around the sun. Also, why moons orbit their planets. It also explains why humans remain on earth.
What type of orbit do the planets have to revolve around the sun?
According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre.
What is is the importance of newton's law of universal gravitation?
It explains why the planets remain in in orbit around the sun. Also, why moons orbit their planets. It also explains why humans remain on earth.

How many moons do the suns have?
The Sun has no moons. Moons orbit Planets > Planets orbit the Sun.
How fast do the planets orbit the earth?
The planets do not orbit the Earth, they orbit the sun.
What natural forces and law that keeps the planets in their orbit?
Gravitational forces as described by Newton's Universal Law of Gravitation. Also important is the inertia of the planets and Newton's First Law of Motion is involved there.
Do the stars orbit the planets or do planets orbit stars?
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
