According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus.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 the motion of one object around another?
In planetary terms, when referring to the motion of planets and moons etc. the motion is describes as orbiting. Moons are on orbit around planets, while the planets are in orbit around the sun. An orbital motion.
Does the sun travel around the planets or do the planets travel around the sun?
The planets travel around the sun.
What controls the motions of the planets?
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
What are the two kinds of movements made by planets?
Planets generally move in 2 ways:Revolution - they spin around their own center (this is what makes the Earth have a day.)Orbit - they spin around a star (Earth spins around a star called our Sun.) This in part causes our yearly seasons.
What men stated that planets move around the sun in an ellipse?
Johannes Kepler in his three laws of planetary motion
What two planets that retrograde motion around the sun?
Mercury and Venus are the two planets that retrograde motion around the sun.
What is the motion of one object around another?
In planetary terms, when referring to the motion of planets and moons etc. the motion is describes as orbiting. Moons are on orbit around planets, while the planets are in orbit around the sun. An orbital motion.
What is the difference between geocentric heliocentric and planetary motion?
Geocentric motion of planet is that in which earth is at the centre of the universe and all other planets revolving around it.Heliocentric motion of planets is that in which sun is the of universe and other planets revolving around it.In planetary motion all the planets includes Earth revolving around the Sun in their fixed orbit.
The famous scientist that made discoveries about the motion of the planets around the sun?
Galileo Gallie
How does the force of gravity affect the direction of motion of the planets?
earths rotation around the sun
What is the motion of a asteroid?
They basically move similar to planets and comets, i.e., in ellipses around the Sun.
Does the sun travel around the planets or do the planets travel around the sun?
The planets travel around the sun.
What controls the motions of the planets?
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
What is a good sixth grade science question for planets and their motion?
Well a good answer for that would be there are many different motions for different planets but if you want to know are universe planets motion it all rotates around the sun.
How could newton's first law of motion explain that a force is acting between the sun and its planets?
If no force, the planets would move in a straight line, not in a orbit around the sun.
What are the two kinds of movements made by planets?
Planets generally move in 2 ways:Revolution - they spin around their own center (this is what makes the Earth have a day.)Orbit - they spin around a star (Earth spins around a star called our Sun.) This in part causes our yearly seasons.
How often does Saturn move?
Saturn, as are all other planets, is in a constant state of motion around the Sun.
