The orbital eccentricity of an astronomical body is the amount by which its orbit deviates from a perfect circle, where 0 is perfectly circular, and 1.0 is a parabola, and no longer a closed orbit.
The eccentricity value measures how non-circular an orbit is. The planets in decreasing order of eccentricity with their approximate eccentricity values are: # Pluto: 0.25 # Mercury: 0.21 # Mars: 0.093 # Saturn: 0.056 # Jupiter: 0.048 # Uranus: 0.047 # Earth: 0.017 # Neptune: 0.0086 # Venus: 0.0068
The path is called the orbit. There are 8 planets (excluding Pluto and the other dwarf planets) with separate paths at various unique distances from the Sun.The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune (in order of increasing distance from the Sun).The path that a planet takes while traveling around the sun is called its orbit. Mercury has the fastest orbit, at 88 days. Neptune has the longest orbit, at 165 years.

Actually, this is why planets orbit the sun, but not why they don't fall into it. It is the motion of the planets that keeps them from falling into the sun. Since the solar system formed from a spinning gas cloud that began to spin faster and faster as gravity squished it (gravity pulls toward the center...which is why planets and stars are round) all the planets spin around the sun (orbit) and rotate on their axis. Smaller planets close to the sun spin more slowly, because the sun's gravity has gradually slowed them down. This is also why the moon always has the same side facing the earth.Another Viewpoint:The planets have their own velocity. This combines with the Sun's gravity to produce a stable orbit around the Sun.
Earth has an average eccentricity in its orbit of 0.0167. This compares with 0.0068 for Venus and 0.205 for Mercury, which are the minimum and maximum eccentricities in the eight planets. So, the Earth's orbit is not too far from circular. In order of increasing eccentricity, the list of planets is: Venus Neptune Earth Uranus Jupiter Saturn Mars Mercury.

Gravitational force is what holds all the planets in their orbits around the sun. This force is determined by the mass of the objects and the distance between them. The gravitational pull of the sun keeps the planets in their respective orbits.
No planets fulfill that criteria.
Near (in order from closest to farthest): Mercury, Venus, Earth, and Mars Far (same order as before): Jupiter, Saturn, Uranus, and Neptune. Why? I suppose that's just how things worked out when the planets formed from the "protoplanetary disk". The planets have to be spaced apart enough to form stable orbits. Otherwise their mutual gravitational attraction could disrupt their orbits.
The planets in our solar system are arranged in order from the sun as follows: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The inner planets (Mercury, Venus, Earth, Mars) are rocky terrestrial planets, while the outer planets (Jupiter, Saturn, Uranus, Neptune) are gas giants.
As of 2017, it depends on whether you count major planets only, or all planets.The 8 major known planets in order from the Sun are:MercuryVenusEarthMarsJupiterSaturnUranusNeptuneIf you list ALL 13 known planets in order, including dwarf planets, they are:MercuryVenusEarthMarsCeresJupiterSaturnUranusNeptunePlutoHaumeaMakemakeErisDwarf planets also fall under the category of minor planets, of which there are thousands in our solar system. As of 2017, the orbits of 734,274 minor planets were archived at the Minor Planet Center, 496,815 of which had received permanent numbers. The largest minor planet that is not considered to be a dwarf planet is Sedna.
The planets rotate around the sun in the same order because they all formed from the same spinning disk of gas and dust in the early solar system. This disk had a consistent rotation direction, which was inherited by the planets as they formed. The gravitational pull of the sun keeps the planets in their orbits in this same order.

There is no 'phrase' or mnemonic for this because the order of the Sun, Earth and Moon changes as the Moon orbits the Earth. Remember - planets obit a star (the Sun is a star) - Earth is a planet moons orbit planets - The Moon is a moon.
None are in the corect order.In order of increasing distance from the sun, the following is the order of planets, dwarf planets and natural satellites that were mentioned in the question.MercuryVenusEarth (with the Moon)MarsJupiterSaturnUranusNeptunePluto
