All Planets revolve around the Sun anti-clockwise as seen from the north, and differ in size, speed, velocity of axial rotation, etc. Their paths or orbits are not circular but elliptic. The Sun is their focus. Every orbit lies within 7° of the plane of the Earth's orbit except Pluto's (too distant to include in picture), which is inclined at 17°. Mercury takes 88, Venus 224, Earth 365 and Mars 687 days to complete their orbits. Jupiter takes approx. 12 years, Saturn 29, Uranus 84 and Neptune 165 years. Pluto takes 248 Years.
