Planet position calculation using mean orbital elements ... The orbits of the major planets can be modeled as ellipses with the Sun at one focus. The effect of gravitational interactions between the planets perturbs these orbits so that an ellipse is not a exact match with a true orbit.

Newfound Planet Orbits Backward ; By Jeanna Bryner and Robert Roy Britt; posted: 12 August 2009; 09:56 am ET; ... A newfound planet orbits the wrong way, backward compared to the rotation of its host star. Its discoverers think a near-collision may have created the retrograde orbit, as it is called.

Orbit - Wikipedia, the free encyclopedia
In physics, an orbit is the gravitationally curved path of one object around a point or another body, for example the gravitational orbit of a planet around a star. Historically, the apparent motion...

The planets, their orbits, and their velocities are approximately in scale with each other, but the planet scale is much larger than than the orbit scale, and the sun is not in scale with either.

Planet hunters have discovered the biggest new world yet and it is going the wrong way around its home sun. The find is unique and astronomers say the planet must have flipped direction after a near miss with another huge passing body swung it around like a slingshot.

Astronomers with the Wide Area Search for Planets have discovered a planet, dubbed WASP-17, that is twice the size of Jupiter. That makes it the largest planet ever discovered. Unlike any other planet discovered so far, it orbits opposite to its star’s direction of rotation. ... 14 comments to "Giant Planet Orbits Backwards"

A team of scientists has found a new planet that orbits the wrong way around its host star. The planet WASP-17, which orbits a star 1,000 light-years away, was found by the United Kingdom's Wide Area Search for Planets (WASP) project in collaboration with Geneva Observatory in Switzerland.
