It is presumed that planets are changing orbital speed at exceedingly slow rates and it will take millions of years for any significant alteration in the "balance" of orbits in the solar system. This theory has recently been confounded.
Venus was thought to be in a fixed orbit of 243.0185 days, but when astronomers went looking for it, it was found 20 kilometers further back than it should have been. Calculations showed the orbit had slowed by 6.5 minutes.
This will mean that computer computations will have to be altered for future planetary probes to Venus. This is a drastic rethink for scientists. For some reason Venus is affected more by fierce weather conditions and planetary gravitational interaction than other planets.
There could be a simpler explanation. Venus could be travelling at different rates in its orbit due to getting close to other planets. It could be a normal slow down period.
