The only real influence other planets could have is gravity.
Earth's gravity acceleration = 9.81 ms^-2
The closest planet is Mars. We'll take the closest distance between Mars and Earth.
s = rmars - rearth = 0,2278*10^12 - 0,1496*10^12
F = G * mobject * mmars / s^2
a = F / mobject
a = G * mmars / s^2 = 6,672*10^-11 * 0,642*10^24 / (0,2278*10^12 - 0,1496*10^12)^2 = 7,0045*10^-9
Now let's determine the gravitational influence of the sun:
a = G * msun / r^2 = 6,672*10^-11 *1,989*10^30 / (0,1496*10^12)^2 = 5,9296 * 10^-3
The sun's influence is a factor 5,9296 * 10^-3/7,0045*10^-9 = 846546 larger than the influence of the most nearby planet. The influence of the earth
is a factor 9,81/7,0045*10^-9 = 1400528232 larger than the influence of the most nearby planet.
You don't expect me to believe a planet as far as away and as light as Sedna influences anything at all. I'm with cmdrkeenkid against astrology.
