These are the approximate calculations on which the timeline of the approaching Nibiru comet swarm are based. They involve the simple motion of a test comet orbiting the Sun with a 222 AU semi-major axis.
Calculating the position of the trailing and leading edges. The logarithmic distance between the orbits of Saturn and Uranus is log29.656 = 03.27. Saturn's orbital radius is assumed to be 9.58 AU. So the distance to the depicted Leading and Trailing Edges is scaled to the 3.27 value. Assume the Trailing Edge is 80% of that distance. Then, 0.80 x 3.27 = 2.616. The leading edge is at 1.198 of that 3.27 value or 36.6% of that value. Yaridanjo's model from expanded image data yields the following results.
The NEW measurements were obtained from this figure. This image represents the distance the comet swarm is as of 15 July 2008 (2008.625) when the crop circle was formed.
Our past estimates of the time it would take a comet at 2.8 AU (Asteroid Belt) to threaten Earth is either 95 or 80 + 95 = 175 days after 02/25/07. Comets with normal organic ices begin to glow at about the distance of the asteroid belt, or 2.8 AU. But if the orbit of this debris is representative of the threatening comets, they may pass near Earth orbit ~183 days later. The following is a list of the time and distance of the test comet both INBOUND and OUTBOUND. Note, delta is the amount that must be added to 2008.625 (15 July 2008) to obtain when events happen.
