The 1899 approach was missed, in 1910 a close pass with Jupiter increased the orbital period, in 1919 the path was off predictions and a "new" comet discovered by Sasaki (Kyoto Observatory, Japan) on October 25, 1919 was in fact discovered to be Finlay's.
In their respective pages, the Planets are listed along with their basic properties such as the year of planet’s discovery, mass, radius, orbital period, semi-major axis, eccentricity, inclination, longitude of periastron, time of periastron, maximum time variation, and time of transit, including all error range values.
13916 Bernolák, main belt asteroid with an orbital period of 1388
Examining, adapting and developing the work of Zecharia Sitchin, the book refers to the hypothetical Planet X, and suggests an orbital period of 3661 solar years with a return date in 2012.
Queloz performed an analysis on 51 Pegasi using radial velocity measurements (Doppler effect), and was astonished to find a planet with an orbital period of 4.2 days.
10835 Fröbel, a main belt asteroid with an orbital period of 1282.2174041 days
23070 Koussa, 23070 Koussa is a main belt asteroid with an orbital period of 2040.8963889 days (5.59 years).
2609 Kiril-Metodi, main belt asteroid with an orbital period of 1209
As first explained by Maximilian Schuler in a 1923 paper, a pendulum whose period exactly equals the orbital period of a hypothetical satellite orbiting just above the surface of the earth (about 84 minutes) will tend to remain pointing at the center of the earth when its support is suddenly displaced.
