Sumerian instructions for its observation, fully discussed in The 12th Planet, indicate that relative to the ecliptic it arrived from the southeast, from under the ecliptic; formed an arc above the ecliptic; then plunged back below the ecliptic in its journey back to where is had come from.

In spite of official denials, a disclosure did leak out at the end of the year . It came in the form of an exclusive interview of the key IRAS scientists by Thomas O'Toole of the science service of the Washington Post. The story, generally ignored - suppressed, perhaps - was carried by several dailies. ... The opening paragraphs of the exclusive story began thus:
WASHINGTON - A heavenly body possibly as large as the giant planet Jupiter and possibly so close to Earth that it would be part of this solar system has been found in the direction of the constellation Orion by an orbiting telescope called the Infra-red Astronomical Observatory (IRAS).

By concluding that the inclination of Planet X might be as high as 30 degrees, modern astronomers corroborated Sumerian astronomical data. So does the most recent determination that the planet is orbiting toward us from the southeast, the direction of the constellation Centaurus. Nowadays we see there the constellation Libra; but in Balylonian/biblical times that was the place of Sagittarius.

In this regard it is pertinent to quote the biblical verses from the Book of Job that describe the appearance of the Celestial Lord and its return to its distant abode:
Alone He stretches out the heavens and treads upon the farthest Deep.
He arrives at the Great Bear, Orion and Sirus and the constellations of the south. ...
He smiles his face upon Taurus and Aries;
From Taurus to Sagitarrius He shall go.
It is not just an arrival from the southeast (and the return thereto) but also a description of a retrograde orbit.
