Recently, using data from the Japanese infrared telescope AKARI,  Dr. Amos Y.A. Chen and his collaborators published a paper in the Publications of the Astronomical Society of Australia which predicts the approximate positions of two massive Planet 9 candidates. To arrive at their conclusions this team carefully searched the AKARI observations for objects which over the course of months change their positions relative to distant stars and galaxies.   Further  observations are required to determine if either of these move like a Planet 9 or if instead they are some other type of distant astronomical object.
