Planet Nine is a hypothetical super-Earth-sized planet in the outer region of the solar system. In January 2015, a team of astronomers claimed to have discovered the giant Planet X orbiting the Sun based on mathematical calculations, with some astronomers questioning the idea that it exists.
Wow! Rowan-Robinson in a single author paper on “A search for Planet 9 in the IRAS data” with a candidate IRAS source. Expect several people running to their telescopes for a confirmation image. File under “Huge if true”.

Fun paper out today on the search for Planet Nine using old IRAS data. Nothing too compelling, but there is one candidate that Rowan-Robinson mentions, before mostly dismissing it as unlikely-to-be real. Still, if is fun to ponder: what if it IS real?https://t.co/daVnL4cZ61

The study used parameters consistent with the mystery planet and modern computing techniques, allowing the astronomer to determine three potential sources for the elusive planet from June, July and September of 1983. The revisited data points to the satellite having picked out an object moving across the sky in a region of space close to the galactic plane.

This data can then be used to try to figure out where this object might now be, while using other data sources, such as the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), launched in 2008.

“Dynamical studies are needed to check whether such an object is consistent with the ephemerides of other solar system objects and whether this object can account for the clustering of the orbits of Kuiper belt dwarf planets,” said Rowan-Robinson.
