Matese and Daniel Whitmire say that the points of origin for long-period comets gives a pattern that suggests Tyche's existence. They noted that Tyche, if it exists, should be seen in the archive of data that was collected by NASA's Wide-field Infrared Survey Explorer (WISE) Infrared telescope.[3] However, several astronomers disagree that Tyche exists.[2][4] In 2014 NASA announced that WISE had not found such a planet.

Tyche is in the Nickelodeon TV show The Fairly OddParents. It is also called "Yugopotamia" and is where the character Mark Chang is from.
