Tyche (/ˈtki/) is the nickname given to a possible gas giant planet in the Solar System's Oort cloud. It was first proposed in 1999 by astronomer John Matese of the University of Louisiana at Lafayette. [1] [2] 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) telescope.[3] However, several astronomers disagree that Tyche exists.[2][4] It will take two years to look over the WISE data learn if WISE has actually found such a world or not.[5]
