Valentin Ivanov (astronomer)

Valentin Ivanov and Ray Jayawardhana are two of the pioneers of the investigation of the planemos. They discovered the first double planemo Oph 162225-240515. This discovery came just before the debate about the 2006 planet definition, and posed the problem about the distinction between planets and brown dwarfs.
