52975 Cyllarus /ˈsɪlərəs/, provisionally known as 1998 TF35, is an asteroid discovered on October 12, 1998, by Nichole Danzl at the Kitt Peak Observatory near Sells, Arizona in the United States. It is named for the centaur Cyllarus of Greek mythology.
In November 2009, Mike Brown and his team using the Keck telescope took a spectrum of Cyllarus (apparent magnitude 23), giving it "the record for the faintest spectrum of a Kuiper belt object".
Cyllarus came to perihelion in September 1989.[1]
