2006 BZ8 is a dark centaur and damocloid on a retrograde and highly eccentric orbit from the outer region of the Solar System. It was first observed on 23 January 2006 by the Catalina Sky Survey at the Catalina Station near Tucson, Arizona, United States. It has not been observed since 2008.[1] This unusual object is estimated around 9–23.5 kilometers (5.6–15 miles) in diameter.[5]

Notes
edit- ^ Linear fit of CSS V-band photometry using a phase slope of β = 0.054±0.008 mag per degree of phase angle.[5]
- ^ Two-parameter H-G modeling of V-band CSS photometry takes the opposition effect into account, yielding an absolute magnitude of H = 13.82±0.15 and a slope parameter of G = −0.12±0.10.[5]
