Abstract

Images of the trans-Neptunian objects 1997 CQ₂₉ and 2000 CF ₁₀₅ obtained with the Hubble Space Telescope WFPC2 camera show them to be binary. The two components of 1997 CQ₂₉ were separated in our images by 0″.20 ± 0″.03 in 2001 November and by 0″.33 ± 0″.01 in 2002 June/July. The corresponding minimum physical distances are 6100 and 10, 200 km. The companion to 2000 CF₁₀₅ was 0″.78 ± 0″.03 from the primary, at least 23, 400 km. Six other objects in the trans-Neptunian region, including Pluto and its moon Charon, are known to be binaries; 1997 CQ₂₉ and 2000 CF ₁₀₅ are the seventh and eighth known pair. Binarity appears to be a not uncommon characteristic in this region of the solar system, with detectable companions present in 4% ± 2% of the objects we have examined.
