(126154) 2001 YH140, also written as (126154) 2001 YH140, is a resonant trans-Neptunian object discovered on December 18, 2001 by C. A. Trujillo, M. E. Brown.

Orbit and rotation

(126154) 2001 YH140 is locked in 3:5 mean motion resonance with Neptune.[4] When it makes three revolutions around the Sun, Neptune makes exactly five. The rotation period of 2001 YH140 is estimated to be 13.25 ± 0.2 hours.[5]

Physical characteristics

In 2010 thermal flux from 2001 YH140 in the far-infrared was measured by the Herschel Space Telescope. As a result its size has been estimated to be 300–390 km.[4]
