Orbit thumb|left|200px|2005 TB 190 is located near the "gap", a poorly understood region. 2005 TB 190 is classified as scattered-extended by the Deep Ecliptic Survey (DES), because its orbit appears to be beyond significant gravitational interactions with Neptune's current orbit. However, if Neptune migrated outward, there would have been a period when Neptune had a higher eccentricity. The aphelion of 2005 TB 190 lies at 104 AU. Simulations by Emelʹyanenko and Kiseleva in 2007 showed that 2005 TB 190 appears to have less than a 1% chance of being in a 4:1 resonance with Neptune. It has been observed 202 times over seven oppositions. It came to perihelion in January 2017. There are precovery observations dating back to November 2001. Physical properties + History of size estimates for 2005 TB 190YearDiameter (km)References2010372.5 37.52012464 622013507 127 116 In 2010, thermal flux from 2005 TB 190 in the far-infrared was measured by the Herschel Space Telescope. Initially, its size was estimated to lie within a range from 335 to 410 km. Upon further analysis, its size was estimated to be around 507 km mi. In the visible light, 2005 TB 190 has a moderately red spectral slope. The TNO was found in 2009 to have a rotation period of 12.68 ±3 hours, a common value for trans-Neptunian objects of its size. Similarly sized (120348) 2004 TY 364 has a rotation period of 11.7 ± 3 hours.
