Английская Википедия:(145480) 2005 TB190
Шаблон:Mp, provisionally known as 2005 TB190, is a trans-Neptunian object (TNO) with an absolute magnitude of 4.4.[1]
Orbit
Шаблон:Mp 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.[2] However, if Neptune migrated outward, there would have been a period when Neptune had a higher eccentricity. The aphelion of Шаблон:Mp lies at 104 AU.[3]
Simulations by Emel’yanenko and Kiseleva in 2007 showed that Шаблон:Mp appears to have less than a 1% chance of being in a 4:1 resonance with Neptune.[4]
It has been observed 202 times over seven oppositions.[1] It will come to perihelion in January 2017.[1] There are precovery observations dating back to November 2001.
Physical properties
In 2010, thermal flux from Шаблон:Mp in the far-infrared was measured by the Herschel Space Telescope. As a result, its size was estimated to lie within a range from 335 to 410 km.[3]
In the visible light, Шаблон:Mp has a moderately red spectral slope.[5]
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 Шаблон:Mpl has a rotation period of 11.7 ± 3 hours.
