Description

1996 XB₂₇ is classified as an Amor asteroid because its perihelion is less than 1.3 AU and does not cross Earth's orbit. The asteroid is on a low-eccentricity and low-inclination orbit between the orbits of Earth and Mars. This is within a region of stability where bodies may survive for the age of the Solar System, and hence it may have formed near its current orbit.^[4]

It orbits the Sun at a distance of 1.1–1.3 AU once every 1 years and 4 months (474 days; semi-major axis of 1.19 AU). Its orbit has an eccentricity of 0.06 and an inclination of 2° with respect to the ecliptic.^[1] The body's observation arc begins with its official discovery observation at Kitt Peak in December 1996.^[2]

Between 1900 and 2200 its closest approach with Earth is more than 0.11 AU.^[5]
