Шаблон:Mp is a near-Earth object roughly Шаблон:Convert in diameter discovered by Grzegorz Duszanowicz and Jordi Camarasa. The object orbits the Sun but makes slow close approaches to the Earth–Moon system. Between 11 June 2022 and 3 July 2022 (a period of Шаблон:Time interval) it passed within Earth's Hill sphere (roughly Шаблон:Convert) at a low relative velocity and became temporarily captured by Earth's gravity, with a geocentric orbital eccentricity of less than 1[1] and negative geocentric orbital energy.[2] Due to its Earth-like orbit, the object might be of artificial origin or lunar ejecta.[3] However, visible spectroscopy obtained with the Gran Telescopio Canarias shows that it is an asteroid.[4] The closest approach to Earth in 2022 was 26 June 2022 at roughly Шаблон:Cvt when it had a relative velocity of Шаблон:Convert.[5] It was last near Earth around 16 January 1981 when it passed about Шаблон:Cvt from Earth.[5] It will return as a temporary satellite in December 2051.[2][4]

The object was discovered on 2 July 2022 by Moonbase South Observatory in Namibia when it had a deep Southern Hemisphere declination of –59° in the constellation of Pavo.[3]
With a 56-day observation arc the object shows a 1.2% chance of impacting Earth between the years of 2075–2122.[7] This asteroid experienced a temporarily-captured flyby in 1981, had another one in 2022, and the current observation arc predicts it will become a mini-moon again in 2051.[2][4]
The reflectance spectrum of 2022 NX1 suggests that its origin is not artificial and also that it is not lunar ejecta;[4] it is also different from the V type of the only other mini-moon with available spectroscopy, Шаблон:Mpl. The visible spectrum of 2022 NX1 is consistent with that of a K-type asteroid, although it could also be classified as an Xk type.[4] Considering typical values of the similar albedo of both K-type and Xk-type asteroids and its absolute magnitude, 2022 NX1 may have a size range of 5 to 15 m.[4]
