Шаблон:Mp (or simply Шаблон:Mp) is a stony near-Earth asteroid of the Apollo group, with a diameter of about Шаблон:Convert. It was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) survey at Socorro, New Mexico on 3 February 2001.[1] It is an upcoming flyby target of JAXA's Hayabusa2 extended mission, which will approach less than Шаблон:Cvt from the asteroid in July 2026.[2][3]

Physical characteristics

Near-infrared spectroscopy of Шаблон:Mp in 2023 shows that it is a stony S-type asteroid composed of silicates, with traces of pyroxene on its surface. These findings disprove earlier suggestions of an L-type asteroid spectrum, which lack pyroxene absorption bands by contrast.[4]

Rotation and light curve

Шаблон:Mp's rotation period was first measured through photometric light curves in January 2002, which showed a periodicity of 5.02 hours.[5] Observations in 2003 and 2022 secured this period and refined it to Шаблон:Val hours.[6][7] Шаблон:Mp significantly varies in brightness by 0.8–1.1 magnitudes as it rotates, which indicates it has an elongated shape.[7][3]

In September 2020, a mission extension for JAXA's Hayabusa2 asteroid sample return probe was selected to do additional flybys of two near-Earth asteroids: Шаблон:Mp in July 2026 and a rendezvous with Шаблон:Mpl in July 2031.[2][3] Hayabusa2 will flyby within Шаблон:Cvt of Шаблон:Mp at a very high relative speed of Шаблон:Cvt, which will pose a challenge for the spacecraft's navigation and tracking capabilities during the encounter.[3]
