Шаблон:Mp is a near-Earth asteroid, and at only Шаблон:Convert across and absolute magnitude 29.34 mag, it is thought to be the third smallest asteroid observed over multiple years, after Шаблон:Mpl with absolute magnitude 30.4 and Шаблон:Mpl with absolute magnitude 29.5. The asteroid is notable for reflecting about 60% of the light that hits it, making it one of the brightest near-earth asteroids ever seen.[1]
Discovered by the Catalina Sky Survey on 12 October 2015, it was observed with several ground-based telescopes.[2] Radar observations were also made using the Arecibo Observatory as it passed Шаблон:Convert from the Earth.[1] Observations suggest its surface composition is similar to Aubrite meteorites, a rare class of high-albedo differentiated meteorites.[2]
The albedo and radar polarization ratio suggest Шаблон:Mp belongs to the E-type asteroids, and comparison of its spectral and dynamical properties suggest it may have broke off of the 70-kilometer diameter E-type asteroid 44 Nysa.[2] Шаблон:Mp is also notable for its rather short rotation period of only about 2 minutes, which, combined with its low surface gravity makes it very difficult for Шаблон:Mp to retain a regolith layer. Its surface therefore most likely resembles a bare rock.[2]
