Here we use the Large Binocular Telescope (LBT) and the Lowell Discovery Telescope (LDT) to conduct a comprehensive physical characterization of quasi-satellite (469219) Kamo\u02bboalewa and assess its affinity with other groups of near-Earth objects. We find that (469219) Kamo\u02bboalewa rotates with a period of 28.3 (+1.8\/\u22121.3) minutes and displays a reddened reflectance spectrum from 0.4\u20132.2 microns. This spectrum is indicative of a silicate-based composition, but with reddening beyond what is typically seen amongst asteroids in the inner solar system. We compare the spectrum to those of several material analogs and conclude that the best match is with lunar-like silicates. This interpretation implies extensive space weathering and raises the prospect that Kamo\u2019oalewa could comprise lunar material.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Benjamin N.
