摘要：

我们报告了1000多个近地天体的测量光谱特性，占目前发现的近地天体总数的5%以上。探测到的2.5微米以下的热通量使我们能够对包括两颗彗星在内的近50个物体进行粗略估计。报告了350多颗穿越火星的小行星的额外光谱数据。这些测量大多是通过麻省理工学院和夏威夷大学的研究人员之间的合作，并与美国航天局莫纳克亚火山红外望远镜设施充分合作完成的。我们称这个项目为麻省理工学院-夏威夷近地天体光谱调查（MITHNEOS; myth-neos）。

英文摘要：

We report measured spectral properties for more than 1000 NEOs, representing>5% of the currently discovered population. Thermal flux detected below 2.5 μm allows us to make albedo estimates for nearly 50 objects, including two comets. Additional spectral data are reported for more than 350 Mars-crossing asteroids. Most of these measurements were achieved through a collaboration between researchers at the Massachusetts Institute of Technology and the University of Hawaii, with full cooperation of the NASA Infrared Telescope Facility (IRTF) on Mauna Kea. We call this project the MIT-Hawaii Near-Earth Object Spectroscopic Survey (MITHNEOS; myth-neos).
