Appearing as strings of orange dots, the brightest sets of dots belong to asteroids Klotho and Lina. Both orbit out in the main asteroid belt between Mars and Jupiter, while smaller, more distant asteroids can also be seen passing through the image.

These asteroids were imaged by NEOWISE, the asteroid-hunting portion of the Wide-field Infrared Survey Explorer (WISE) mission. NEOWISE harvests measurements of asteroids and comets from the WISE images and provides a rich archive for solar system objects.

最亮的点集显示为橙色的点串,属于小行星克洛霍(Klotho)和丽娜(Lina)。这两颗小行星都在火星和木星之间的小行星带轨道上运行,同时也可以看到更小、更远的小行星穿过这张图片。

这些小行星是由NEOWISE拍摄的,NEOWISE是广域红外探测探测器(WISE)任务的小行星搜寻部分。NEOWISE从WISE图像中获取小行星和彗星的测量数据,为太阳系天体提供了丰富的档案。
