Starbrook is a ground-based wide-field optical sensor capable of surveying the increasingly large number of objects in the higher-Earth orbits, such as the geostationary and GPS-type orbits.

Starbrook是一个地面宽场光学传感器，能够测量高空地球轨道内数量上不断增加的物体，比如地球同步卫星和全球定位系统型轨道。

It shares this with a number of smaller asteroids whose orbits suggest they were spalled off in the collision, and with about 5% of the meteorites which fall to Earth.

灶神星和许多更小的小行星共同具有这种特征谱。这些更小行星的轨道表明它们是那次碰撞中剥落下来的，而其中大约5%的陨石落到了地球上。
