Microplanetoid

I mean, the Fomalhauters weren't having enough problems with the repairs to their exhaust duct—their StarGrazer'd taken a hit from a rogue microplanetoid—then this earthbound yo-yo tries to put a goddam drift netter up their tailpipe.

The loose group of rocks, sand, random molecules, and microplanetoids known as the Hallelujah node was traveling in company around the Sun at a speed of eleven miles per second.

Around three hundred meters long and a little less than half as wide, the new shape was much smaller than the microplanetoid configuration.
