A region of gas and dust from exploding stars in the Milky Way galaxy starts to collapse under its own gravity, forming a small star surrounded by a disk of rocky material and gas.

银河系漩涡展开过程中某些区域的星群之气体尘埃在引力作用下，形成由岩石物质和气体包围的小行星。

Even Newtonian gravity works quite well within its domain (eg small velocities).

即使是牛顿引力工程领域内的比较好(如小速度)。

Considering Pluto's small size, it was a surprise to see that its gravity was strong enough to hold on to an atmosphere at all.

鉴于冥王星个头很小，看到其引力竟然足以“拴住”大气层很让人意外。

Since Eros's gravity is so small (a person on its surface would weigh only a few dozen grams), this dust probably could not have fallen into the craters in the way that it would on a heavier body.
