And that sounds like a lot, but we suspect that there are around a trillion exoplanets in the Milky way galaxy.

这听起来很多 但我们怀疑银河系中有大约一万亿颗系外行星。

Because of these collisions, there may exist around 100 red dwarf stars in the entire milky way galaxy at this point.

由于这些碰撞，目前在整个银河系中可能存在大约 100 颗红矮星。

It is estimated that the milky way galaxy has as many as 400 billion stars and more than 100 billion planets.

据估算银河系的恒星可多达四千亿个，而行星可多达一千亿个。

On this scale, the milky way galaxy would be about as big as North America, and that's just our galaxy!

在这个尺度上， 银河系大约和北美一样大，而那只是我们的银河系！
