To get a sense of the distances involved with Aries, here's what we can say:
* The closest star in Aries is Hamal (Alpha Arietis), which is about 66 light-years from Earth.
* The furthest star in Aries is about 1,000 light-years away.
So, while we can talk about the distance of individual stars in Aries, we can't assign a single distance to the constellation itself.
