Thanks n-FA. But I do not know how far away is a quasar at redshift range of 5.3 ≤ z ≤ 5.7. Thanks

Here's a handy calculator

Thanks n-FA. That is a cool site. I saved it. It calculated between 72 an 78 MLY.

Ah, not sure that calculator is doing the maths right.

The result given is 72-78 Gly, and I don't think that's correct. Not even for its 'current' distance.

ETA the hyperphysics website calculator gives it as about 13.29 - 13.39 Mly.

Thanks. I went to that site and you are correct. Did you do the calculations on the other site? Did they turn out like I said or did I do something wrong?

Thanks for your help. I like your site better because it worked for me. By the way, I thought it might be billions, but that made no sense to me!!

Sorry for the lame link. It appealed because of the many odd units but is apparently using a bad formula. Thanks to Gfamily for the better link.
