How far is the farthest known galaxy?

MACS0647-JD is a the farthest known galaxy till date, based on a photo metric red shift estimate, at a red shift of about z = 10.7,equivalent to a light travel distance of 13.3 billion light-years (4 billion parsecs).

I'm sorry,but most of the details you want are not available even on NASA's website, I collected as much as i could.

-Group/Cluster : MACS Jo67+7015
-Red Shift : 10.7
-size :  Less then 600 ly (Lightyears).
-shape : Unknown
-Mass : Unknown
-number of stars : 1 billion
-luminosity : Unknown
-black hole diameter : Unknown
-speed : Unknown
-distance from neighbor galaxies : Unknown

Our universe is 13.7 billion years away therefore to that extent we can see the 13.7 billion old light traveling to our Hubble telescope. MACS1149-JD (PCB2012 3020) is one of the farthest galaxy observed till the date that shows the light after the Big Bang that is 500 million years. To clear the writing in other words it means the light we see in Hubble was imitated at the 500 million years old age of our universe and from Hubble we are seeing 13.7 billion years away you may think it is past. The 13.7 billion years are just the prediction and not very accurate.

This galaxy is 200 million years old as predicted in 2015.
Good news for you is in 2018 as Nasa 2015 argued that “Hubble and Spitzer, NASA's James Webb Telescope, which is scheduled for launch in 2018. The newly described distant galaxy will likely be a prime target.”
Nasa 2015 also stated that “the galaxy has a redshift, or "z," of 9.6. The term redshift refers to how much an object's light has shifted into longer wavelengths because of the expansion of the universe. Astronomers use redshift to describe cosmic distances.” you may also be interested in this research paper about dark matter focusing on Warm Dark Matter with Lensed High-redshift Galaxies and three strongly lensed images of Candidate z 11 Galaxy. This galaxy namely MACS1149-JD is a dwarf, mass 1x109 Mo and size is approximately 10,000 light years by NASA 2015. Other information is yet to be discovered.
