How far is it?

The Sloan Great Wall is a cosmic structure formed by a giant wall of galaxies (a galactic filament), and to the present day it is the largest known structure in the universe.
The 1.4 billion light-year long Great Wall structure was discovered by the Sloan Digital Sky Survey in 2003.

It depends on your criterion for "object". Of course entire galaxies can be considered objects, and the galaxies in the center of clusters (such as giant diffuse galaxies or brightest star clusters) can be gigantic, clocking in at several times the size of the Milky Way. Perseus A, which is 235 million light years away would be an example.
Obviously, this isn't the kind of "object" many people are looking for. They are wanting to know the size of the largest singular object in the world. That would most definitely be a star (if you don't count nebulae, which again some people may not). The largest known star is VY Canis Majoris at around 4500 lightyears away! It is a red hypergiant star in the Canis Major system, and it is HUGE. It is somewhere around 2000x bigger than the sun, which would make our fairly large sun a speck by comparison. If you dropped VY CM into our solar system, we would still be well inside of it here on Earth, and its surface would be somewhere between Mars and Saturn! Its large size also means it won't last long in galactic time, and I feel sorry for anyone who may be around it when fusion ends ;)

in terms of mass it would be a black hole. in terms of volume, a hypernova, and in terms of density then a pulsar. the nearest black hole is 1600 light years away. there are no hypernovas in the visible universe at the moment. the narest pulsar is 280 light years away

A giant piece of space turd that killed the man who pooped it out. It's on a mission to find a giant toilet but that's millennia away unless of course it starts to pick up the pace.

Currently, it is the Sloan Great Wall (of galaxies).
It is 1.37 billion light years long.

The galaxies- (I think)

I think its a black hole if im not mistaken
