Discovered through gamma-ray burst mapping. Largest-known regular formation in the observable universe. [8] Huge-LQG (2012–2013) 4,000,000,000 [9] [10] [11] Decoupling of 73 quasars. Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "The Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion ...
The Hercules–Corona Borealis Great Wall (HCB) [1] [5] or simply the Great Wall [6] is a galaxy filament that is the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion light-years in diameter).
The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. [58] Asteroid spectral types are mostly Tholen, but some might be SMASS.
From the biggest asteroid to the biggest black hole, check out some of the objects almost too big to imagine. ... This quasar group is 4 billion light-years across, the largest in the universe ...
At its discovery, it was identified as the largest and the most massive known structure in the observable universe, [1] [2] [3] though it has been superseded by the Hercules–Corona Borealis Great Wall at 10 billion light-years. [4] There are also issues about its structure (see Dispute section below).

Researchers estimate that it could contain somewhere between 1,000 and 10,000 trillion stars.
The largest asteroids with an accurately measured mass, because they have been studied by the probe Dawn, are 1 Ceres with a mass of (939.3 ± 0.5) × 10 18 kg, and 4 Vesta at (259.076 ± 0.001) × 10 18 kg. The third-largest asteroid with an accurately measured mass, because it has moons, is 87 Sylvia at (14.76 ± 0.06) × 10 18 kg.
