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 light years away. U1.11 LQG (2011) 2,500,000,000. Involves 38 quasars. Adjacent to the Clowes-Campusano LQG.
To help compare different orders of magnitude this section lists lengths between 10 −11 and 10 −10 m (10 pm and 100 pm). 25 pm – approximate radius of a helium atom, the smallest neutral atom. 30.8568 pm – 1 rontoparsec. 50 pm – radius of a hydrogen atom. 50 pm – bohr radius: approximate radius of a hydrogen atom.
Orders of magnitude (mass) An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe. Typically, an object having greater mass will also ...
To help try to put that into perspective, here are 10 of the biggest things of the universe in order of smallest to largest: 10. Ceres -- The biggest asteroid ever discovered by humans was found ...
A finite universe is a bounded metric space, where there is some distance d such that all points are within distance d of each other. The smallest such d is called the diameter of the universe, in which case the universe has a well-defined "volume" or "scale".
Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
Dark matter (26.8%) Dark energy (68.3%) [ 6] The observable universe is a ball-shaped region of the universe consisting of all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since ...
Widely recognised as being among the largest known stars. [44] R Horologii: 635 [84] L/T eff: A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun. 119 Tauri (CE Tauri, Ruby Star) 587 – 593 [85] AD ρ Cassiopeiae
