This is a list of NGC objects 1–1000 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters, nebulae, and galaxies.Other objects in the catalogue can be found in the other subpages of the list of NGC objects.
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae.
Chupina — (Chupina objects 1 to 5 are located at and near open star cluster Messier 67 in Cancer) CIO — Catalog of Infrared Observations; CLUST — (open star clusters) CMC — Carlsberg Meridian Catalogue; Cn — Cannon (planetary nebulae) (Cn1 / Cn2 / Cn3) Cog — Cogshall (double stars) Col — Collins (double stars)
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.
Komberg–Kravtsov–Lukash LQG 5: 430,000,000: Discovered by Boris V. Komberg, Andrey V. Kravstov and Vladimir N. Lukash. [23] [24] Tesch–Engels LQG: 420,000,000: Shapley Supercluster: 400,000,000: First identified by Harlow Shapley as a cloud of galaxies in 1930, it was not identified as a structure until 1989.

An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. [1] In astronomy , the terms object and body are often used interchangeably.
An important uniform 5-polytope is the 5-demicube, h{4,3,3,3} has half the vertices of the 5-cube (16), bounded by alternating 5-cell and 16-cell hypercells. The expanded or stericated 5-simplex is the vertex figure of the A 5 lattice, . It and has a doubled symmetry from its symmetric Coxeter diagram.
General relativity is the geometrical theory of gravitation published by Albert Einstein in 1915/16. [ 9 ] [ 10 ] It unifies special relativity, Newton's law of universal gravitation , and the insight that gravitation can be described by the curvature of space and time.
