Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.
See NGC 7042 and Constellation
Epoch (astronomy)
In astronomy, an epoch or reference epoch is a moment in time used as a reference point for some time-varying astronomical quantity.
See NGC 7042 and Epoch (astronomy)
Light-year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.
New General Catalogue
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. NGC 7042 and New General Catalogue are NGC objects.
See NGC 7042 and New General Catalogue
NGC 7043
NGC 7043 Is a barred spiral galaxy located about 200 million light-years away in the constellation of Pegasus. NGC 7042 and NGC 7043 are NGC objects, Pegasus (constellation) and UGC objects.
Pegasus (constellation)
Pegasus is a constellation in the northern sky, named after the winged horse Pegasus in Greek mythology.

Principal Galaxies Catalogue
The Principal Galaxies Catalogue (PGC) is an astronomical catalog published in 1989 that lists B1950 and J2000 equatorial coordinates and cross-identifications for 73,197 galaxies.
See NGC 7042 and Principal Galaxies Catalogue
Spiral galaxy
Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae (pp. 124–151) and, as such, form part of the Hubble sequence. NGC 7042 and Spiral galaxy are spiral galaxies.

Type Ia supernova
A Type Ia supernova (read: "type one-A") is a type of supernova that occurs in binary systems (two stars orbiting one another) in which one of the stars is a white dwarf.
See NGC 7042 and Type Ia supernova
Uppsala General Catalogue
The Uppsala General Catalogue of Galaxies (UGC) is a catalogue of 12,921 galaxies visible from the northern hemisphere. NGC 7042 and Uppsala General Catalogue are UGC objects.
See NGC 7042 and Uppsala General Catalogue
William Herschel
Frederick William Herschel (Friedrich Wilhelm Herschel; 15 November 1738 – 25 August 1822) was a German-British astronomer and composer.
