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.
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 250 and Epoch (astronomy)
IRAS
The Infrared Astronomical Satellite (Dutch: Infrarood Astronomische Satelliet) (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths.
See NGC 250 and IRAS
Lenticular galaxy
A lenticular galaxy (denoted S0) is a type of galaxy intermediate between an elliptical (denoted E) and a spiral galaxy in galaxy morphological classification schemes. NGC 250 and lenticular galaxy are lenticular galaxies.
See NGC 250 and Lenticular galaxy
Lyon-Meudon Extragalactic Database
The Lyon-Meudon Extragalactic Database (LEDA) was a database of galaxies, created in 1983 at the Lyon Observatory.
See NGC 250 and Lyon-Meudon Extragalactic Database
Metre per second
The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second.
See NGC 250 and Metre per second
Morphological Catalogue of Galaxies
The Morphological Catalogue of Galaxies (MCG) or Morfologiceskij Katalog Galaktik, is a Russian catalogue of 30,642 galaxies compiled by Boris Vorontsov-Velyaminov and V. P. Arkhipova.
See NGC 250 and Morphological Catalogue of Galaxies
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 250 and New General Catalogue are NGC objects.
See NGC 250 and New General Catalogue
Pisces (constellation)
Pisces is a constellation of the zodiac.
See NGC 250 and Pisces (constellation)
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 250 and Principal Galaxies Catalogue
Sloan Digital Sky Survey
The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States.
See NGC 250 and Sloan Digital Sky Survey
Uppsala General Catalogue
The Uppsala General Catalogue of Galaxies (UGC) is a catalogue of 12,921 galaxies visible from the northern hemisphere. NGC 250 and Uppsala General Catalogue are UGC objects.
See NGC 250 and Uppsala General Catalogue
2MASS
The Two Micron All-Sky Survey, or 2MASS, was an astronomical survey of the whole sky in infrared light.
