Physical Information: Based on a recessional velocity of 4550 km/sec (and H 0 = 70 km/sec/Mpc), NGC 1 is about 210 to 215 million light-years away, in good agreement with redshift-independent distance estimates of 175 to 245 million light-years. (Another recessional velocity measurement of 2215 km/sec would place the galaxy only about 100 ...

ngc 1是一个相互作用星系，星等为13.40等，位于飞马座，距离地球190000000光年，直径约为90000光年，小于银河系。 它是星云和星团新总表中的第一号天体。

NGC 1 is a spiral galaxy of the morphological type SAbc. The escape speeds measured since the year 2000 are in the range of 4550 km/s to 4620 km/s, the resulting distances from 64 Mpc to 74 Mpc (209 to 241 million light years).

NGC 1 is a Spiral Galaxy in the Pegasus constellation. NGC 1 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 13.4, NGC 1 is visible with the help of a telescope having an aperture of 10 inches (250mm) or more.
