MCG +01-02-015 explained

MCG +01-02-015
Constellation Name:	Pisces
Epoch:	J2000
Type:	SB
Ra:	^[1]
Appmag B:	15.2
Z:	0.023640^[2]
Names:	LEDA 1852, CGCG 409-021, 2MASX J00302865+0551405, UZC J003028.7+055140

MCG +01-02-015 is a spiral galaxy in the constellation Pisces. It is an example of a void galaxy,^[3] and believed to be one of the most isolated galaxies known, with no other galaxies for around 100 million light-years in all directions.^[4]

Observational history

MCG +01-02-015 was previously classified as an elliptical galaxy of class E2 although higher-resolution imaging has revealed it to be a barred spiral galaxy.^[5]

Formation

It is theorised by many astrophysicists that void galaxies are the result of large galactic filaments being pulled on by the gravity of a neighboring super cluster out of the less densely populated areas. Galaxies such as MCG +01-02-015 are left behind by events such as these.^[6]
