Object data of NGC4151

Object type: Galaxy (SBab)
Size: 6.8' x 5.3'
Magnitude: 11.1 mag
Constellation: CVn
Distance: 60 Mio Ly
Notes: NGC 4151 is a spiral galaxy with a weak inner ring structure located 60 million light-years from Earth in the constellation Canes Venatici. It is one of the nearest galaxies to Earth that contains an actively growing supermassive black hole.

To the north one can find the small spiral galaxy NGC 4156 in a distance of 260 million light-years. A tidal tail is connected with NGC 4156.

A supernova is also visible in the above image (SN 2018aoq in NGC 4151). The position is indicated in the object identification image. The gif animation switches between one luminance exposure before the supernova explosion (2018-03-15) and another luminance exposure after the supernova explosion (2018-04-19).

Five distant galaxy clusters are visible in the image:

  • GxCl 01 (z=0.220): XMMXCS J1209.4+3928
  • GxCl 02 (z=0.341): WHL J121115.3+391137
  • GxCl 03 (z=0.260): WHL J120952.6+393736
