Object data of NGC5899

Object type: galaxy (SBc)
Size: 3.3' x 1.4'
Magnitude: 12.5 mag
Constellation: Boo
Distance: 118 Mio Ly
   
Notes: NGC 5899 builds a non-interacting pair with NGC 5900.  But the above image shows some signs of interaction in NGC 5899 (better visible in the inverted image). East of NGC 5899 one can see a loop. The faint galaxy SDSS J151510.91+420334.6 seems to be a part of this loop. So, maybe this loop is a stellar stream.

Also NGC 5900 shows some interesting structures in the inverted image.

The galaxy group near the bottom right corner of the above image, consisting of NGC 5893, NGC 5895 and NGC 5896 is listed as Holmberg 701 in the Catalogue of Double and Multiple Galaxies.

The brightest members of the galaxy cluster NSCS J151456+420852 (distance = 3.6 billion light years) are clearly visible, as indicated in the object identification image.
