Object data of IC1613

Object type: Dwarf galaxy (dwarf Irr)
Size: 16.6' x 14.9'
Magnitude: 9.9mag
Constellation: Cet
Distance: 2.4 Mio Ly
Notes: The irregular dwarf galaxy IC 1613 is a member of the Local Group of Galaxies. It can be found inside the constellation Cetus in a distance of 2.4 million light-years. IC 1613 has played an important role in the calibration of the period luminosity relation of Cepheids for estimating distances, because an unusually low abundance of interstellar dust both within IC 1613 and along the line of sight enables especially accurate distance estimates.

Four distant galaxy clusters are also visible in the above image:

  • GxCl 01 (MCXC J0105.0+0201) with redshift z = 0.197 (light-travel time = 2.3 billion years)
  • GxCl 02 (NSCS J010328+022246) with redshift z = 0.280 (light-travel time = 3.1 billion years)
  • GxCl 03 (NSCS J010529+023128) with redshift z = 0.250 (light-travel time = 2.8 billion years)
  • GxCl 04 (NSCS J010525+023904) with redshift z = 0.140 (light-travel time = 1.7 billion years)
