HCG35 is a sextet located in the constellation Lynx. The six galaxies have similar distances to Earth, in the range of approximately 750 million light-years. The group is dominated by early-type galaxies. Four out of six members are ellipticals or lenticular, with HCG35a and HCG35d being Spiral galaxies. The brightest galaxy (a) is also known as PGC 24601. It has an angular size of 0.41×0.17’ and an apparent magnitude of 16.2. All other galaxies are fainter, making this a very dim group of galaxies.
Details of all six galaxies are listed in the table below.
