| DETAILS | Companion galaxies. NGC6438 is a lenticular galaxy i.e. possessing both spiral and elliptical properties also classed as having a ring. NGC6438A is a ring galaxy where some deformation seems to have occurred. Some reults seem to suggest that this may be an interacting triplet, however the system is too complex to determine accurate data. |
