NGC 5101 is alenticular galaxy in theconstellationHydra. It is separated in the sky from thespiral galaxyNGC 5078 by about 0.5 degrees, and both are believed to be at the same distance from theEarth. This would mean they are approximately 800,000light-years apart. Both galaxies are believed to be about the size of theMilky Way.[3]
