| Object type: | galaxy (S0) | |
| Size: | 11'x2' | |
| Magnitude: | 10.5 mag | |
| Constellation: | Vir (near border to Hya) | |
| Distance: | 80 Mio Ly | |
| Notes: |
NGC 5084 is a lenticular galaxy in the constellation
Virgo, located near the border to constellation
Hydra. It is a member of the Virgo II groups of galaxies, which are the
long southern extension to the Virgo cluster. Carignan et al determined the mass of NGC 5084 in 1997 by analyzing the spectra of the satellite galaxies. They confirmed 9 satellite galaxies, from which 8 are visible in the above image and indicated in the object identification image with designation G2 ... G9. Galaxy G8 appears to be satellite of galaxy G7 (ESO 576-40). So, this galaxy is a satellite of a satellite! The estimated mass of NGC 5084 is 1e13 solar masses, what makes this galaxy to one of the most massive disk galaxy known. |
