NGC 5416 is a spiral galaxy and radio galaxy[1] located in the constellation Boötes. Its speed relative to the cosmic microwave background is 6,499 ± 18 km/s, which corresponds to a Hubble distance of 95.9 ± 6.7 Mpc (∼313 million ly).[2] NGC 5416 was discovered by German-British astronomer William Herschel in 1784.
The luminosity class of NGC 5416 is III-IV and it has a broad HI line.[2] According to the SIMBAD database, NGC 5416 is a radio galaxy.[1]
To date, 25 non-redshift measurements yield a distance of 80.152 ± 12.462 Mpc (∼261 million ly),[3] which is within the Hubble distance values. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 5416 could be approximately 41, 8 kpc (∼136,000 ly) if we used the Hubble distance to calculate it.[4]
