NGC 4102 is an Active Galactic Nuclei/Nucleus located in the constellation of Ursa Major in the northern hemisphere. NGC 4102's distance from Earth is 63,600,493.65 light years.

Spiral galaxy NGC 4102 is one of a group of galaxies in Ursa Major that is further away than the M-81/M-82 galaxy group. The red shift (Hubble Constant of 62 Km/sec per Mpc) gives a distance estimate of 44 million light years and a diameter of 40,000 light years.

2010年8月10日 · The composite galaxy NGC 4102 hosts a LINER nucleus and a starburst. We mapped NGC 4102 in the 12.8 micron line of [NeII], using the echelon spectrometer TEXES on the NASA IRTF, to obtain a data cube with 1.5" spatial and 25 km/s spectral, resolution.

2010年12月14日 · We have investigated the broad band X-ray spectrum of NGC 4102, one of the most luminous LINERs in the Swift/BAT survey. We studied a 80 ksec Suzaku spectrum of NGC 4102, together with archival Chandra and Swift/BAT observations.

2014年12月8日 · NASA has released a dazzling image from the Hubble Space Telescope, showing a nearby spiral galaxy called NGC 4102.

NGC 4102 is an intermediate barred spiral galaxy located in the northern constellation of Ursa Major. It is visible in a small telescope and has an apparent visual magnitude of 11.2.

NGC 4102 is a Intermediate Spiral Galaxy in the Ursa Major constellation. NGC 4102 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 11.8, NGC 4102 is visible with the help of a telescope having an aperture of 8 inches (200mm) or more.
