Object name: NGC4145
Designation(s): NGC4145, NGC4145A,
NGC 4145 is a barred spiral in western Canes Venatici about 68 million light-years distant. Redshift puts it a bit closer, other measurements at NED average 67 with the Spitzer Space Telescope website saying 68. It is considered part of the Ursa Major Galaxy group. While it is listed as having HII emission and a hint of it is seen in my image most say it has little dust and gas left so it's star-forming days are mostly over. It still has some blue in its arms, however. The Spitzer image is rather dim where star formation would normally be seen in IR indicating there really isn't much star formation going on. NGC 4145 was discovered by William Herschel on March 18, 1787. It is in the second H400 Observing Program.
