The Leo Triplett (M66 group)

[m65-66mw.jpg] This small group of galaxies consists of the Messier objects M65 (NGC 3623) and M66 (NGC 3627) as well as the edge-on spiral NGC 3628. Lying at a distance of some 35 million light years, it is probably physically related to the M96 group.

The slightly more distant S0 or "early" Sa galaxy NGC 3593 is probably another member of the group, not in out image.

Our image was obtained by the German amateur Michael Weiland of the Interessengemeinschaft Astronomie at the University of Constance.

    The table below lists some data for the M66 group members:

    Name RA(h:m) Dec(d:m)type m_v dim RV
    NGC 3593 11:14.6 +12:49 Sb 11.0 5.8x2.5 510
    M65 11:18.9 +13:05 Sb/Sa 9.34 10.0x3.3 692
    M66 11:20.2 +12:59 Sb+ 9.04 8.7x4.4 623
    NGC 3628 11:20.3 +13:36 Sb 9.51 14.8x3.6 734

    Key: Name: Some catalog number or name; RA/Dec: Position 2000.0; type: Hubble type; m_v: apparent visual magnitude; dim: dimension in arc minutes; RV: radial velocity (all data from the Sky Catalog 2000 when available).
