- IC 342 may have undergone a recent burst of star formation activity and is close enough to have gravitationally influenced the evolution of the local group of galaxies and the Milky Way. IC 342最近可能经历一次爆发性的恒星形成活动，它离本星系群和我们的银河系足够近，因此星系的演化受到了本地星系群和银河系重力的影响。
- M33, also known as the Triangulum Galaxy, is a member ofwhat's known as our Local Group of galaxies. M33俗称三角星系，是我们本星系群的重要一员。
- A prominent member of the local group of galaxies, M33 is also known as the Triangulum Galaxy and lies about 3 million light-years distant. 作为本星系内重要的一员，M33也被命为著名的三角星系，大约距离我们300万光年。
- M33 is part of what's known as the Local Group of galaxies, and it is gravitationally bound to our home galaxy the Milky Way. M33是已知的本星系群的一部分，而且，其因重力作用而被我们人类所在的银河系所束缚而牵制。
