IC 342/Maffei Group facts for kids
Imagine looking up at the night sky. You might see stars, but did you know those stars are part of huge groups called galaxies? And galaxies often hang out together in even bigger groups! The IC 342/Maffei Group is one of these galaxy groups. It's special because it's the closest group of galaxies to our very own Local Group, which includes our Milky Way galaxy.
This group is mainly made up of two bright galaxies: IC 342 and Maffei 1. Most of the other galaxies in the group are found close to one of these two main galaxies. Both the IC 342/Maffei Group and our Local Group are part of an even larger structure called the Virgo Supercluster.

What is a Galaxy Group?
Galaxies and Their Homes
Galaxies are like huge islands in space. Each island is filled with billions of stars, gas, dust, and something mysterious called dark matter. Our own Sun is just one star in the Milky Way galaxy. Galaxies come in different shapes, like spirals, ovals, or irregular blobs.
Just like cities on Earth, galaxies don't usually float alone in the vastness of space. They tend to gather together. A "galaxy group" is a collection of about 50 or fewer galaxies that are held together by gravity. These groups are the smallest kinds of galaxy clusters.
Our Cosmic Neighborhood
Our Milky Way galaxy is part of a galaxy group called the Local Group. This group has about 80 galaxies. The two biggest galaxies in our Local Group are the Milky Way and the Andromeda Galaxy. The IC 342/Maffei Group is like our next-door neighbor in the universe. It's the closest galaxy group to our Local Group.

The Main Galaxies: IC 342 and Maffei 1
The IC 342/Maffei Group gets its name from its two most important members. These are the brightest and biggest galaxies in the group.
- IC 342: This is a beautiful spiral galaxy. It's sometimes called the "Hidden Galaxy." This is because it's located behind a lot of dust and gas in our own Milky Way galaxy. This dust makes it hard for us to see it clearly. Even though it's hard to see, it's one of the brightest spiral galaxies in our nearby universe.
- Maffei 1: This is a large elliptical galaxy. Like IC 342, it's also hidden behind the dust of the Milky Way. It was only discovered in 1968 by an Italian astronomer named Paolo Maffei. This galaxy is one of the closest giant elliptical galaxies to us.
Where in Space is It?
The IC 342/Maffei Group is located in the direction of several constellations. These include Cassiopeia, Camelopardalis, and Perseus. These constellations are visible in the northern sky.
Both the IC 342/Maffei Group and our Local Group are part of a much larger structure called the Virgo Supercluster. A supercluster is a huge collection of galaxy groups and galaxy clusters. It's one of the biggest known structures in the universe!
