Messier 35, and NGC 2158, two open clusters located in Gemini the Twins. These are more like distant relatives. M 35 is relatively near by at only 2,800 light years, and NGC 2158 is a distant 15,000 light years away. M 35 is a young cluster at around 150 million years old, and NGC 2158 is an old 2 billion years old cluster. M 35 has an abundance of bright blueish stars that burn through their fuel at a faster rate, and only the older more yellowish survive in NGC 2158.
