NGC 2104 is a bright open star cluster located in the constellation of Lynx. It was discovered by the astronomer William Herschel in 1788 and is approximately 4,000 light-years away from Earth. The cluster contains several young, hot stars that are primarily blue in color, indicating their high temperatures. This star cluster is part of a larger region of space that is rich in stellar formation. NGC 2104 is notable for its relatively high concentration of stars, making it an interesting object for astronomers studying the formation and evolution of star clusters in our galaxy, the Milky Way.
