Visible to the unaided eye from dark sky areas, it was cataloged in 130 BC by Greek astronomer Hipparchus. Some 7,000 light-years away, this pair of open star clusters is also an easy binocular target, a striking starfield in the northern constellation of the mythical Greek hero Perseus. Now known as h and chi Persei, or NGC 869 (above right) and NGC 884, the clusters themselves are separated by only a few hundred light-years and contain stars much younger and hotter than the Sun. In addition to being physically close together, the clusters&#8217; ages based on their individual stars are similar &#8211; evidence that both clusters were likely a product of the same star-forming region. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap221122.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Few star clusters this close to each other.
