NGC_2243 is an open star cluster located in the constellation Monoceros, which is also known as the Unicorn. It was discovered by the astronomer John Herschel in 1834. This cluster is approximately 2,000 light-years away from Earth and contains several hundred stars that are loosely bound by gravity. The age of NGC_2243 is estimated to be around 100 million years, making it relatively young in astronomical terms. The cluster is notable for its bright stars and is often studied to understand the formation and evolution of star clusters in our galaxy, the Milky Way.
