Extrasolar planet. Artwork of a hypothetical extrasolar planet surface. The night sky shows that the planet orbits in a region of the Milky Way galaxy where there are many open star clusters. An open star cluster is a loose grouping of stars within a galaxy. The stars tend to be young and may number in the hundreds. Over time, due to the gravitational forces exerted by other stars in the galaxy, the stars of an open star cluster will drift apart.
