There are officially 88 recognised star constellations, and the constellation your star is located in will dictate what time of the year it will be overhead and therefore visible from the UK. For this reason and to guarantee viability from the UK, we only allow a purchase from a constellation that resides in the northern hemisphere. If you would like to coincide the visibility of your star with an important date, such as a birthday or wedding anniversary we suggest you upgrade to select a constellation yourself such as Virgo, Aries and Leo.
