Upsilon Andromedae d (υ Andromedae d, abbreviated Upsilon And d, υ And d), also named Majriti, is a super-Jupiter exoplanet orbiting within the habitable zone of the Sun-like star Upsilon Andromedae A, approximately 44 light-years (13.5 parsecs, or nearly 4.163×1014 km) away from Earth in the constellation of Andromeda. Its discovery made it the first multiplanetary system to be discovered around a main sequence star, and the first such system known in a multiple star system. The exoplanet was found by using the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.

In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars.[8] The process involved public nomination and voting for the new names. In December 2015, the IAU announced the winning name was Majriti for this planet.[10] The winning name was submitted by the Vega Astronomy Club of Morocco, honoring the 10th century scientist Maslama al-Majriti.
