Dilhan Eryurt (29 November 1926 – 13 September 2012) was a Turkish astrophysicist who made major contributions to scientific research on the formation and evolution of the Sun and other main sequence stars.

[2] Her father was Abidin Ege [tr], who was a member of the Grand National Assembly of Turkey for Denizli Province in 1944.

[citation needed] After graduating from Istanbul University in 1946, Eryurt worked as an honorary assistant for two years for Tevfik Oktay Kabakçıoğlu.

[citation needed] The studies were important at that time to influence the course of scientific and engineering research aims of new space flights.

She was awarded the Apollo Achievement Award[4] in 1969 for her successful work contributing to the achievement of the Apollo 11 mission's first landing on the Moon and subsequent lunar exploration, by providing NASA engineers with crucial information for modelling solar impact on the lunar environment.

The institute sent her to the University of California to work on a research study about the formation and development of main sequence stars.

[7] Eryurt was honoured with a Google Doodle on 20 July 2020 in commemoration of the 51st anniversary of the first manned landing on the Moon by Neil Armstrong and Buzz Aldrin as part of the Apollo 11 mission.
