Gemini

Gemini is a name used for several distinct topics across astronomy, astrology, space exploration, and finance. The term is closely associated with the concept of twins or duality, which appears in both the constellation and the zodiac sign, as well as in the two-person crewed space program and the modern cryptocurrency exchange.

In astronomy, Gemini is a prominent northern constellation located near Orion. It contains the bright stars Castor and Pollux, which are traditionally identified with the twins. The constellation lies along the ecliptic in many cultures and includes several star-forming regions and deep-sky objects. In Greek mythology, Castor and Pollux are the twin brothers whose fates differ—one immortal, one mortal—yet who share a common celestial realm.

In astrology, Gemini is the zodiac sign for those born roughly between late May and late June. It is categorized as an air, mutable sign and is traditionally ruled by Mercury. People associated with Gemini are often described as communicative, adaptable, curious, and quick-witted, reflecting the sign’s emphasis on information exchange and versatility.

Gemini also refers to Project Gemini, the United States NASA spaceflight program conducted from 1961 to 1966. The program built on Mercury and aimed to develop and test spaceflight techniques needed for Apollo, including EVA (spacewalks), orbital rendezvous and docking, and longer-duration missions. Notable milestones include the first American spacewalk and the first successful orbital rendezvous between spacecraft.

Finally, Gemini is the name of a cryptocurrency exchange and custodian founded in 2014 by Cameron and Tyler Winklevoss. Regulated by the New York State Department of Financial Services, Gemini provides digital asset trading and custody services and has expanded into related financial products and services.
