| dbo:abstract | 38 Geminorum is a binary star system in the northern zodiac constellation of Gemini. It has the Bayer designation e Geminorum, while 38 Geminorum is the Flamsteed designation. This system is visible to the naked eye as a faint, white-hued point of light with an apparent visual magnitude of 4.71. The primary component is a magnitude 4.75 star, while the secondary is magnitude 7.80. The system is located about 98 light years away from the Sun based on parallax, and is drifting further away with a radial velocity of +16 km/s. It is a potential member of the Tucana–Horologium stellar kinematic group. This is a wide binary system with a projected separation of 184.3 AU. Two sets of low quality orbital elements have been computed for this system, yielding periods of 1,943.8 years and 3,190 years, and eccentricities of 0.150 and 0.485, respectively. As of 2018, the pair had an angular separation of 7.4″ along a position angle of 143°. Abt and Morrell (1995) classified the primary component as an A-type main-sequence star with a stellar classification of A8V. It is a suspected chemically peculiar star of subtype CP1 (an Am star), which Slettebak (1955) classified as kA8mF0Vp. This notation indicates the star displays the calcium K line of an A8 star and the metal lines of an F0V star. In 1949, J. Hopmann catalogued it as a suspected Delta Scuti variable. The secondary is a G-type main-sequence star with a class of G6V. (en) 38 Geminorum (e Geminorum) é uma estrela na direção da Gemini.

(pt) 38 Geminorum, som är stjärnans Flamsteed-beteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Tvillingarna och har även Bayer-beteckningen e Geminorum. Den har en kombinerad skenbar magnitud på 4,71 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 33,9 mas, beräknas den befinna sig på ett avstånd på ca 96 ljusår (ca 30 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 16 km/s. Stjärnan är en potentiell medlem i rörelsegruppen Tucana – Horologium.
