Project Gemini (IPA: / ˈ dʒ ɛ m ɪ n i /) was the second United States human spaceflight program to fly. Conducted after the first American crewed space program, Project Mercury, while the Apollo program was still in early development, Gemini was conceived in 1961 and concluded in 1966.
Geminga underwent a minor glitch in the late part of 1996, with a fractional change in frequency of 6.2 × 10 −10. [17]A 1998 study of the pre-glitch ephemeris suggested that the timings were being affected by reflex motion due to the presence of a low-mass planet in a 5.1-year orbit; [18] however, this was later shown to be an artifact of noise that affects the pulse times from Geminga ...
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
Pollux b, formally named Thestias / ˈ θ ɛ s t i ə s /, is an exoplanet candidate orbiting the star Pollux approximately 34 light-years away in the constellation of Gemini (the Twins). It is also designated β Geminorum b ( Latinized to Beta Geminorum b, abbreviated β Gem b) or HD 62509 b.
Gemini 11 (officially Gemini XI) [2] was the ninth crewed spaceflight mission of NASA's Project Gemini, which flew from September 12 to 15, 1966.It was the 17th crewed American flight and the 25th spaceflight to that time (includes X-15 flights over 100 kilometers (62 mi; 54 nmi)).
Gemini 1 was the first mission in NASA's Gemini program. [2] An uncrewed test flight of the Gemini spacecraft, its main objectives were to test the structural integrity of the new spacecraft and modified Titan II launch vehicle. It was also the first test of the new tracking and communication systems for the Gemini program and provided training ...
The primary is a white star of magnitude 4.8 and the secondary is a yellow star of magnitude 7.8. [8] U Gem is a dwarf nova type cataclysmic variable discovered by J. R. Hind in 1855. [9] Mu Gem (Tejat) is the Bayer designation for a star in the northern constellation of Gemini. It has the traditional name Tejat Posterior, which means back foot ...
