Segue 2 is a dwarf spheroidal galaxy situated in the constellation Aries and discovered in 2009 in the data obtained by Sloan Digital Sky Survey. The galaxy is located at the distance of about 35 kiloparsecs (35,000 parsecs; 110,000 light-years) from the Sun and moves towards the Sun at a speed of 40 kilometres per second (25 mi/s).

2013年4月22日 · Segue 2, discovered by Belokurov et al. (2009), is a galaxy with a luminosity of only 900 L_sun. We present Keck/DEIMOS spectroscopy of 25 members of Segue 2--a threefold increase in spectroscopic...

Segue 2 is a Galaxy located in the constellation of Aries in the northern hemisphere. Segue 2 is not a Messier Object and doesn't have a Messier Number. The galaxy is separate and distinct, not in Milky Way galaxy or The Solar System. Nothing indicates Exoplanets with or without Alien life forms orbiting any of the many stars the galaxy has.

Abstract: We announce the discovery of a new Milky Way satellite Segue 2 found in the data of the Sloan Extension for Galactic Understanding and Exploration (SEGUE). We followed this up with deeper imaging and spectroscopy on the Multiple Mirror Telescope (MMT).

SEGUE-2. The Sloan Extension for Galactic Understanding and Exploration (SEGUE) focuses on the structure and evolution of our own Milky Way galaxy. The SEGUE-2 survey builds off of the work of SEGUE-1.

2022年4月1日 · SEGUE-2 targeted prioritized distant halo tracers (blue horizontal-branch stars, K giants, and M giants) and metal-poor or kinematically hot populations. The main goal of SEGUE-2 was to...

Segue 2, discovered by Belokurov et al. ( 2009), is a galaxy with a luminosity of only 900 L ☉ 900 subscript 𝐿 ☉ 900~ {}L_ {\sun}. We present Keck/DEIMOS spectroscopy of 25 members of Segue 2—a threefold increase in spectroscopic sample size. The velocity dispersion is too small to be measured with our data.

SEGUE is a magnitude-limited survey; the spectra on each plate are integrated to a target S/N at a fiducial magnitude. For each line of sight, SEGUE identifies spectroscopic targets using SDSS photometry and astrometry for fiber assignment (see SEGUE Target Selection). A number of fibers are also devoted to calibration.

2009年3月19日 · Using the existing SDSS spectrographs, SEGUE-2 will obtain spectra of 140,000 stars in selected high-latitude fields to a magnitude limit r ~ 19.5, more than doubling the sample of distant halo...
