Definition: In this task, you are given a context, a subject, a relation, and many options. Based on the context, from the options select the object entity that has the given relation with the subject. Answer with text (not indexes).
Input: Context: A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek "", literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few billion stars to giants with one hundred trillion stars, each orbiting its galaxy's center of mass. Galaxies are categorized according to their visual morphology as elliptical, spiral and irregular. Many galaxies are thought to have black holes at their active centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of March 2016, GN-z11 is the oldest and most distant observed galaxy with a comoving distance of 32 billion light-years from Earth, and observed as it existed just 400 million years after the Big Bang., HD 40979 is a yellow-white dwarf star about 108 light-years away in the constellation of Auriga. The star is a member of a multiple system: it has a companion HD 40979B which shares its proper motion and is located at a projected distance of 6400 AU from the primary. HD 40979B itself has a companion (designated HD 40979C) at a projected distance of 129 AU from star B, making the system a triple., A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes., HD 40979 b is an extrasolar planet orbiting the star HD 40979 , was detected from the Lick and Keck observatories and photometric observations at Fairborn Observatory reveal low - amplitude brightness variations in HD 40979 . It is thought to be a large gas giant planet . It was discovered in 2002 by Debra Fischer ., Subject: hd 40979 b, Relation: constellation, Options: (A) auriga (B) sagittarius
Output:
auriga
