Task: Question Answering
Input (English): Context: HD 88133 b is an extrasolar planet orbiting the star HD 88133 . It is probably less massive than Jupiter and even Saturn . It orbits the star in a very tight orbit , completing one revolution around the star in every three and half days or so . Despite the relatively large radius of the star ( about 2 times Solar ) , no transits have been detected ., 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., 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 88133 is an 8th magnitude star in the constellation of Leo. It is classified as a yellow subgiant star (spectral type G5IV). It is slightly more massive than our Sun, cooler and more luminous. As a subgiant, it has left the main sequence and started to evolve towards red gianthood. Located at a distance of 240 light years from Earth it is not in our immediate neighbourhood and thus not visible to the unaided eye. With a small telescope it should be easily visible., Subject: hd 88133 b, Relation: constellation, Options: (A) leo (B) sagittarius
Output (English): leo
