Question: The Making of the Representative for Planet 8 features an empire named after a star in what constellation?
Context: The Making of the Representative for Planet 8 (opera) HAT-P-8b is an extrasolar planet located approximately 750 light years away in the constellation of Pegasus, orbiting the 10th magnitude star GSC 02757-01152.  This planet was discovered by transit on December 5, 2008.  Despite the designation as HAT-P-8b, it is the 11th planet discovered by the HATNet Project.  The mass of the planet is 50% more than Jupiter while the radius is also 50% more than Jupiter.  The mass of this planet is exact since the inclination of the orbit is known, typical for transiting planets.  This is a so-called “hot Jupiter” because this Jupiter-like gas giant planet orbits in a really close torch orbit around the star, making this planet extremely hot (in the order of a thousand kelvins).  The distance from the star is roughly 20 times smaller than that of Earth from the Sun, which places the planet roughly 8 times closer to its star than Mercury is from the Sun.  The “year” on this planet lasts only 3 days, 1 hour, 49 minutes, and 54 seconds, compared with Earth's 365 days, 6 hours, 9 minutes, and 10 seconds in a sidereal year. The Making of the Representative for Planet 8 is a 1982 science fiction novel by Doris Lessing.  It is the fourth book in her five-book "Canopus in Argos" series and relates the fate of a planet, under the care of the benevolent galactic empire Canopus, that is plunged into an ice age.  It was first published in the United States in January 1982 by Alfred A. Knopf, and in the United Kingdom in March 1982 by Jonathan Cape. HD 16417 b (also called λ Fornacis b) is an extrasolar planet located approximately 84 light years away in the constellation of Fornax, orbiting the 6th magnitude G-type main sequence star HD 16417.  This planet has minimum mass only 7% that of Jupiter, making this a Neptune-mass planet.  In addition to this, it orbits relatively close to the host star and suffers high temperature.  It is the third planet discovered in Fornax constellation on February 23, 2009.  This planet was discovered by a method called the radial velocity method. Canopus ( ), also designated Alpha Carinae (α Carinae, abbreviated Alpha Car, α Car), is the brightest star in the southern constellation of Carina, and the second-brightest star in the night-time sky, after Sirius.  Canopus's visual magnitude is −0.74, and it has an absolute magnitude of −5.71. Akhnaten is an opera in three acts based on the life and religious convictions of the pharaoh Akhenaten (Amenhotep IV), written by the American minimalist composer Philip Glass in 1983.  "Akhnaten" had its world premiere on March 24, 1984, at the Stuttgart State Theatre, under the German title "Echnaton".  Paul Esswood sang the title role, German director Achim Freyer staged the opera in an abstract style with highly ritualistic movements.  The American premiere was held on October 12, 1984, at the Houston Grand Opera, where Glass's opera "The Making of the Representative for Planet 8" also premiered. HD 7924 b is an extrasolar planet located approximately 54 light years away in the constellation of Cassiopeia, orbiting the 7th magnitude K-type main sequence (slightly metal poor) star HD 7924.  It was published on January 28, 2009 and is the second planet discovered in the constellation Cassiopeia.  (The first planet discovered in this constellation is HD 17156 b, which was published on April 14, 2007). HD 156668 b is an extrasolar planet orbiting the star HD 156668 78.5 light-years away in the constellation Hercules.  It has a minimum mass of 3.1 Earth masses.  At the time of discovery it was the second least massive planet discovered by the radial velocity method, subject to the mass/inclination degeneracy that affects radial velocity measurements.  The only radial velocity planet less massive than this planet is Gliese 581 e, which was discovered on April 21, 2009, and has a minimum mass of 1.94 Earth masses.  In addition to this, it has the lowest semi-amplitude, or the speed of the stellar wobble caused by planet's gravity tugging on the star determined by radial velocity, at 2.2 m/s.  This planet was discovered on January 6, 2010; it is the 8th planet discovered in 2010 after the first five planets detected by Kepler on January 4 and two planets around HD 9446 on January 5. Kepler-1520 (initially published as KIC 12557548) is a K-type main-sequence star located in the constellation Cygnus.  The star is particularly important, as measurements taken by the "Kepler" spacecraft indicate that the variations in the star's light curve cover a range from about 0.2% to 1.3% of the star's light being blocked.  This indicates that there may be a rapidly disintegrating planet, a prediction not yet conclusively confirmed, in orbit around the star, losing mass at a rate of 1 Earth mass every billion years.  The planet itself is about 0.1 Earth masses, or just twice the mass of Mercury, and is expected to disintegrate in about 100-200 million years.  The planet orbits its star in just 15.7 hours, at a distance only two stellar diameters away from the star's surface, and has an estimated effective temperature of about 2255 K.  The orbital period of the planet is one of the shortest ever detected in the history of the extrasolar planet search.  In 2016, the planet was confirmed as part of a data release by the "Kepler" spacecraft. HD 104067 b is an extrasolar planet which orbits the K-type main sequence star HD 104067, located approximately 68 light years away in the constellation Corvus.  This planet has at least one-sixth the mass of Jupiter and takes over one-sevenths of a year to orbit the star at a semimajor axis of 0.26 AU.  This planet was detected by HARPS on October 19, 2009, together with 29 other planets.  It is also the first planet to be discovered in this constellation.
