Information:  - HD 210277 b is an extrasolar planet orbiting the star HD 210277 . It was discovered in September 1998 by the California and Carnegie Planet Search team using the highly successful radial velocity method . The planet is at least 24 % more massive than Jupiter . The mean distance of the planet from the star is slightly more than Earth 's distance from the Sun. However , the orbit is very eccentric , so at periastron this distance is almost halved , and at apastron it is as distant as Mars is from the Sun. In 2000 , a group of scientists proposed , based on preliminary data from the Hipparcos astrometrical satellite , that the planet would have an inclination of 175.8 ° and a true mass of 18 times Jupiter making it a brown dwarf instead of a planet . However these measurements were later proved useful only for upper limits of inclination . If the planet orbits in the same plane as the claimed circumstellar disk , which seems a plausible assumption , it would have an inclination of 40 ° and an absolute mass of 2.2 times Jupiter , however later observations failed to confirm the disk 's existence .  - Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.  - An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Although Meteor Crater is perhaps the best-known example of a small impact crater on Earth, impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins.  - HD 210277 is a 7th magnitude star in the constellation of Aquarius. It is a yellow dwarf star (spectral type G0V) with a mass around 0.92 times that of our Sun. Since its distance is about 70 light years, it is not visible to the unaided eye. With binoculars it is easily visible.    Given the information above, choose from the list below the object entity that exhibits the relation 'constellation' with the subject 'hd 210277 b'.  Choices: - aquarius  - crater
