c Puppis (HIP 37819)

c Puppis is an orange giant star in the constellation Puppis. At 1,085 light years away, it is the 335th brightest star in the Earth's sky, where it shines at an apparent visual magnitude of 3.62. It is moving through the Galaxy at a speed of 25.3 km/s relative to the Sun and is part of the NGC 2451B moving group. Its projected Galactic orbit carries it between 24,400 and 27,600 light years from the center of the Galaxy. It came closest to the Sun 8.6 million years ago when it had brightened to magnitude 2.99 from a distance of 811 light years.
