# HD 115004

HD 115004 is a single star in the northern constellation of Canes Venatici. It is faintly visible to the naked eye with an apparent visual magnitude of 4.94. Based upon an annual parallax shift of 7.10±0.24 mas, it is located around 460 light years from the Sun. The star is moving closer with a heliocentric radial velocity of −22 km/s. HD 115004 will make its closest approach in about 1.7 million years at a separation of around 390 ly (119.45 pc).

This is an evolved giant star, most likely (97% chance) on the horizontal branch, with a stellar classification of G8.5 III CN0.5. The suffix notation indicates a mild overabundance of the CN molecule in the stellar atmosphere. It has an estimated 3.2 times the mass of the Sun and, at the age of 440 million years, has expanded to 23 times the Sun's radius. The star is radiating around 242 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,761 K.
