HD 187923

HD 187923 is a suspected variable star in the equatorial constellation of Aquila. It is a dim star that is just visible to the naked eye, having an apparent visual magnitude of 6.148. Based upon an annual parallax shift of, it is located 88 light years away. The star is moving closer to the Earth with a heliocentric radial velocity of −20.7 km/s. It has a relatively high proper motion, traversing the celestial sphere at the rate of per year.
This is an ordinary G-type main-sequence star with a stellar classification of G0 V. It has some similarities to the Sun, and thus is considered a solar analog. Brewer et al. estimate the star has 1.3 times the mass of the Sun and 1.44 times the Sun's radius. It is thought to be around 9 billion years old and is spinning slowly with a projected rotational velocity of 0.1 km/s. The star is radiating double the Sun's luminosity from its photosphere at an effective temperature of 5,774 K. Casagrande et al. gave a much lower mass estimate of 1.02 times the Sun's mass with an age of around 10.2 billion years.
