HD 79498

HD 79498 is a double star in the northern constellation of Cancer. The primary component of this pair has an orbiting exoplanet companion. This star is too faint to be viewed with the naked eye, having an apparent visual magnitude of 8.05. The system is located at a distance of 159 light years based on parallax measurements, and is drifting further away with a heliocentric radial velocity of 20 km/s. It has a relatively high proper motion, traversing the celestial sphere at an angular rate of $19.94$·yr−1.

The primary, designated component A, is a G-type main-sequence star with a stellar classification of G5 V. It has 8% greater mass compared to the Sun and a 5% larger girth. The star is estimated to be 2.8 billion years old and appears to be spinning slowly with a projected rotational velocity of 2.0 km/s. It has a higher than solar abundance of elements other than hydrogen and helium; what astronomers term a metal-rich star. The star is radiating 7% more luminosity than the Sun from its photosphere at an effective temperature of 5,800 K. There appears to be only a low level of magnetic activity in the star's chromosphere.

The secondary member, component B, is located at a projected separation of $0.2 arcsecond$ from the primary. It is a small red dwarf of spectral class M0 V.

Planetary system
The McDonald Observatory planet search program discovered an exoplanet orbiting the primary in 2011 using the radial velocity method.
