HD 206610, also known as Bosona, is a

apparent visual magnitude of 8.34.[1] The system is drifting closer with a radial velocity of −18.6 km/s.[2]

This is an aging

projected rotational velocity of 1.77 km/s.[6] The star is radiating 18[5] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,819 K.[6]

The star HD 206610 and its exoplanet HD 206610 b are named Bosona and

Porphyrogenitus in 10th century, and its namesake the river Bosna's ancient name Bosona (Bosina, Basina, Basante). Naron is one of the names given to the Neretva river in Herzegovina originating with the Romans (Naro, Narona, Narenta, Nerenta), while in local tradition the name is said to go back even earlier with the Celts who called it Nera Etwa, which means the Flowing Divinity.[8][9][10]

Planetary system

HD 206610 has one known exoplanet,
