Bosona, also HD 206610, is an orange giant star in the constellation of Aquarius. It is a K-type giant star with an apparent magnitude of 6.249, which, according to the Bortle scale, makes it faintly visible to the naked eye from dark rural skies. This star is spinning slowly with a projected rotational velocity of 1.77 km/s. [5] [6] [7] [2]

Naming

The star HD 206610 and its planet HD 206610 b are named Bosona and Naron respectively. The names were selected in the NameExoWorlds campaigns by Bosnia and Herzegovina during the 100th anniversary of the IAU. 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]

The host star HD 206610 is named Bosona in accordance with the historic name for Bosnia, Horion Bosona, described in De Administrando Imperio by Porphyrogenitus in 10rth century, and its namesake the river Bosna's ancient name Bosona (Bosina, Basina, Basante). [8] [9] [10]

Planetary system

HD 206610 has one known planet, HD 206610 b named Naron, discovered in 2010 using the radial velocity method. [11]

HD 93083 is an orange-hued star in the southern constellation of Antlia. It has the proper name Macondo, after the mythical village of the novel One Hundred Years of Solitude. The name was selected by Colombia during the IAU's NameExoWorlds campaign. The star has an apparent visual magnitude of 8.30, which is too faint to be visible to the naked eye. It is located at a distance of 93 light years from the Sun based on parallax. HD 93083 is drifting further away with a radial velocity of +43.65 km/s, having come to within 43 light-years some 484,000 years ago.

HD 4208 is a star in the southern constellation of Sculptor. It has a yellow hue with an apparent visual magnitude of 7.78, making it too dim to be visible to the naked eye. But with binoculars or small telescope it should be an easy target. This object is located at a distance of 111.6 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +57 km/s.

HD 45350 is a solar analog star with an exoplanetary companion in the northern constellation of Auriga. It has an apparent visual magnitude of 7.89, which means it is an 8th magnitude star that is too dim to be readily visible to the naked eye. The system is located at a distance of 153 light-years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −21 km/s.

HD 175541 is an 8th magnitude star with an exoplanetary companion in the constellation Serpens. It has the proper name Kaveh, which was selected by Iran during the NameExoWorlds campaign as part of the 100th anniversary of the IAU. Kaveh is one of the heroes of Shahnameh. The apparent visual magnitude of 8.02 is too faint for this star to be visible in the naked eye. It is located at a distance of approximately 424 light years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of +20 km/s. Despite its distance, it was given the number 736 in the Gliese Catalogue of Nearby Stars.

With an apparent visual magnitude of 8.97, it is too dim to be viewed with the naked eye, but can be seen with powerful binoculars or a small telescope. Parallax measurements provide a distance estimate of approximately 356 light years from the Sun, but it is drifting closer with a radial velocity of −63 km/s. It is predicted to come as close as 189.5 light-years in 1.345 million years.
