HD 192263 is an 8th magnitude star about 64 light years away [2] in the constellation of Aquila. The spectral type of the star is K2V, meaning that it is an orange dwarf, a type of star somewhat cooler and less luminous than the Sun. It is not visible to the unaided eye, but with good binoculars or small telescope it should be easy to spot.

Contents

The star HD 192263 is named Phoenicia. The name was selected in the NameExoWorlds campaign by Lebanon, during the 100th anniversary of the IAU. Phoenicia was an ancient thalassocratic civilisation of the Mediterranean that originated from the area of modern-day Lebanon. [8] [9]

Various companions for the star have been reported, but all of them are probably line-of-sight optical components or just spurious observations.

The apparent direction of the star lies close to the Earth's Celestial equator, and it rotates almost edge-on to Earth's line of sight. [10]

In 1999 an extrasolar planet was announced orbiting the star.

Planetary system

On 28 September 1999, a planet around HD 192263 was found by the Geneva Extrasolar Planet Search team using the CORALIE spectrograph on the 1.2m Euler Swiss Telescope at La Silla Observatory, [11] discovered independently by Vogt et al. [12]

HD 129445 is a G-type star found in the Circinus constellation located 219 light-years away from the Sun based on parallax. It is invisible to the naked eye with an apparent visual magnitude of 8.80. The star was observed by the Magellan Planet Search Program due to its absolute visual magnitude and high metallicity. The Magellan program conducted 17 doppler velocity measurements, which spans a full orbital period. The results led the program to detect a planet dubbed HD 129445 b. In 2023, the inclination and true mass of HD 129445 b were determined via astrometry.

HD 106515 is a binary star in the constellation of Virgo.
