110 G. Aql is an orange to red less luminous star that can be located in the constellation of Aquila. HIP99024 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD190664. The Id of the star in the Gould Star Catalogue is 110. Stars in the southern hemisphere are more likely to have a Gould Id than the northern hemisphere. For example, there are no Gould classified stars in Ursa Major.
The location of the star in the galaxy is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is from celestial equator. The Declination is how up or down compared to the celestial equator and is expressed in degrees. For 110 G. Aql, the location is 20h 06m 12.19 and -04 d 04`41.2 .
All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving -035.00 ± 000.00 towards the north and 050.00 ± 001.00 east if we saw them in the horizon.
110 G. Aql has a spectral type of K0. This means the star is an orange to red coloured less luminous star. The star has a B-V Colour Index of 1.15 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 4,663 Kelvin.
110 G. Aql has been calculated as 7.27 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 5,058,742.43.km.
110 G. Aql has an apparent magnitude of 6.47 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of 1.47 If you used the 2007 Parallax value, you would get an absolute magnitude of 1.24. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 10.00 which gave the calculated distance to 110 G. Aql as 326.16 light years away from us or 100 parsecs. In 2007, Hipparcos data was revised with a new parallax of 9.00 which put 110 G. Aql at a distance of 362.40 light years or 111.11 parsecs.
The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Stellar Age, Metallicity or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
