HD 175607, HIP93373

HD 175607 is a white to yellow main sequence dwarf star that can be located in the constellation of Pavo. The star can not be seen by the naked eye, you need a telescope to see it. It is calculated at being 10.320 Billion Years old. This information comes from ExoPlanet. HD 175607 has at least 1 Extrasolar Planets believed to be in orbit around the star.

HD 175607's Alternative Names

HIP93373 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD175607.

More details on star alternative names can be found at Star Names.

Location of HD 175607

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 along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the star is compared to the celestial equator and is expressed in degrees. For HD 175607, the location is 19h 01m 05.30 and -66° 11` 30.3 .

Proper Motion of HD 175607

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 -386.98 ± 0.62 miliarcseconds/year towards the north and 132.06 ± 1.01 miliarcseconds/year east if we saw them in the horizon. The Radial Velocity, that is the speed at which the star is moving away/towards us is -91.89000 km/s with an error of about 0.00 km/s .

HD 175607 Luminosity

Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The figure of 0.7100000 that I have given is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012.

Physical Properties (Colour, Temperature, Age, Mass) of HD 175607

HD 175607 has a spectral type of G8V. This means the star is a white to yellow main sequence dwarf star. The star is 7365.00000000 Parsecs from the Galactic Centre or terms of Light Years is 24021.9302856000000000s. The star has a B-V Colour Index of 0.69 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 5,594 Kelvin.

HD 175607 Radius has been calculated as being 0.86 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 596,885.02.km. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures. The star's solar mass is 0.71 times that of the Sun's. The Sun's Mass is 1,989,100,000,000,000,000,000 billion kg. which to calculate using this website is too large. To give idea of size, the Sun is 99.86% the mass of the solar system.

The star's metallicity is -0.620000, this value is the fractional amount of the star that is not Hydrogen (X) or Helium (Y). An older star would have a high metallicity whereas a new star would have a lower one.

The star is believed to be about 10.32 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.

HD 175607 Apparent and Absolute Magnitudes

HD 175607 has an apparent magnitude of 8.60 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 5.32 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.

Distance to HD 175607

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 22.09 which gave the calculated distance to HD 175607 as 147.65 light years away from Earth or 45.27 parsecs. It would take a spaceship travelling at the speed of light, 147.65 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star's Galacto-Centric Distance is 7,365.00 Parsecs or 24,021.93 Light Years. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*.

Source of Information

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 Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
