Facts
HIP 61597star is located in the constellation of Camelopardalis, The Giraffe . It is not part of the Camelopardalis constellation outline but is within the borders of the constellation.
Based on the spectral type (G0), HIP 61597 colour is yellow, a mid-ranged temperature star. Our star is actually white, its just the atmosphere that makes it look yellow.
HIP 61597 temperature is in the range of between 5,200 and 6,000 Kelvin. Based on the spectral type (G0) as we don't have the exact temperature', we can deduce that the surface temperature of HIP 61597 is in the order of 5,000 and 6,000K based on the notes from Harvard University. To put this in context, the temperature of our Sun is about 5,778 Kelvin as said by Google.
Based on a parallax of 28.26, HIP 61597 distance from Earth can be calculated at being 115.42 light years away or 35.79 parsecs.
HIP 61597 cannot be seen by the naked eye, you will need a telescope to observe it.
Location
The location of the HIP 61597 in the night sky is determined by the right ascension (R.A.) and declination (Dec.). These are equivalent to the Longitude and Latitude on Earth. The Right Ascension (Longitude) is expressed in time (hh:mm:ss) and is how far the star is along Earth's celestial equator. If the R.A. is positive, then it's eastwards and vice versa.
The Declination (Latitude) is how far north or south the object is compared to the celestial equator and is expressed in degrees. If the value is positive, it is north of the celestial equator. For HIP 61597, the location is 12h 37m 19.62 and +79° 12` 55.6 .
Based on the location of Camelopardalis, HIP 61597 can be located in the northern hemisphere of the celestial sky. The celestial hemisphere is equivalent to the hemispheres on Earth. HIP 61597 is north of the Ecliptic. The Ecliptic is the path that the Earth takes as it orbits the Sun. As the Earth is titled, we therefore have Celestial and Ecliptic hemispheres and they can be different for a star.
Physical Properties
Spectral Type
HIP 61597 spectral type of G0 which means its colour and type is yellow star. There is no relationship between colour and size. For example, a red star can be large or small. Small stars are more energy efficient than larger stars and live longer.
HIP 61597 Luminosity
Luminosity is the amount of energy a star pumps out relative to the amount that our star, the Sun, gives out. Our star, the Sun's value is 1. HIP 61597 luminosity figure of 1.83 is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012. The star generates more energy than our star.
Iron Abundance
HIP 61597 Iron Abundance is 0.32 with an error value of 0.02 Fe/H, with the Sun having a value of 1 to put it into context. The value comes from the Hipparcos Extended Catalog.
HIP 61597 Age
HIP 61597 age according to Hipparcos data files put the star at an age of about 2.6 billion years old but could be between 1.3 and 4.2 billion years old. In comparison, the Sun's age is about 4.6 billion years old. The smaller star is, the more efficient it is with its fuel and so will live longer than a star which is very large. HIP 61597 lifespan could be around 10 billion years. This is assuming the star is a typical yellow star (G Type).
Magnitude (Apparent / Absolute / Visible)
A number represents a star’s magnitude, whether apparent/visual or absolute. The smaller the number, the brighter the star is. The Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
HIP 61597 apparent magnitude is 6.99, which is a measure of the star's brightness as seen from Earth. Apparent Magnitude is also known as Visual Magnitude.
If you use the 1997 parallax value, HIP 61597' absolute magnitude is 4.22. If you use the 2007 parallax value, HIP 61597' absolute magnitude is 4.25. Absolute Magnitude is the star's apparent magnitude from 10 parsecs or 32.6 light years. The magnitude assumes nothing is between the object and the viewer, such as dust clouds. To compare different stars' actual brightness, you would best use Absolute rather than Apparent Magnitude.
HIP 61597 cannot be seen from the Earth with the naked eye, it is just too far and too dim to be seen. Only objects with a magnitude of 6.5 or less can be seen on a clear night.
Radial Velocity and Proper Motion
In simplistic terms, all non-rogue stars, like planets, orbit around a central object, although that is actually not true. Where is the centre of the Solar System. For simplicity it's the central star, such as the Sun. In the case of a star, it's the galactic centre. The constellations 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 is measured in milliarcseconds. HIP 61597 is moving 15.38 ± 0.37 milliarcseconds/year towards the north and -141.18 ± 0.44 milliarcseconds/year east if we saw them in the horizon.
The radial velocity, the speed at which the HIP 61597 is towards the Sun, is -18.38000 km/s with an error of about 0.09 km/s . When the value is negative, the star and the Sun are getting closer to one another; likewise, a positive number means that two stars are moving away. It's nothing to fear as the stars are so far apart they won't collide in our lifetime, if ever.
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 an E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated, so they could be wrong. Information regarding Metallicity and/or Mass is from the E.U. Exoplanets. The data was obtained as of 12th Feb 2017.
