HIP 61051 Star Facts (Distance, Colour, Radius & more)
Contents
HIP 61051Star is located in the constellation of Virgo. Based on the spectral type (K0) of the star, the HIP 61051 colour is orange to red . It is not part of the Virgo constellation outline but is within the borders of the constellation.
The star can not be seen by the naked eye, you need a telescope to see it.
HIP 61051 is located in the Milky Way galaxy, this is the galaxy that you reside in. In case you're wondering, HIP 61051 is not located within the Solar System, there is only one star in the Solar System and that is the Sun.
There are no Exoplanets recorded on the site for the star and is most likely the case. If an exoplanet had been spotted or confirmed, it will probably be recorded in Exoplanet EU database.
No one has visited HIP 61051 and we have no probes on a rendezvous with the star.
HIP 61051 radius is 4.65 times bigger than the Sun.
Using the most recent figures given by the 2007 Hipparcos data, HIP 61051 distance from Earth is 597.37 light years. When you look at HIP 61051, you are in fact looking back in time, you are seeing how it looks years ago. Roughly, change the distance from light years to years, that will tell you how long ago we are looking at the star.
HIP 61051 Location
The location of the star in the night sky 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 object is compared to the celestial equator and is expressed in degrees. For HIP 61051, the location is 12h 30m 48.95 and +12° 29` 12.3 .
HIP 61051 Radial Velocity and Proper Motion
HIP 61051 Proper Motion
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 -5.67 ± 0.65 milliarcseconds/year towards the north and -28.15 ± 1.15 milliarcseconds/year east if we saw them in the horizon.
HIP 61051 Radial Velocity
The Radial Velocity, that is the speed at which the star is towards the Sun is -15.50000 km/s with an error of about 0.60 km/s . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.
HIP 61051 Physical Properties
HIP 61051 Colour
Based on the star's spectral type of K0 , HIP 61051's colour and type is orange to red star.
There is no relationship between colour and size, a red star can be both the largest and the smallest stars in the Universe. Small stars are more energy efficient than larger stars and live longer.
HIP 61051 Effective Temperature
The star's effective temperature is 5,059 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin.
HIP 61051 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. Our star, the Sun's value is 1. ' The figure of 12.756 comes from the Vizier online catalogue. The star generates more energy than our star.
HIP 61051 Radius
HIP 61051 Radius has been calculated as being 4.65 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 3,235,470.km. If you need the diameter of the star, you just need to multiple the radius by 2.
HIP 61051 Iron Abundance
HIP 61051 Iron Abundance is -0.097 with an error value of 0.02 Fe/H with the Sun has a value of 1 to put it into context. The value comes from the Hipparcos Extended Catalog.
HIP 61051 Surface Gravity
The Surface Gravity of the star as measured in CGS (Centimeter-Gram-Second) is 3.295. The gravity has a relationship to its mass and radius. The larger the mass, the larger the gravity. The star's surface gravity has an uncertainty range of between - and +.
HIP 61051 Apparent (Brightness) and Absolute Magnitudes
Absolute Magnitude is the apparent magnitude of the star from a distance of 10 parsecs or 32.6 light years. This assumes that there is nothing in between the object and the viewer such as dust clouds. To really compare the brightness of the star, it is best to use Absolute rather than Apparent Magnitude.
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.
HIP 61051 apparent magnitude is 8.65, this is a measure of the brightness of the star as seen from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, HIP 61051 absolute magnitude is 2.00 If you used the 2007 Parallax value, HIP 61051 absolute magnitude is 2.34.
Visible from Earth
HIP 61051 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.
HIP 61051 Distance from Earth
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 4.67000 which means HIP 61051 distance from Earth is 698.42 light years away from Earth or 214.13 parsecs. If you want that in miles, it is about 4,105,749,533,138,896.896, based on 1 Ly = 5,878,625,373,183.61 miles.
In 2007, Hipparcos data was revised with a new parallax of 5.46000 which puts HIP 61051 distance from Earth as 597.37 light years or 183.15 parsecs. It should not be taken as though the star is moving closer or further away from Earth. It is purely that the distance was recalculated.
Using the 2007 distance, the star is roughly 37,777,136.029 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.
Alternative Names and Meanings
- HIP61051 is the reference name for the star in the Hipparcos Star Catalogue.
- The Id of the star in the Henry Draper catalogue is HD108915. The catalogue was started by the American doctor and has been expanded on over the years.
- The star is catalogued in the Tycho-2 star catalogue as TYC-877-335-1. The catalogue lists 2 millions stars and its homepage is E.S.A.
- BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD+13 2545.
HIP 61051 Travel Time
The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).
The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2.

Comparison Between HIP 61051 and The Sun
Below is a tabular view of the star facts with the values of the Sun on the right so you can compare against our own star, the Sun. The Sun is our nearest star and it is what keeps us warm and gives us light as we complete one orbit in 365.24 days.
If you want to see the comparison between HIP 61051 and our star, the Sun, you will need a screen of at least 800px across. Rotating your screen maybe sufficient to see the Stellar values for comparison.
