HD 114975 Star Facts (Distance, Colour, Radius & more)

HD 114975 is a Variable Star that is located in the constellation of Canes Venatici. Based on the spectral type (M0) of the star, the HD 114975 colour is red . It is not part of the Canes Venatici 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.

HD 114975 is located in the Milky Way galaxy, this is the galaxy that you reside in. In case you're wondering, HD 114975 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 HD 114975 and we have no probes on a rendezvous with the star.

HD 114975 radius is 57.26 times bigger than the Sun.

Using the most recent figures given by the 2007 Hipparcos data, HD 114975 distance from Earth is 1672.63 light years. When you look at HD 114975, 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.

HD 114975 Location

The location of the variable 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 HD 114975, the location is 13h 13m 35.94 and +36° 53` 15.3 .

HD 114975 Radial Velocity and Proper Motion

HD 114975 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 0.54 ± 0.22 milliarcseconds/year towards the north and 2.89 ± 0.38 milliarcseconds/year east if we saw them in the horizon.

HD 114975 Radial Velocity

The Radial Velocity, that is the speed at which the star is moving away the Sun is 0.32000 km/s with an error of about 0.19 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.

HD 114975 Physical Properties

HD 114975 Colour

Based on the star's spectral type of M0 , HD 114975's colour and type is red variable 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.

HD 114975 Effective Temperature

The star's effective temperature is 3,980 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin.

HD 114975 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 741.551 comes from the Vizier online catalogue. The star generates more energy than our star.

HD 114975 Radius

HD 114975 Radius has been calculated as being 57.26 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 39,841,508.km. If you need the diameter of the star, you just need to multiple the radius by 2.

HD 114975 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.

HD 114975 apparent magnitude is 6.5, 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, HD 114975 absolute magnitude is -1.58 If you used the 2007 Parallax value, HD 114975 absolute magnitude is -2.05.

Visible from Earth

HD 114975 is visible from Earth. The lower the Apparent Magnitude of a star or other object is, the easier it is to see in the night sky. An object with a magnitude greater than 6.5 can not be seen without the aid of a telescope or other device.

HD 114975 Distance from Earth

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 2.42000 which means HD 114975 distance from Earth is 1347.78 light years away from Earth or 413.22 parsecs. If you want that in miles, it is about 7,923,093,705,469,405.886, based on 1 Ly = 5,878,625,373,183.61 miles.

In 2007, Hipparcos data was revised with a new parallax of 1.95000 which puts HD 114975 distance from Earth as 1672.63 light years or 512.82 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 105,775,980.882 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. The star's Galacto-Centric Distance is 7,431 Parsecs or 24,237.198 Light Years. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*.

Alternative Names and Meanings

• HIP64530 is the reference name for the star in the Hipparcos Star Catalogue.
• The Id of the star in the Henry Draper catalogue is HD114975. 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-2541-220-1. 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+37 2383.

HD 114975 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.
