HD 4166's Alternative Names

The Id of the star in the Henry Draper catalogue is HD4166.

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

Location of HD 4166

The location of the main sequence 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 4166, the location is 00h 44m 03.7639 and -05` 54° 03.726 .

Proper Motion of HD 4166

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 -0.74 milliarcseconds/year towards the north and 36.36 milliarcseconds/year east if we saw them in the horizon. . 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.

Physical Properties of HD 4166

HD 4166 Temperature and Colour

Based on the star's spectral type of A9V , HD 4166's colour and type is blue - white main sequence star. Based on the star's spectral, the stars temperature is between 7,500.00 and 10,000.00 degrees kelvin.

Distance to HD 4166

The Parallax of the star is given as 2.41000 which gives a calculated distance to HD 4166 of 1353.37 light years from the Earth or 414.94 parsecs. It is about 7,955,955,221,305,502 miles from Earth.

The star is roughly 85,586,922.33 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.

Travel Time to HD 4166

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.
