HD 333333's Alternative Names

The Id of the star in the Henry Draper catalogue is HD333333.

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

Location of HD 333333

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 HD 333333, the location is 20h 00m 34.9978 and +27° 54` 40.794 .

Proper Motion of HD 333333

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 -15.97 milliarcseconds/year towards the north and -3.00 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.

HD 333333 Colour and Temperature

HD 333333 has a spectral type of A3 E. This means the star is a blue - white star.

Distance to HD 333333

The Parallax of the star is given as 1.97 which gives a calculated distance to HD 333333 of 1655.65 light years from the Earth or 507.61 parsecs. It is about 1,110,306,421,804 miles from Earth.

The star is roughly 104,701,348.73 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 333333

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.
