DG Tauri

DG Tauri Facts

Location of DG Tauri

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 DG Tauri, the location is 04 27 04.6913654419 and +26 06 16.041555299 .

Radial Velocity and Proper Motion of DG Tauri

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 -19.30 miliarcseconds/year towards the north and 6.16 miliarcseconds/year east if we saw them in the horizon.

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 15.40 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.

Physical Properties (Colour) of DG Tauri

DG Tauri has a spectral type of K6Ve C. This means the star is a orange to red main sequence star.

Distance to DG Tauri

The Parallax of the star is given as 8.25 which gives a calculated distance to DG Tauri of 395.23 light years from the Earth or 121.18 parsecs. It would take a spaceship travelling at the speed of light, 395.23 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 24,994,995.05 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.
