ZZ Ceti

ZZ Ceti is a white dwarf star that can be located in the constellation of Cetus. The description is based on the spectral class. ZZ Ceti is not part of the constellation but is within the borders of the constellation.

Location of ZZ Ceti

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 star is compared to the celestial equator and is expressed in degrees. For ZZ Ceti, the location is 01h 36m 13.6155835488 and -11` 20° 32.631811638 .

Proper Motion of ZZ Ceti

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 -116.45 miliarcseconds/year towards the north and 460.85 miliarcseconds/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 (Colour) of ZZ Ceti

ZZ Ceti has a spectral type of DA4.0 C. This means the star is a white dwarf star.

Distance to ZZ Ceti

The Parallax of the star is given as 30.52 which gives a calculated distance to ZZ Ceti of 106.85 light years from the Earth or 32.76 parsecs. It would take a spaceship travelling at the speed of light, 106.85 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 6,757,187.97 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.
