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

Location of EI Cancri A

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 EI Cancri A, the location is 08h 58m 15.125 and +19 45 47.02 .

Physical Properties of EI Cancri A

EI Cancri A Colour and Temperature

Based on the star's spectral type of M8Ve , EI Cancri A's colour and type is red main sequence star. Based on the star's spectral, the stars temperature is between 2,400.00 and 3,700.00 degrees kelvin.

Distance to EI Cancri A

The Parallax of the star is given as 176.60000 which gives a calculated distance to EI Cancri A of 18.47 light years from the Earth or 5.66 parsecs. It is about 108,578,210,642,701 miles from Earth.

The star is roughly 1,167,450.67 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 EI Cancri A

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.
