DX Cancri (Flare Star) Facts

DX Cancri Facts

  • DX Cancri is a Flare Star that can be located in the constellation of Cancer. The description is based on the spectral class.
  • DX Cancri is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (M.5V) of the star, the star's colour is red .
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • DX Cancri has a radius that is 0.11 times bigger than the Suns. Radius
  • The star is calculated at being about 11.83 light years away from us. Distance

DX Cancri's Alternative Names

DX Cancri has alternative name(s) :- GJ 1111, Gliese 1111.

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

Location of DX Cancri

The location of the Flare 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 DX Cancri, the location is 08h 29m 49.345 and +26° 46` 33.74 .

Radial Velocity and Proper Motion of DX Cancri

Proper Motion

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 -610.90 milliarcseconds/year towards the north and -1,112.20 milliarcseconds/year east if we saw them in the horizon.

Radial Velocity

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 9.00000 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 of DX Cancri

DX Cancri Colour and Temperature

Based on the star's spectral type of M.5V , DX Cancri's colour and type is red Flare Star. The star has a B-V Colour Index of 2.08 which means the star's temperature is about 541 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

DX Cancri Radius

DX Cancri Radius has been calculated as being 0.11 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 76,538.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

DX Cancri Mass

The DX Cancri's solar mass is 0.09 times that of our star, the Sun. The Sun's Mass is 1,989,100,000,000,000,000,000 billion kg. which to calculate using this website is too large. To give idea of size, the Sun is 99.86% the mass of the solar system.

DX Cancri Apparent and Absolute Magnitudes

DX Cancri has an apparent magnitude of 14.81 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 17.01 Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.

Distance to DX Cancri

The Parallax of the star is given as 275.80000 which gives a calculated distance to DX Cancri of 11.83 light years from the Earth or 3.63 parsecs. It is about 69,544,138,164,762 miles from Earth.

The star is roughly 748,736.03 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 DX Cancri

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.
