The brightest star in this constellation is the Beta Cancri with a magnitude of 3.5. satellite operation launched in 1989 for four years. The Sun's radius is 695,800km, therefore the star's radius is an estimated 42,443,800.00.km. It is also sometimes referred to as Alpha Tauri. An older star would have a high metallicity whereas a new star would have a lower one. In Cancer. Beta Cancri is known as Tarf, or Altarf, which is the star’s traditional name. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. The alpha star in Cancer is actually a dimmer star at magnitude 4.26. Proper Motion details the movements of these stars and are measured in milliarcseconds. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. Also notable in the Cancer constellation stars is the star Alpha Cancri, also known as Acubens. The second star is more far and is about 65 times the distance of Pluto from sun which means its orbital period is 76,000 light years.

In the Washington Double Star Catalogue, Tarf has the designation WDS J08165+0911A. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. The star's metallicity is -0.290000, this value is the fractional amount of the star that is not Hydrogen (X) or Helium (Y). Asellus Australis is also used as a guide in finding one of the reddest stars in the sky, X Cancri. Eccentricity is measured as a decimal from 0 to 1, the closer to zero, the more circular the orbit is. The star is moving -49.24 ± 0.10 milliarcseconds/year towards the north and -46.82 ± 0.19 milliarcseconds/year east if we saw them in the horizon. The Beta Cancri (Al-Tarf) is the brightest star in the constellation, having a magnitude of 3.5; while the Delta Cancri (Asellus Australis) is the second brightest star with a magnitude of 3.94.
