It is a very small mass main sequence star (< 0.1M sun). Located in the constellation of Gemini, it is the nearest star in this constellation. Its mass is 46% that of the Sun, making it for a red dwarf positively obese. 55 Cancri Copernic « 55 Cancri B » redirige ici.

However, Dawson & Fabrycky (2010) revised these values, reporting a period of 0.7365 days and a minimum mass of 8.3 ± 0.3 M⊕. Whereas DX Cancri possessed only a little more than 1/1000th of the Suns visual luminosity, Lalande 21185 shines out at a mighty 2.5% , or about 40 times that of DX Cancri. It is located near the boundary with Auriga, 49 arcminutes away from the bright star Theta Gemino With an apparent visual magnitude of 14.81, it is much too faint to be seen with the naked eye. A star is an astronomical object that consists of a sphere of luminous plasma held together by its own gravity.

Astropedia 12.3: The chemical composition in most stars are Carbon, Helium, Hydrogen, and other heavier elements. Part of the constellation of Cancer, DX Cancri resides in the northern sky in the spring, and the southern sky in the fall. Database references; SIMBAD: data: 1 Cancri is a single star in the zodiac constellation of Cancer, positioned near the border with Gemini at a distance of around 470 light years from the Sun. Gliese 251, also known as HIP 33226 or HD 265866, is a star located about 18 light years away from the Solar System. I'm sorry, but I don't know its surface temperature, despite a quick look on "Wikipedia". Visually viewing this star requires a telescope with a minimum aperture of 16 in (41 cm).

Like other types of star, red dwarfs may be accompanied by planets. DX Cancri is another red dwarf and flare star. Based on the star's spectral type of G0V , Tegmine's colour and type is yellow main sequence star. DX Cancri, at 11.8 ly distance the 18th closest star system to our own sun, is unfortunately the first star on our list, as it is also the hardest to find. With an apparent visual magnitude of 14.81, it is much too faint to be seen with the naked eye.

Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 5,000 and 6,000K based on the notes from Harvard University. Achernar A DX Cancri (b) Use the table above to help explain in detail the similarities and differences between Achernar A and DX Cancri. Hydrogen goes into chemical reaction continuously, thus the hydrogen atom fuses in order to create helium in their cores. Italiano; English; We report on the XMM-Newton observation of DW Cnc, a candidate intermediate polar candidate whose historical optical light curve shows the existence of periods at ≃38, ≃86, and ≃69 min, which were interpreted as the white dwarf spin, the orbital and the spin-orbit beat periodicities. A dynamical analysis shows that the system has to be almost coplanar in order to be stable for the age the system. 55 Cancri e is a super-Earth which appears to exhibit extreme variations in brightness temperature.
