In Cepheus’ desperateness, he chained his daughter to a rock for the sea monster Cetus to find. The galaxy has an apparent magnitude of 9.6 and lies at a distance of 25.2 million light years from Earth. Cepheus constellation map by IAU and Sky&Telescope magazine. In about 88,600 years, Kruger 60 will make its closest approach to the solar system and come within 1.95 parsecs. She boasted that she was more beautiful than the Nereids, sea nymphs. This constellation rotates around Polaris in a counter-clockwise direction throughout the night. Cepheus was one of the 48 constellations listed by the second-century astronomer Ptolemy. Phil Cunningham and band, Loch Katrine's Lady, Transatlantic Sessions (Glasgow, Feb 2013) - Duration: 4:46. This star is a red supergiant or also referred to as a hypergiant.

It is a white class A star, currently evolving from a main sequence star into a subgiant. Its radius spans between 7.5 and 8.8 Astronomical Units. Cepheids typically form with masses 3-30 times that of the Sun, then pass through the main sequence stage as B-class stars and, once they have burnt up the hydrogen in their core, their helium core loses stability and begins to contract and expand at regular intervals and they undergo stages of nuclear burning. “The King with a Crown of Stars”. This star rotates at a very high speed, at least 246 km/s, and completes one revolution in approximately 12 hours.

Airbus awards Ethiopian for its agility and resilience During the COVID–19; Cainiao teams up with Ethiopian Airlines to launch cold chain service for vaccine transportation The –ev suffix stands for “spectral emission that exhibits variability.” The star is a slow rotator and takes about 51 days to complete a single revolution, at a rotational speed of 28 km/s. It is unstable and expected to explode as a supernova in the relatively near future, which might translate into several millions of years. . Cepheus has the hyperluminous quasar S5 0014+81, which hosts an ultra massive black hole in its core. Luckily, the hero Perseus found the princess first, rescued her and killed the monster. It has a diameter of 1.753 billion km. Since their luminosities are directly tied to their pulsation periods, astronomers only need to measure the stars’ visual magnitude to determine their distance and the distances of the galaxies where the stars are located. It is eight times more massive than the Sun, about 3,600 times more luminous, and it has a surface temperature of 4,310 kelvins. The orange hypergiant, RW Cephei, is one of the largest stars known to the human race. Cepheus has one star with known planets and contains no Messier objects.
