T Cephei is a red giant of spectral type M6-9e with an effective temperature 2,400 K, a radius of 329 R☉, a mass of 0.55 M☉, and a luminosity of 5,700 L☉. If it were in the place of the Sun, its photosphere would at least engulf the orbit of Mars.

Dec 21, 2004 · An easy star-hop about 3° southwestward from Alfirk (b Cephei) will bring you to the long-period variable star T Cephei. Once you think you’ve located it in binoculars, you’ll know for sure when you notice its red hue. The color is even more striking in a telescope.

Cepheus is a large constellation in the northern sky. It represents King Cepheus in Greek mythology. It is home to the large stars VV Cephei and the Garnet Star (Mu Cephei), the Wizard Nebula and the Fireworks Galaxy.

T Cephei is a red giant star. The brightness changes seen are primarily due to pulsations in the star’s outer layers. However, these outer layers are also sufficiently “cool” for it to be possible for some very simple molecules to form when the expansion phase causes further cooling and to then break up when the subsequent contraction ...

T Cephei is a Mira variable star in the constellation Cepheus. Located approximately 600 light-years distant, it varies between magnitudes 5.2 and 11.3 over a period of around 388 days.

T Cephei is a red supergiant star 329 times larger than the Sun. [1]

The bright orange star in the upper left (north is to the left in this image) is T Cephei, a red giant with about the same brightness as HD 200775, but much closer to us. T Cephei is only about 614 light years from earth and is at the opposite end of its life from HD 200775.

θ Cephei is a giant star of spectral class A7 in the constellation of Cepheus. θ Cephei visual magnitude is 4.22. Because of its moderate brightness, θ Cephei is easily visible to the naked eye from locations with dark skies, while it might be barely visible, or not visible at …

Cepheus is the name of two mythological kings. One was the son of Aleus, from Arcadia. He would become the king of Tegea (a community on the Peloponesian peninsula), would father twenty children, and would sail with Jason as an Argonaut. The other Cepheus was the son of Belus, king of Egypt (who was himself the son of Poseidon).

T Cephei. T Cephei is already in the late stage of its life. It is a red giant classified as a Mira variable star. Mira variables are late-stage pulsating stars. The apparent magnitude of T Cephei changes between 5.2 to 11.3. It is more luminous than the Sun by about 5,700 times. W Cephei
