What kind of star is Eta Geminorum?

What kind of star is Eta Geminorum?

Eta Geminorum (η Geminorum, abbreviated Eta Gem, η Gem), formally named Propus /ˈproʊpəs/, is a triple star system in the constellation of Gemini. It is a naked-eye variable star around 380 light years from the Sun.

What color is epsilon Geminorum?

yellow-hued
Epsilon Geminorum is radiating around 8,500 times the luminosity of the Sun from its outer atmosphere at an effective temperature of 4,662 K. It is this temperature that gives it the yellow-hued glow of a G-type star.

What color is the star propus?

red
Its proximity to Tejat also gave it the no-longer-used monkier “Tejat Prior.” Propus is a third magnitude (3.23) grand red giant star, one of the rather few bright cool (3600 Kelvin) class M (M3) stars in the naked-eye sky, its orange-red color rather obvious through binoculars.

What is the apparent magnitude of ETA in Gemini?

Propus, also designated as η Geminorum (eta Geminorum), is a variable and multiple giant star in the constellation of Gemini. Propus visual magnitude is 3.28.

How long will Pollux last?

The star’s estimated age is 724 million years. Pollux is believed to have started its life as a main sequence star of the spectral type A, but eventually spent its supply of hydrogen and evolved into an orange giant. It will keep getting bigger until it reaches the end of its life cycle.

How did Pollux get its name?

The name Pollux comes from a legend from both the Greek and Latin – Roman cultures. Pollux and Castor were twins and they were called Dioscuri in Greek, and the Gemini in Latin. The twins would help sailors in their time of need.

Is the star Bellatrix on the main sequence?

Bellatrix is a bluish main sequence star with the stellar classification B2 V. It has the spectrum of a giant, which is why a number of sources cite the spectral type of a giant, B2 III. Both the Simbad and NED databases give the spectral type B2 V, indicating that the star is still a hydrogen-fusing dwarf.

Is Pollux the North star?

At an apparent visual magnitude of 1.14, Pollux is the brightest star in its constellation, even brighter than its neighbor Castor (α Geminorum). Pollux is 6.7 degrees north of the ecliptic, presently too far north to be occulted by the Moon.

What will happen to Pollux?

It will keep getting bigger until it reaches the end of its life cycle. As it is not massive enough to go out as a supernova, Pollux will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf.

Is Sirius a twin star?

Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The distance between the two varies between 8.2 and 31.5 astronomical units as they orbit every 50 years.
