What is the size of the star name polaris?
The main star in the Polaris system has a mass of 4.5 Suns and a radius which is 46 +/- 3 times as big as the Sun's.
Is the star Polaris high mass or low mass?
I'm convinced that this is how a lot of wars start ... people talking to each other using words that mean different things to different people. You're talking 'high' and 'low', which are certainly relative words at best, without mentioning anything else that might tell us what you're thinking of to compare to. Compared to you or me, or either of my dogs, or a car, or a continent, or the whole Earth, the star Polaris is certainly an enormous mass. Compared to any stable black hole, Polaris is a tiny mass. It doesn't even have enough mass to ever become a black hole when it's done shining. Polaris is estimated as six (6) solar masses. That's more massive than most main-sequence stars, less massive than the majority of high-mass stars, and roughly the mass of our sun six times over. -- Compared to anything but stars, the mass of Polaris is huge. -- Compared to the mass of other stars, Polaris is somewhat above average, but probably not to the point where you'd need to call it especially high or especially low. Edit: A lot of this is missing the point. The terms "high mass" and "low mass" are technical terms used by astronomers. Astronomers can define what is meant. There is no exact definition, but a high mass star is normally considered to be one that will eventually become a "Type II Supernova". That requires a mass at least 8 times the Sun's mass. In that case, Polaris is clearly not a "high mass" star, according to the definition. However, it's probably best to call Polaris a "medium" or "intermediate" mass star rather than a "low mass" star. Note: A slight complication is that Polaris is a triple star system. I assume we are talking about the main star in this system.
Is polaris bigger than your sun?
Polaris is a triple star system. The main components is a yellow super giant with a mass more than 5 times that of my sun.
What galaxy is the Polaris star in?
No, Polaris is a star in the constellation Ursa Minor. It is also known as the North Star.
What is the colour of Polaris?
Polaris or Alpha Ursa Minoris is actually a multi star system of 3 to 5 known stars. Polaris A is a yellowish white giant or supergiant star approx 6 solar masses in mass. Polaris Aa is yellowish white dwarf star in close association with Polaris A (18.5 AU). Polaris B is a yellowish white star about 1.5 solar masses about 2,400 AU from Pol A. All 3 stars are F type stars. A - F7Ib-II, Aa - F7 Dwarf, B - F3V There are 2 other stars thought to be associated with Polaris. Polaris C & D.
What isthesize of polaris?
Polaris is a multiple star, comprising three stars. The main star (Alpha Ursa Minor Aa) is a yellow supergiant with the mass of 4.5 times that of the sun. A smaller companion, Alpha UMi Ab has 1.26 solar mass, while Alpha UMi B is 1.39 solar masses.
What are the characteristics of the star polaris?
Polaris is a system of 5 starts: a yellow super-giant whose mass is approx 4.5 times that of the Sun. It has two companions which are around 30% as massive and two more which are smaller and further away.
What is the color size and apparent brightness of Vega Polaris and Arcturus?
Arcturus is orange in color, and has a mass of 2.188E30 kg. Vega has an apparent magnitude of 0.03, a white color, and the size is unknown. Comments. That answer does not fully answer the question. For example there's nothing about Polaris.
Is Polaris A a Red Giant?
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
Is a red giant a polaris?
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
