Population II stars are lower in "metals" than population I stars.
By metals, astronomers mean anything other than hydrogen and helium.

How big is a star compared to the earth?
It depends on what star you compare it to. Stars have many different sizes. Our sun is a star and it is approximately a million times larger than the earth.
Is a star bigger than a nova?
Some stars are
Where are the Population One and Population Two stars located in the Milky Way Galaxy?
Population I stars (metal-rich stars) are common in the Milky Way's spiral arms; Population II stars are more common in the galactic halo.For more details, you may want to read the Wikipedia article on "Metallicity". Note that in astronomy, "metal" is an informal name for elements other than hydrogen and helium. This usage is quite different from the usage in chemistry.
How do Population One and Population Two stars compare to each other?
Population I stars have more metals (heavier elements), and are generally younger, than the Population II stars. It is postulated that there are still older Population III stars, that have even less metals and are even older, but none have been discovered yet.
Are stars far away bigger than the sun?
The sun is a star itself. The sun is actually a very small star. There are stars that are WAY bigger then the sun.Like the VY Canis majoris star. The sun is invisible compared to that super giant star.
What are the main differences between stars and the sun?
The sun is a star. Its different to us than other stars because it is the closest to our planet.

What is bigger a planet or a star?
Stars are much bigger than planets. The only stars that are smaller than planets are neutron stars.
How does the red star and the blue star compare to the sun?
Our Sun is basically yellow. Our Sun's surface temperature is higher than that of a red star, and lower than that of a blue star.Other than that, it's hard to make comparisons, since both red stars and blue stars come in VERY different sizes.
What is in a star?
A star is made of hot gases. When they start out, they are almost entirely Hydrogen. During the main sequence, they fuse the hydrogen into helium which is heavier. They also produce smaller amounts of heavier elements like Carbon, Oxygen, Iron, Silicon and Neon. Some stars may contain other elements and earlier Population III and II stars are a bit different. They had less metals than more recent Population I stars like the sun.
How are population 1 stars and population 2 stars different?
Population 1 stars are typically young and metal-poor, found in the halo of a galaxy and formed from pristine gas. Population 2 stars are older and metal-rich, located in the disk of a galaxy and formed from gas enriched by supernova explosions of earlier stars.
How do star are more brighter than other stars?
Stars are more brighter than other stars because they have different characteristics that affect their luminosity. Luminosity is the amount of energy that a star emits per unit of time. It depends on the star's size, temperature, and distance from the observer. Some of the factors that make stars more brighter than other stars are: Size: Larger stars have more surface area and can emit more light than smaller stars. Temperature: Hotter stars have higher energy and can emit more light than cooler stars. Distance: Closer stars appear brighter than farther stars because their light has less space to travel and lose intensity.
Is a star bigger than a planet?
in most cases, a star is bigger than a planet. yet, both stars and planets have different sizes, such as a white dwarf star is smaller than Jupiter.
Is there any star bigger than star?
that question doesn't make sense. there are star that are one billion times bigger than our on solar system star, how ever bigger stars live a shorter life than smaller stars!
Suppose you see two stars a blue star and a red star what can you conclude about the two stars?
the blue star has a hotter surface temperature than the red star. (:
Does china have a different solar system than US?
No, though classic Chinese astronomy sees different "pictures" in the star patterns than are used elsewhere in the world, but the stars are the same.
