What are characteristics of stars?

What are characteristics of stars?

A star can be defined by five basic characteristics: brightness, color, surface temperature, size and mass.

What are the four characteristic of stars?

Key Concept: Characteristics used to classify stars include color, temperature, size, composition, and brightness.

What are the characteristic of large stars?

giant star, any star having a relatively large radius for its mass and temperature; because the radiating area is correspondingly large, the brightness of such stars is high.

What are the characteristics of a galaxy?

Galaxies are sprawling systems of dust, gas, dark matter, and anywhere from a million to a trillion stars that are held together by gravity. Nearly all large galaxies are thought to also contain supermassive black holes at their centers.

What are the characteristics of an open cluster of stars?


Characteristic: Open Clusters: Globular Clusters:
Shape: Irregular Spherical
Color (Common): Red or Blue Red
Metallicity: High Low
Location: Disk of Galaxy Halo of Galaxy

What are 3 characteristics of spiral galaxies?

Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

What is the characteristic of a star that determines how it will end its life?

What property of a star determines how the star will end its life? Mass- the life cycle is determined by the mass of the star. you see, the heavier the star, the shorter its lifespan. very heavy stars only live ~100.000 years, while stars like the sun can last billions of years.

Which two factors determine the characteristics of a star?

By observing the motion, spectrum , and luminosity of a star, astronomers can determine its age, mass, chemical composition, and many other properties. The primary factor in determining the type of evolution a star goes through is its total mass .

What are characteristics used to classify a star?

List the 5 Characteristics used to classify stars. color, temperature, size, composition, and brightness. What does a star’s color reveal? It’s surface temperature.

What are three characteristics to classify stars?

Astronomers classify stars according to their physical characteristics. Characteristics used to classify stars include color, temperature, size, composition, and brightness. Stars vary in their chemical composition.

What are the physical attributes of a star?

There are a number of physical characteristics that vary for each of the different types of star. These include the surface temperature, luminosity (brightness), mass (weight), radius (size), lifetime, prevalence in the cosmos, and point in the stellar evolutionary cycle.
