How do scientists classify a star by size?
Scientists classify stars by size based on their mass. Stars can be categorized as dwarf stars (like our Sun), giant stars, or supergiant stars, with the size increasing as the mass of the star increases. The classification can also include specific categories such as red dwarfs, white dwarfs, or blue giants, depending on additional characteristics.
What does the hr diagram compare?
The HR diagram compares the luminosity (brightness) of stars against their surface temperature or spectral type. This plot helps astronomers classify stars based on their intrinsic characteristics and evolutionary stages.
Who are the astronomer divided the stars into six magnitudes of brightness?
The astronomer who divided stars into six magnitudes of brightness was Hipparchus, a Greek astronomer active in the 2nd century BCE. He developed a system to categorize stars based on their apparent brightness, with the first magnitude representing the brightest stars and the sixth magnitude representing the faintest stars visible to the naked eye. This magnitude scale laid the groundwork for modern astronomical classification of stellar brightness.
What do astronomers plan to fined out by classify stars?

What traits do scientist use to classify stars?
Scientists use color, size, brightness, and temperature to classify stars.
What is the main characteristics used to classify stars?
age, brightness , color, bubblyness, yellowness , and heet
What are the three main characteristic used to classify stars?
The three characteristic are temperature, size, and brightness.
How are stars classifieds?
Stars are classified by their color, temperatures, sizes, and brightness, it could also be by composition and radiation.Scientists classify stars by color, luminosity, and temperature.
What characteristics are used to describe stars?
Stars can be described by their temperature, size (diameter), brightness (luminosity), color, composition, and age. These characteristics help scientists classify and study stars in the universe.
What are some characteristics used to classify stars?

What are the four characteristics that scientists use to classify stars?
Stars are classified by four different characteristics. Apparent magnitude (brightness) and absolute magnitude (how bright it would appear at 10 parsecs from the earth). Luminosity, another measure of brightness, compares the star to the sun's brightness. Spectral classifications are measured by the star's temperatures. Finally stars are signed a number by scientists through the Morgan-Keenan System.
What are the four variables astromeners use to classify stars?
The four variables astronomers use to classify stars are temperature, luminosity, size or radius, and mass. By analyzing these properties, astronomers can determine a star's position on the Hertzsprung-Russell diagram and classify it into different spectral types and stages of stellar evolution.
What are the two main properties that astonomers use to classify stars?
The surface temperature and the absolute magnitude, which is the brightness of the star when viewed from a standard distance of 10 parsecs.
