Astronomy is the branch of science that includes the study of stars, galaxies, and other celestial objects in the universe. Astronomers observe, analyze, and interpret the behavior and characteristics of stars to better understand their formation, evolution, and properties.
Some characteristics used to classify stars include their temperature, color, size (mass), luminosity (brightness), and spectral type. By studying these characteristics, astronomers can classify stars into different categories such as main sequence stars, giants, supergiants, white dwarfs, and more.
People studied stars 100 years ago using telescopes, photographic plates, and spectroscopes. They would observe the positions, motions, and spectra of stars to better understand their characteristics, such as temperature, composition, and distance. This observational data was then analyzed and interpreted to advance our knowledge of the universe.
They were there, above their head most nights - they could not help but observe them.
People studied stars 200 years ago primarily through the use of telescopes equipped with lenses and mirrors to observe and analyze the positions, movements, and characteristics of stars. They also relied on manual calculations and observations to track the movements of stars in the night sky over time. Astronomy was a combination of observation, mathematics, and theory to understand the nature of stars.
To observe the stars, you would use a telescope.
An astronomer is a scientist who specializes in mapping and studying the fixed stars in the universe. They use telescopes and various instruments to observe and collect data on the positions, movements, and characteristics of stars to better understand the cosmos.
Stars vary in characteristics like brightness for example. Stars will also tend to differ in size and color when they are found.
At the Age of Exploration they used telescope to observe stars.

When you can observe something's characteristics, they are called physical traits. These are the things you can see, hear, smell.
You can observe an object's size, shape, color, texture, weight, and any other physical characteristics it may have.
