Astronomers use the term magnitude to compare the brightnesses of stars. Really bright stars are 1st magnitude while the faintest we can see with the naked eye are about magnitude 6. A 12 inch telescope can see down to about magnitude 14 or 15. Hubble Space Telescope can see down to about magnitude 27.

What are the 3 ways in which stars may differ from each other?
Brightness, Color and mass
What are stars and how are they different from each other?
Well, stars differ in size, color, temperature, brightness, and age. Plsss likee if this helped you on ur hw.! or also comment.!
Two stars whose apparent magnitudes differ from each other by five magnitudes have a ratio of brightness of?
About 97.7 (calculated as 2.55)
Eclipsing binary star in Perseus?
An eclipsing binary star in Perseus is a system where two stars orbit each other in such a way that they periodically pass in front of each other, causing eclipses and variations in brightness as viewed from Earth. By studying these changes in brightness, astronomers can determine important properties of the stars, such as their masses and radii.
Why do stars appear different from each other when observed?
Stars appear different from each other due to variations in their size, temperature, distance from Earth, and intrinsic brightness. Larger or hotter stars emit more light and can appear brighter than smaller or cooler ones. Additionally, distance plays a crucial role; stars that are farther away appear dimmer than those that are closer, even if they are intrinsically similar in brightness. Lastly, factors like interstellar dust can also affect the light we receive, altering a star's apparent color and brightness.
What causes the apparent brightness or size of stars constellations and galaxies?
The size of stars depends on their mass and the stage of their life cycle. Constellations are just stars which happen to lie in the same general direction from Earth, and have nothing really to do with each other. Apparent brightess of a star or galaxy is the result of its intrinsic brightness and its distance from us.
Do stars repell each other if they have magnetism?
Depending on their relative orientation, two magnets may attract or repel each other. However, the magnetism in stars is usually thought to be insignificant, compared to their gravitational force.
What is a triple star?
A triple star system is a system of three stars that are gravitationally bound to each other and orbit around a common center of mass. Triple stars can either be hierarchical, where two stars are closer to each other and the third is more distant, or trinary, where all three stars are relatively close to each other. Triple stars are relatively rare compared to binary stars.
What is an eclipsing binary?
An eclipsing binary is a system of two stars that orbit each other in such a way that they periodically pass in front of each other from our perspective on Earth, causing their combined brightness to fluctuate. By measuring these fluctuations, astronomers can determine properties of the stars, such as their sizes, masses, and orbital characteristics.
Why are stars different from each other?
Stars differ from each other primarily due to variations in their mass, age, temperature, and chemical composition. These factors influence their brightness, color, and lifespan. For example, more massive stars burn hotter and faster, leading to shorter lifespans, while smaller stars can exist for billions of years. Additionally, the presence of different elements affects their spectral characteristics and evolutionary paths.
How long does Brightness last in Antarctica?
Sources of brightness can be the sun, the moon and the southern hemisphere of stars. The brightness lasts 12 months out of every year. Under each of these light sources, Antarctica is 'bright' enough to navigate out of doors.
