What are three factors that determine the apparent magnitude of a star?
Its real (absolute) magnitude; its distance from Earth; the amount of light that's absorbed by matter between the star and us (extinction); distortions due to gravitational lensing.
Do scientists uses how far away the star is to determine the brightness of the star?
yes sometimes
What tool is used to determine the place of star?
Sextant.
What is another term for star systems with three stars?
A triple star system.
How do you determine whether a star is moving closer or farther away from us?
To determine whether a star is moving closer or farther away, astronomers often use the Doppler effect, which causes the light from a moving star to shift in wavelength. If the star is moving closer, its light appears blue-shifted, meaning the wavelengths are compressed. Conversely, if the star is moving away, its light appears red-shifted, with the wavelengths stretched. By analyzing the spectrum of the star's light, astronomers can measure this shift and determine its motion relative to Earth.
What are three physical factors that determine a star's brightness?
Three physical factors that determine a star's brightness are its temperature (hotter stars are brighter), size (larger stars are generally brighter), and distance from Earth (the closer a star is, the brighter it appears).
What three factors determine the magnitude of star?
The apparent magnitude of a star is dependent on the star's size, temperature and distance from where it is observed. An absolute magnitude is determined by the same three factors, but the distance is fixed at 10 parsecs.
What three things determine which stars you see in the sky?
Your place on the earth, The brightness of the star, Its distance.
Three ways you can determine if a substance is a mixture or a pure sample.?
One way is if it can be physically combined.
How you can determine the star of a star planet?
You can determine star of a star planet by its color also you can determine its temperature by its color by:Joshua R. Dapitillo thanks=)

Binary star can be used to determine the of a star?
Mass
How do scientists determine the element present in a star?
By the star's spectrum.
What 2 factors determine a star's apparent magnitude?
There are three factors, actually. The star's size and temperature determine the absolute magnitude, or how bright the star really is. Those two factors can be considered as one - the star's absolute magnitude. The absolute magnitude combined with our distance from the star determines its apparent magnitude, or how bright the star appears to be from Earth. So, a big, hot, super bright star very far away may have the same apparent magnitude as a small, cool star that's fairly close to the Earth.
What are three factors that determine the apparent magnitude of a star?
Its real (absolute) magnitude; its distance from Earth; the amount of light that's absorbed by matter between the star and us (extinction); distortions due to gravitational lensing.
What factor is not used to determine a star's apparent magnitude?
how dense the star is
What instruments are used to determine the altitude of the north star?
Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
