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 was the disadvantage off using the north star to determine direction?
some time there is a Storm and you can't see the star so that is the disadvantage of using a north star
What would be a common task for an astronomer?
using a telescope to determine the coordinates of a star
What are three physical factors that determine a star's brightness?
Age of the star, size, and temperature. The answer is in another post that I saw.
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.
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=)
Three ways you can determine if a substance is a mixture or a pure sample.?
One way is if it can be physically combined.
Identify and discuss three ways to determine training needs in an organisation?

What three tasks do an astronomer complete most days?
1. They locate the moon to determine the date. 2. They find the north star to determine their location. 3. The search for new objects.
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.
How do you determine a stars luminosity?
To determine a star's luminosity is from size and temperature.
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 factor is not used to determine a star's apparent magnitude?
how dense the star is
