You have two main categories of magnitude. Apparent magnitude is how bright a star appears to be when we look at it. Different stars appear to have different levels of brightness. However all of the stars are different distances away. So a very bright star might be so far away that it looks very faint while a star that is not actually as bright as it appears far brighter because it is much nearer to us. Absolute magnitude measures the real brightness of stars, or how bright they would be if they were all the same distance from us.
What else can I help you with?
A star might be much brighter than it appears to be This is called the star's absolute magnitude The difference in apparent magnitude and absolute magnitude is due primarily to the star's?
distance from the Earth. The apparent magnitude of a star is how bright it appears from Earth, while the absolute magnitude is how bright a star would be if it were located at a standard distance of 10 parsecs away from Earth. The difference in magnitude is primarily influenced by the star's distance, with closer stars having a smaller difference and more distant stars having a larger difference between their apparent and absolute magnitude.
Why does Arcturus star have greater absolute magnitude than the sun buy a much lower apparent magnitude?
The apparent magnitude is how bright the star appears to us, but stars are all at different distances so that a star that is really bright might look dim because it is very far away. So the absolute magnitude measures how bright the star would look if it was placed at a standard distance of 10 parsecs. When the absolute magnitude is greater than the apparent magnitude, it just means that it is closer than 10 pc. The brightest stars have absolute magnitudes around -7.
What is the absolute magnitude of most blue stars?
They would have different sizes, but all much larger than our Sun, being hundreds of times larger. If some of them were where our Sun is now, we would be inside the star because they would reach out beyond where we are in relation to our Sun.
How do the elements that are created inside stars get out?
A small amount might get out with solar (or stellar) wind. But mainly, at the end of the life of larger stars, there is a violent explosion called a supernova, that ejects a large part of the star's material into space.
Which of the following might be evidence for an extrasolar planet?
Potential evidence for an extrasolar planet includes observing a star's wobble due to the gravitational pull of an orbiting planet, detecting a dip in a star's brightness as a planet passes in front of it (transit method), or directly imaging a planet near a star using advanced telescopic techniques.
What is the magnitude weakest possible earthquake recorded?
it might be 1 magnitude.
Why is it important for some numbers to be written in scientific notation form?
When numbers get very large or very small, all those zeros get confusing. If you made a mistake counting them you might make an error of vast magnitude.
Why would a man lie about having a baby?
There could be many reasons. He might think that you think it's cute that he has a child or maybe he just wants to seem macho...men are confusing.
What are the sun and its orbiting planets known as?
Stellar system being the generic term. There are no other Solar systems; those are stellar systems. Specific names might be siriusian, Miran, betelgeussian...etc. Which means that our stellar system might be called The Sol System, or The Solar system. They are also known as celestial bodies.
How might you explain Alexander and decision not to kill anyone who took sanctuary in the temple?
it is pretty confusing
A star might be much brighter than it appears to be. This is called the star's absolute magnitude. The difference in apparent magnitude and absolute magnitude is due primarily to the star's -?

Who might ask the witness during the redirect examination questions to clarify anything that might be confusing?
defence
What did the mound builders contribute to pottery?
I think they might have done rope pottery? I might be confusing that with my Japanese history...
During the redirect examination the might ask the witness more questions to clarify anything that might be confusing?

What is the apparent magnitude of a main sequence star?
The apparent magnitude depends on distance, and without that information, it's literally impossible to tell what it might be.
Why might someone have a Koi pond?
There are many reasons why might have a Koi pond. One might have a Koi pond for religious reasons, spiritual reasons, or simply for decoration purposes.
Why can you not understand homework from your school?
There could be many reasons. It might be that you are not listening well in class. It could also be that the homework itself is confusing. Ask other students if they are having trouble understanding the homework and if they are, talk to the teacher about it. If others are not having problems understanding it, it might be that you need some extra help with it.
