I think it is the milkey way beacause
it is the round shape and it has many
star and can go up to 200 miles per
hour.

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
What distance is the absolute magnitude and the apparent magnitude of a star would be equal if the star is seen at?
The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
Is the brightness of a star compared to other stars called its magnitude.?
No; the "magnitude" is how bright the star is. It can either mean:* The apparent magnitude = how bright it seems to us, * The absolute magnitude = how bright the star really is (i.e., how bright it would seem at a standard distance).
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 is the magnitude of Altair star?
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
What is the absolute magnitude of Altiar?
The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.
How bright a star actually is at a distance of 32.6 light years away from earth is?
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
How does the apparent-magnituede of a star differ from it absolute magnitude?
Absolute magnitude is how bright a star is. Apparent magnitude is how bright it looks to us (on Earth).
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
What distance is the absolute magnitude and the apparent magnitude of a star would be equal if the star is seen at?
The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
What is difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
How are absolute magnitude and apparent magnitude alike?
Absolute magnitude and apparent magnitude are the same because they are both ways on how to measure the brightness of a star. Absolute magnitude is how bright is the star if we will see it in a 32.616 light-years distance while apparent magnitude is the brightness of it that we see on Earth.
How bright a star actually is a distance of 32.6 light years from earth is called?
That's called the star's absolute magnitude.
Compare and contrast apparent magnitude and absolute magnitude?
Apparent Magnitude is the star's brightness as it appears from earth. absolute magnitude is the apparent brightness of a star if viewed from a distance of 32.6 light years away.
Compare apparent magnitude and absolute magnitude?
Apparent Magnitude is the star's brightness as it appears from earth, while, Absolute Magnitude is the apparent brightness of a star if viewed from a distance of 32.6 light years away.
How does apparent magnitude of a star differ from absolute magnitude?
Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.
