No, the position of a star as seen from Earth is not the true position of the star in space. The light we see from stars is often from thousands or millions of years ago due to the vast distances they are located from us. Their current position may have changed since that light was emitted.
What else can I help you with?
If the distance between us and a star is doubled the apparent brightness is decreased by a factor of four true or false?
True. The apparent brightness of a star is inversely proportional to the square of the distance between the star and the observer. So if the distance is doubled, the apparent brightness will decrease by a factor of four.
What does the Doppler affect tell astronomers about a star?
The star attracts the planet; the planet attracts the star. As a result of the latter, the star changes position. If this change is such that the star moves away from us during one part of the planet's orbit, and towards us at another (or more generally, the star's speed towards us, or away from us, changes slightly), then this can be detected as a Doppler shift.
What star exploded a few years ago and could be seen from Maryland or East Coast of the US I distinctly remember seeing the sky light up at 1am ish and hearing about it on the radio a few days later?
It was not an exploding star.
Is it true that two stars that have the same brightness are the same distance from earth?
Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright star.
Why cant we see the second closest star to earth?
The second closest star to Earth, Proxima Centauri, is too faint and dim to be seen with the naked eye from Earth. It is a red dwarf star located over 4 light-years away from us, making it challenging to detect without the aid of a telescope.
Why north star important to the aborginal people?
If it's important to anybody, that's because it's a relatively bright star that always remains more or less in the same position, as seen by us.
What statement is true about a star with a greater shift in its spectrum than another star?
The star with the greater shift moves towards us, or away from us, faster.
What is the brightest star seen from southeast US?
The brightest star visible from the southeast US is Sirius, also known as the Dog Star. Sirius is part of the constellation Canis Major and is easily identifiable in the night sky due to its brilliance.
Why does the sun appear larger than other star when seen from earth?
It's closer to us
True or false the us general in Korea wears four hats filling four us four star positions these are cdrunc cdrcfc cdrusfk the senior us military officer in Korea?
True
If the distance between us and a star is doubled the apparent brightness is decreased by a factor of four true or false?
True. The apparent brightness of a star is inversely proportional to the square of the distance between the star and the observer. So if the distance is doubled, the apparent brightness will decrease by a factor of four.
Is there a baby blue star?
YEP it's name MALGAN after me and my friend(true to us) :D
How does imaging determine how fast a distant galaxy is moving away from Earth.?
The star's spectrum is analyzed; certain lines in the spectrum, which have a fixed position, will change their position when the object moves away from us or towards us.
What does the Doppler affect tell astronomers about a star?
The star attracts the planet; the planet attracts the star. As a result of the latter, the star changes position. If this change is such that the star moves away from us during one part of the planet's orbit, and towards us at another (or more generally, the star's speed towards us, or away from us, changes slightly), then this can be detected as a Doppler shift.
What does the red star on a 5 dollar bill mean?
The modern US five dollar bill (or note) does not have a red star on it. some older versions did carry a seal printed in red, but this would hardly be seen as a star.
What is difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
What does the emo star mean?
The emo star is actual a nautical star. The nautical star is usually seen as a tattoo representing membership in the US Navy or Marine Corp. The symbol represents the five pointed star of the US flag and the red/black color pattern represents the compass rose found on old nautical maps. I do not understand why emo's get the tattoo or what it means to them.
