What is the parallax angle of rigel?
.2 arc sec
If lines are not parallel can you still determine the angle measure?
yes you can still determine the angle measure!
How can you determine which angle is the largest in a triangle?
The largest angle in a triangle is opposite to its longest side
Determine the measure of the angle that is the supplement of 53 degree?
The supplementary angle of 53 degrees is 127 degrees
How do you use a right angle to determine the classification of another angle?
YOU can use a right angle by making it small to make it acute or you can make it big so it is obtuse
Why can't the parallax effect be used to measure distances to other galaxies?
The parallax angle of such distant objects is way too small to be measured. In general, the farther away an object, the smaller is its parallax angle.
What can parallax be used to determine about a star?
Parallax is a method used to find the distances of stars.
What is the parallax angle of rigel?
.2 arc sec
How does parallax shift varies with distance?
The closer the star, the greater the parallax angle, which is why you can't measure the distance to very distant stars using the parallax method.
Parallax would be easier to measure if?
Parallax would be easier to measure if the Earth were farther from the sun. This way, there will be a wider angle to the stars using the parallax method.
What is a parallax measure?
Parallax is an apparent displacement or difference of orientation of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. The term is derived from the Greek παράλλαξις (parallaxis), meaning "alteration". Nearby objects have a larger parallax than more distant objects when observed from different positions, so parallax can be used to determine distances.See Link for more information.
What is parallax bar?
A parallax bar or stereometer is a simple measuring device that is used to determine the height of objects in photographs.
Does the star Sirius or Betelgeuse have a greater parallax angle?
Sirius will have a greater angle, because it is closer to us.
If a star's parallax angle is too small to measure what can you conclude about the stars distance from earth?
You can conclude that it is farther than a certain distance. How much this distance is depends, of course, on how accurately the parallax angle can be measured.
What is Often used to determine the distance to nearby stars?
parallax
Most stars have such small parallax shifts that accurate measurement is always possible?
On the contrary, if the parallax angle is too small, it can't be measured accurately.
Why would astronomers measure the parallax angle of a planet or star?
It's distance
