What does the angle of parallax determine?
Accuracy of readings of e.g. meters and certain optical instruments. Parallax is also used in astronomy for calculating distances to(astronmically)far-away objects.
Why the same galaxy can appear to have different shapes to different observers?
It can appear to have different shapes because of the viewers point of view. Also Parallax can have an affect on it! Google it for further research look up Galaxy Parallax. Glad I Could help! Another opinion: All observers see the same shape of any galaxy, and no galaxy exhibits parallax, as long as we're talking about observations taken anywhere in our solar system.
A right angle is an angle that has a?
A right angle is a angle with 90o
What type of angle is a 98 angle?
An angle of 98 degrees is an obtuse angle
What angle does a hemisphere have?
what angle does a hemisphere have what angle does a hemisphere have what angle does a hemisphere have
What is the parallax angle of rigel kentaurus?
It is 754.81 milliarcseconds. Also, the star is Rigil Kentaurus, not Rigel which is the name of another star.
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.
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.
Does the star Sirius or Betelgeuse have a greater parallax angle?
Sirius will have a greater angle, because it is closer to us.
The star Sirius is known to be 8.6 light years away What is the parallax angle?
The parallax angle of Sirius is approximately 0.38 arcseconds. This value indicates the shift in position of the star as seen from Earth due to its motion around the Sun. The parallax angle is used to calculate the distance to nearby stars.
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.
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.
Describes the angle between your line of sight and the top of a painting that you are looking at?
Parallax
How does parallax shift varies with distance?
The parallax shift decreases as distance increases. Objects that are closer to an observer will have a larger apparent shift in position when the observer changes their viewing angle, while objects that are farther away will have a smaller apparent shift in position. This difference in the amount of shift is what allows astronomers to use parallax to calculate the distances to nearby stars.
A star has a parallax of 0.75 of arc How far away is this star in light years?
The distance to the star can be calculated using the parallax angle (in arcseconds) and the formula: distance (in parsecs) = 1 / parallax angle (in arcseconds). Given a parallax of 0.75 arcseconds, the star is approximately 1.33 parsecs away. Converting parsecs to light years (1 parsec ≈ 3.26 light years), the star is about 4.34 light years away.
What does the angle of parallax determine?
Accuracy of readings of e.g. meters and certain optical instruments. Parallax is also used in astronomy for calculating distances to(astronmically)far-away objects.
If a star's parallax angle is too small to measure what can you conclude about the star's distance from earth?
It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
