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.
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 a angle with 90o
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
It is 754.81 milliarcseconds. Also, the star is Rigil Kentaurus, not Rigel which is the name of another star.
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.
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 the Earth were farther from the sun. This way, there will be a wider angle to the stars using the parallax method.
Sirius will have a greater angle, because it is closer to us.
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.
On the contrary, if the parallax angle is too small, it can't be measured accurately.
It's distance
Parallax
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.
It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
The parallax should get smaller and harder to notice although in astronomy there are techniques used to find the parallax of stars by using the Earth's position around the sun to find the distance of the stars.
