The moon subtends an angle from earth of approximately 1/2 degree. Stars twice as far apart as the diameter of a full moon would therefore be 1 degree apart. Your fist at arm's length subtends approximately 10 degrees. So two stars three fists apart would be about 30 degrees.

Binary stars can be used to calculate the of stars?
Double stars, also called binary stars, are valuable to astronomers because they are the only stars of which astronomers can easily calculate their mass. They are bound to each other by gravity and orbit about a common center. The time it takes for one star to orbit the other depends on the distance between the two stars and their masses.
Are there any stars between Galaxies?
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
What is a stars parallax?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
Why do we measure the movement of stars?
Parallax is the apparent change in position of an object when you look at it from different angles. Astronomers often us parallax to measure distances to nearby stars. This method can be used to determine stars' distances up to 400 light-years from Earth.
What is the difference between meteors and stars?
Meteors are made up of rocks and ice and dust from space where as shooting stars are falling stars.
How do you calculate the difference between 2 angles?
y=7.5x then determine x when y = 90
Which stars have the largest parallax angles-?
the stars nearest Earth

How do you calculate angles?
Through a protractor!!!
How do you calculate angles from tube bending XYZ coordinates?
It is the analytic geometry formula for finding the angle between two planes.
How do you calculate parallel line angles?
Parallel lines do not meet and so do not form angles.
How do you calculate interior angles in polygons?
You cannot calculate interior angles in a polygon. You can only calculate their sum. The sum of all the interior angles of an n-sided polygon is (n-2)*180 degrees. So for example, the interior angles of a triangle (n = 3) sum to 180 degrees. But the individual angles can be (1,1,178), or (30,60,90) or infinitely many other combinations.
How do you calculate angles in a kite?
Record how long they are first.
How to calculate the angles of an isosceles trapezium?
It will have 2 pairs of equal angles that add up to 360 degrees
What are the quadrant angles?
Quadrant angles are the angle lies in different quadrants. The angles which lie between 0° and 90° are said to lie in the first quadrant. The angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant and angles between 270° and 360° are in the fourth quadrant Quadrant angles are the angle lies in different quadrants.

What are the angles of an old single cut diamond?
Although the value of the angles are not given in this illustration, you can follow the link, below, print the page, and calculate the angles.
