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.
To calculate the angle between two stars, you need to know their coordinates in the sky, typically given as right ascension and declination. You can then use spherical trigonometry to determine the angle between them. This calculation involves using the cosine formula to find the angle based on the difference between the two stars' coordinates.

What tool is used for ship navigation using the stars?
A sextant is a tool used for ship navigation by measuring the angles between celestial objects, typically the stars, and the horizon. This information can then be used to calculate the ship's position on a nautical chart.
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?
Stellar parallax is the apparent shift in the position of a star when viewed from different locations in space, due to Earth's orbit around the Sun. By measuring this shift, astronomers can calculate the distance to the star. This method is particularly effective for nearby stars.
Did explorers use a telescope to navigate with the stars?
Explorers did not typically use telescopes for navigating with the stars. Instead, they used tools like the astrolabe or quadrant to measure angles between celestial objects, allowing them to determine their position on Earth. Telescopes were primarily used for observing distant objects in space.

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 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.
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. The angles which lie between 0° and 90° are said to lie in the first quadrant.
