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.

BeauTo 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.
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.
