Stars do not have arms.
3 names of where you would find an acute angle is: Triangle, cone and a star.
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
If a star's azimuth is 90 degrees, it is located directly east on the horizon. An altitude of 45 degrees means that the star is positioned halfway up in the sky, forming a right angle with the horizon. Therefore, this star would be visible in the eastern sky at an angle that is halfway between the horizon and the zenith.
The sextant.
The Meridian Star was created in 1898.
That depends on the date, and on the time of day. Once a day, this star - or any other star for that matter - will cross the meridian. Or twice a day, but the other crossing is usually below the horizon.
The distance around the map that the star spans is called the circumference.
The Hour of the Star was created in 1977.
The amount of time between successive passes of the star Sirius across the meridian is 23 hrs 56 minutes.
The ISBN of The Hour of the Star is 978-0811219495.
Hour of the Star was created in 1985-02.
The duration of Hour of the Star is 1.6 hours.
Between two points - like a star and Earth - you would have a line, not an angle. Angles may be indicated between two stars - that is, the angle would be star 1 - Earth - star 2.
the answer is 5 each tip of the star is a acute angle and each angle on the inside of the star is an obtuse angle. there are 5 obtuse angles and no right angles.
We would typically use a sextant to measure the angle of a star above the horizon.
