We would typically use a sextant to measure the angle of a star above the horizon.
Altitude is the angle measured above the horizon.
altitude
The angle between the sun's position in the sky and the horizon is called the altitude of the sun. It is the measurement from the horizon to the center of the sun's disk. This angle changes throughout the day as the sun moves across the sky.
the angle between an object in the sky and the horizon
Altitude is the angle measured above the horizon.
Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
Almost . . ."Altitude" is the apparent angle of the object above the horizon.
The answer you're looking for is the Sun's altitude.
Yes, that method involves measuring the angle between your horizon and the North Star in the night sky, which is approximately equal to Earth's axial tilt of about 23.5 degrees. By determining this angle, you can indirectly calculate the tilt of Earth's axis.
66.5 degrees
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.
Sextant is used to measure the angle between any two visible objects.Its primary use is to determine the angle between a celestial object and the the horizon which is also know as objects altitude.
