Does the altitude of the north celestial pole equals your latitude?
The altitude (distance above the horizon) of the NCP is equal to your latitude north of the equator; ditto for the SCP in the Earth’s southern hemisphere. The circumpolar stars are within (latitude) degrees of the celestial pole. They have declinations greater than +(90-latitude) degrees for the northern hemisphere.
What is the altitude of the North Star from the North Pole?
90 degrees
Polaris is the North Star, located above the North Pole along the north celestial pole. When viewed from the equator it lies on the northern horizon (at an altitude of 0 degrees), and when viewed from the North Pole it lies directly overhead (at an altitude of 90 degrees).
What latitude is the north celestial pole?
90° N
Stand on the North Pole, latitude 90° N, and overhead will be the north celestial pole, declination +90°.
What is the altitude of an object in the sky that is seen directly above an observer?
Zenith and nadir [The zenith is the] point on the celestial sphere directly above an observer on the Earth. The point 180 degrees opposite the zenith, direclty underfoot, is the nadir. Astronomical zenith is defined by gravity, i.e. by sighting up a plumb line.
How do you find the north celestial pole?
To find Polaris, from a point in the Northern Hemisphere, face north and locate the Big Dipper (Plough) and Little Dipper asterisms. Looking at the “cup” part of the Big Dipper, imagine that the two stars at the outside edge of the cup form a line pointing upward out of the cup.
What is altitude of a celestial body?
The altitude measures the angle of the object above or below the observer’s horizon. Along with the azimuth, the ‘altitude’ of an object is used to define its position on the celestial sphere in the horizontal coordinate system. It ranges from 0o for objects located on the horizon, to 90o at the zenith.
