The constellation Ursa Minor contains the star Polaris, which is the pole star.
Two stars in Ursa Major, Merak and Dubhe, form a pair line that points to Polaris. They are the stars on the edge of the "Big Dipper."
The baseline that runs from any point on the Earth's surface to the North Pole is known as a meridian. Meridians are imaginary lines that connect the North Pole and South Pole, running vertically from the equator. They are used in geographic coordinate systems to help determine longitude and location on the Earth's surface.
There is no known constellation named "Chimera" in astronomy. The term "chimera" is often used to describe a mythical creature that lacks a specific representation in the sky as a recognized constellation.
The constellations that are commonly used for navigation to determine direction include the Big Dipper (part of Ursa Major), the North Star (Polaris), and Orion. These constellations are visible in the night sky and can help to determine north or south, east or west.
A compass is a tool often used to determine directions. It works by pointing towards the Earth's magnetic North pole, providing a reference for North, South, East, and West.
The North Star is a star named Polaris, in the constellation of Ursa Minor. It sits, entirely coincidentally, almost precisely above the North Pole of the Earth, and so it is very useful for navigation. Polaris is actually a pretty dim star; it is the dimmest of the stars generally used for navigation, solely because of its position in the sky. Metaphorically, the phrase "north star" is often used to denote a constant point of reference.
The North Star, also known as Polaris, is commonly used for navigation to determine the direction of due north in the Northern Hemisphere. It remains almost stationary in the night sky and can be found by locating the Little Dipper constellation.
Ursa Major is the constellation. The 2 stars in the bowl of the dipper point to Polaris. Polaris IS the North Star.
Ursa Major, The Great Bear, contains the Big Dipper, which is used to find north.

A constellation near the North Star, also known as Polaris, is Ursa Minor, commonly referred to as the Little Dipper. Polaris is located at the end of the handle of this constellation. Another nearby constellation is Ursa Major, which contains the Big Dipper asterism, often used for navigation to locate Polaris. Both constellations are prominent in the northern sky.
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.
The constellation of seven stars that helps to find the points of the compass is known as the Big Dipper, part of Ursa Major. Its distinctive shape resembles a ladle or dipper and can be used to locate Polaris, the North Star, which indicates true north. By following the line formed by the two stars at the end of the "dipper," one can easily find Polaris and determine direction.
Currently, the Earth's south pole is pointing towards the constellation of Octans. This constellation is not very well-known, but it is used for celestial navigation as it helps determine the location of the south celestial pole.
While the Leo constellation itself is not commonly used for navigation, it can be used to find the North Star (Polaris) by tracing an imaginary line through the stars that form the Lion's back. This can help orient stargazers and navigators in the night sky.
