Polaris (α UMi / α Ursae Minoris / Alpha Ursae Minoris) is the brightest star in the constellation Ursa Minor. It is also very close to the north celestial pole, making it the current north pole star. Much more rarely, it is sometimes called Cynosura. "Polaris" comes from Stella Polaris, the Latin form of its common name "Pole Star." The Greek name Cynosura (Κυνόσουρα) means "tail of the dog" and is the source of the English word cynosure. Other names include the "North Star", the ...

Axial tilt is an astronomical term regarding the inclination angle of a planet's rotational axis in relation to its orbital plane. It is also called axial inclination or obliquity. The axial tilt is expressed as the angle made by one half of the planet's axis and one half of a line drawn through the planet's center and perpendicular to the orbital plane, such that its rotation is in the same rotary direction relative to the former ...

In Greek mythology, Cynosura was a nymph (an Oread) on Mount Ida, Crete. According to some legends, she nursed Zeus when he was being hidden from his father, Cronus. In gratitude, Zeus placed her in the stars when she died. So Cynosura is also another name for Polaris star. Category: Nymphs ...

In navigation, a bearing is the angle between the direction to an object and a reference direction. Unless otherwise specified, the reference direction is generally understood to be magnetic North, in which case the term compass bearing is also used. If navigating by gyrocompass, the reference direction is true north. In stellar navigation, the reference direction is that of the North Star, Polaris. Generalising this to two angular dimensions, a bearing is the combination of antenna azimuth and elevation required ...

Beta Ursae Minoris (β UMi / β Ursae Minoris) is the second brightest star in the bowl of the "Little Dipper," the constellation Ursa Minor. It also has the traditional name Kochab. Kochab was the naked-eye star that served as the Earth's North pole star from 1900 BC to 1100 BC, although it was never as close to the pole as Polaris is now. Due to precession of the equinoxes, the previous holder of the ti ...

The Benjamin Franklin class of submarine was an evolutionary development from the James Madison class of fleet ballistic missile submarine. Having quieter machinery and other improvements, they are considered a separate class. Together with the George Washington, the Ethan Allen, the Lafayette, and the James Madison classes, they comprised the "41 for Freedom." The Franklin class submarines were built with the Polaris A-3, and later converted to carry the Poseidon C-3. During the late 1970s and early 1980 ...

The two celestial poles are the imaginary points where the Earth's spin axis intersects the celestial sphere. The sky appears to drift overhead from east to west, completing a full circuit around the sky in 24 (sidereal) hours. This phenomenon is due to the spinning of the Earth on its axis. The Earth's spin axis intersects the celestial sphere at two points. These points are the celestial poles. As the Earth spins, they remain fixed in the sky, and all other points seem to rotate around them. The celestial poles are also the p ...

Image:Kamal.png A kamal is a celestial navigation device that determines latitude. The kamal was used primarily by the Chinese and Arabs in the 18th and 19th century. The kamal consists of a rectangular wooden card about 2 inches by 1 inch, to which a string with several equally spaced knots is attached through a hole in the middle of the card. The kamal is used by placing one end of the string in the teeth while the other end is held away from the body roughly parallel to the ground. The card is then moved along the string, po ...

A Cepheid variable or Cepheid is a member of a particular class of variable stars, notable for a fairly tight correlation between their period of variability and absolute luminosity. The namesake and prototype of these variables is the star Delta Cephei, discovered to be variable by John Goodricke in 1784. Because of this correlation (discovered by Henrietta Swan Leavitt in 1912), a Cepheid variable can be used as a standard candle to determine the distance to its host cluster or galaxy. Since the period-luminosity relat ...

The British became interested in Polaris after the cancellations of the Blue Streak and Skybolt missiles in the 1950s. Under the Nassau agreement that emerged from the 1962 Nassau Conference between Harold Macmillan and John F. Kennedy, the United States would supply Britain with Polaris missiles, launch tubes, and the fire control system. Britain would make the warheads and submarines. In return, America was given certain assurances by Britain regarding the use of the missile. The Po ...
