Celestial navigation Celestial navigation Celestial navigation, also known as astronavigation, is the ancient and modern practice of position fixing that enables a navigator to transition through a space without having to rely on estimated calculations, or dead reckoning, to know their position. Celestial navigation uses "sights", or angular measurements taken between a celestial body (e.g. the Sun, the Moon, a planet, or a star) and the visible horizon. The Sun is most commonly used, but navigators can also use the Moon, a planet, Polaris, or one of 57 other navigational stars whose coordinates are tabulated in the nautical almanac and air almanacs.
Luna Park Sydney opened year-round. Luna Park was closed in mid-1979, immediately following the Ghost Train fire, which killed six children and one adult. Most of the park was demolished, and a new amusement park was constructed; this originally operated under the name of Harbourside Amusement Park before resuming the Luna Park name. The park was closed again in 1988 as an independent engineering inspection determined that several rides needed urgent repair. The owners failed to repair and reopen the park before a New South Wales government deadline, and ownership was passed to a new body. Reopening in 1995, Luna Park closed again
