Question

can any one tell me the name of the star that guides the sailors?

also suggest some synonymns for the word "light"

Thanks in Advance

Answer 1

In the Northern Hemisphere, the North Star, or Polaris
In the Southern Hemisphere, the Southern Cross points toward the South Pole. There is a South Star, but it is not bright enough to be of much use.

light
beam
blink
fire
glare
glitter
gloss
illumination
electromagnetic radiation

Answer 2

A ship's navigator can use ANY celestial object for which he knows the right ascension and the declination. Provided with a sextant, a very accurate clock, and a nautical chart, he can determine a geodedic circle on which his ship must be located. If he measures two celestial objects, he'll narrow his ship's location down to either of two possibilities, namely, the two points where two such circles intersect. With a third celestial object, he can say which of the two points marks the position of his ship.

Doing this properly requires some correction for the navigator's height about sea level (even if it's only a few feet), another correction for atmospheric refraction, and a third correction for parallax for objects that are relatively near Earth.

See Stan's answer, below, for why it is necessary to take a round of celestial elevation measurements at twilight. I'd assumed that the horizon would be visible by moonlight or by where the Milky Way's stars terminated. But I've only studied celestial navigation theoretically and have never practiced as a ship's navigator.

Answer 3

Polaris is almost at the north pole, it's the north star, yada yada. In the Southern hemisphere, the southern cross points to the south, and the south pole can determined as half the distance between the bottom star of the cross and the star Achernar of the Erinadus constellation. The constellation at the south celestial pole is Octans, but it's very faint.

Answer 4

The North Star is a title of the star best suited for navigation northwards. A candidate must be visible from Earth and circumpolar to the north celestial pole. The current one is Polaris. It is the star at the end of the "handle" of the Little Dipper asterism in the constellation

Answer 5

David S' answer above is correct. Navigators can use any of the stars (and planets) listed in the Nautical Almanac for navigation provided they are visible during morning and evening twilight. The pole stars in the north and south are rarely used anymore because these stars are difficult to see during twilight.

In order to navigate by the stars (and planets) with a sextant, it is necessary to do this at a time of day when the horizon is still visible and stars can be seen. This occurs during twilight.

Answer 6

Polaris. It is also known as the North Star or the Pole Star. The general term for a star that sailors follow is lodestar. There are dozens of synonyms and phrases for light. I suggest any good thesaurus or do a search for poetic references.

Answer 7

Its the pole star or north star that can be used for directions by sailors because its position is almost fixed..

Answer 8

polaris, the North Star, I believe, guided sailors. They also used constellations, like the southern cross and Ursa Major.

Synonyms for light: illumination, luminous, radiance, radiant, etc etc

Answer 9

Northern Hemisphere: they use the North Star .... it stays north
Southern Hemisphere, Southern Cross ... it looks like a kite and the tail points to the south

Answer 10

The star that guides the sailors? My guess would be Angelina Jolie.
