What is the constellation fornax named after?
Most of the "official" star and constellation names were created by the Greek, Roman and Arab astronomers before about 1400. (Much of the Greek and Roman astronomical knowledge was lost during the "Dark Ages", and survived only because of Arabic translations from the earlier texts.) So many star names and constellation names are of Greek, Roman and Arabic origin. Most of the constellations were visible from the latitudes of Greece, Europe and Egypt, and were derived from animals, gods and heroes. Starting in the 1500s and afterward, European seafarers sailing the southern oceans found new stars and new constellations not visible from the northern hemisphere. Many of the constellation names they created were of nautical or technical origin, such as "Telescopium", "Microsopium", "Octans" and "Sextans". The constellation Fornax in the southern hemisphere is named for the Furnace.
One of the stars in the star cluster Pleiades?
Technically this is called an "asterism", and it doesn't have to be a "mythological character", it can be any widely known and recognized pattern. For example, the Plough, the Big Dipper, and Charles' Wain are all asterisms representing a plow, a dipper, and a wagon respectively (they all also happen to be the exact same stars, which are a part of the constellation called Ursa Major, which itself is also the name of an asterism representing a bear). Other non-mythological asterisms include the Summer Triangle, the Southern Cross, the Great Square, Octans (a piece of navigational equipment), and Puppis (the back part of a ship, though admittedly the specific ship in question is from mythology; it's the one Jason - the one who was after the Golden Fleece - sailed).Laypeople (that is, people who aren't astronomers), and even some astronomers when talking to non-astronomers, use the more widely known word "constellation" when what they really mean is "asterism", but technically a constellation is specifically defined patch of sky. All the constellations (there are 88 official constellations, and between them they cover the entire sky) contain the asterism from which they take their name, but they also contain many, many other stars besides, most of which are too faint to see except through a telescope.
What 5 objects can you see in the sky as well stars at various times of the year?
Assuming the Sun is classified as a star. Mercury, Venus, the Moon, Mars, Jupiter, Saturn and on a very good night, Uranus. Oh, that's seven. Take your pick. Not forgetting all the other stuff. Aeroplanes, UFO's :-), comets, meteors, galaxies, space stations, satellites etc.

What southern circumpolar constellation that contains the steller south pole?
Octans (the octant).
South pole is pointing into which constellation?
The earth's south pole points into a big dark patch of sky, completely undistinguished by the presence of anything worth looking at with the naked eye. The nearest constellation is Octans, a triangle of dim stars, the brightest of which has a magnitude of 3.8 (dim). Aside from Octans, there isn't another named constellation, and hardly an easily visible star, within 10 degrees of the celestial pole. (About 20 times the size of the full moon.) Certainly nothing like the North Star to offer the slightest aid to navigation. Pretty disappointing.

Is there a bright south star?
No. Sigma Octans is a star close to the south pole of the sky, but it is not particularly bright.
Is the North star the same as Polaris?
Yes, Polaris in Ursa Minor is the "North Star" located using the stars of the Big Dipper (Ursa Major). It is currently the closest bright star to the celestial pole, i.e. the point directly above the Earth's North Pole. The pole star for the South Pole is currently Sigma Octantis in the constellation Octans.
Southern constellation closest to the sun?
There are many constellations visible in the night sky in the southern hemisphere. What you see will ultimately depend upon your location and the season. Those that are southern circumpolar constellations can be seen all year round. Southern Circumpolar Constellations: Apus, Chamaeleon, Circinus, Crux, Dorado, Hydrus, Mensa, Musca, Norma, Octans, Pavo, Triangulum Australe, Tucana, Volans
What is the story behind octans constellation name?
The sailors who named most of the southern hemisphere constellations looked up and imagined shapes in the stars; and since they were sailors, they imagined nautical objects, like the Octant, the Compass, the Telescope, the Flying Fish, and the Stove.Octans, the Octant, represents a navigational instrument that is one-eighth of a circle. The octant wasn't big enough for detailed navigation, so a bigger instrument that was one-sixth of a circle - the "sextant" - replaced it.
Is there a southern north star?
There is no particularly bright star near the south pole of the sky. A nearby star is Sigma Octans, but it is not as bright a star as Polaris (the North Star).
Where in the sky above Sydney is the south celestial pole?
Well actually, ALL constellations are circumpolar, but we use the word to meanstars and constellations that are close enough to the poles of the sky that theynever get low enough to set below the horizon.Any star that's within (your latitude) degrees of the pole does that.If you're at the north or south pole, every star that's within 90 degrees ofthe celestial pole is 'circumpolar'. That is, whenever it's dark and clear, yousee exactly half of the whole sky, and it's always the same half no matterwhat time it is. Every star in your half of the sky makes a circle around thepoint directly over your head. No star in your sky ever rises or sets, andyou never see any star that's in the other half of the sky.
Is there a south star?
There is no particularly bright star near the sky's south pole. One star that might qualify is Sigma Octans, but that's only a 5.6 magnitude star - in other words, barely visible with the naked eye.
