Pleiades (M45) Facts Open Star Cluster in Taurus

Pleiades (M45) is an open star cluster object of interest in space. It lies at a distance of between 390.00 and 460.00 light years away in the constellation of Taurus.

It is referred to as M(45) when it was catalogued by Charles Messier in 18th - 19th Century France.

The Open Star Cluster's location is 03:47.0 (R.A.) and +24:07 (Dec.). Its Visual (Apparent) Brightness is 2.00 Magnitude with an apparent dimension of 111.0 . The object can be seen with the naked eye from Earth, that is, you don't need a telescope/binoculars to see it.

The Pleiades are a star cluster that can be found in the constellation of Taurus. They are one of the most well known star clusters that we know about. Another star cluster also in the constellation of Taurus is the Hyades. It is naked eye visible, although you won't probably be able to see it clearly. It was first observed by the Grecian astronomer Hesiod 1000 Years B.C.

The Pleiades are said to be the seven daughters of the Greek God, Atlas who were transformed into stars to comfort him as he held up the stars and galaxies in place within the Universe. The seven daughters are in no particular order, Asterope, Taygeta, Maia, Celaeno, Electra, Alcyone, Merope. Pleione and is the mother of the Seven Sisters.

They are amongst the youngest stars in the galaxy. If you travelled back into the past to the time of the dinosaurs and Prehistoric Animals, you wouldn't see them because they weren't created back then.

When best to view the Pleiades

The Pleiades are visible without any visual aids but to make them out, you will need to use some form of visual aids such binoculars or a telescope. The easiest way to find them is to locate Orion which is the easiest constellation to spot in the night sky.

Northern Hemisphere

In the Northern Hemisphere, the constellation is best seen in the winter months when Taurus appears high in the sky in January and Februrary. As mentioned earlier, find Orion then look upwards in a southerly direction, you shoud then see Taurus. Look for a fuzzy area of stars and that should be the pleiades.

Southern Hemisphere

The first three months of the year and December should be the best time in which to see the Pleiades. Taurus is in a northerly direction and is low on the horizon. The more north in the southern hemisphere, the better to see them.

Travel Time to Pleiades (M45)

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
