A
small but distinctive constellation between Andromeda and Aries,
consisting of 3 main stars that form a thin delta or triangle shape.
The Greeks referred to it as Deltoton.
Alpha
magnitude 3.4 its a F5 giant star with a temperature of 6,000’C and
lies at a distance of 63 light years.
Beta
magnitude 3.0 is actually brighter than alpha it is an A5 star with a
temperature of 8,000’C and is 127 light years away.
Gamma
magnitude 4.0 is an A1 class star with a temperature of 9,200 ‘C
and is 112 light years away.
Its
most important feature is the spiral galaxy M33 which is the 3rd
largest member of our local system of our local group of galaxies,
following the Andromeda Galaxy and out own Milky Way. M33 has a
magnitude of 5.7 and is around 2.7 million light years away,
slightly further than the Andromeda galaxy. However because M33 lies
face on to us and covers a larger area it is more difficult to see.
