What is the brigthest star called?

Answer 1

The brightest star in our night sky is the star Sirius. It has an apparent magnitude of -1.46 or so. The meaning of that number is not easy to explain but to put it in context, the sun is a -26 or so (much brighter of course), and Venus can be up to -4.6. So negative numbers are brighter in this case. The star Vega is 0. The dimmest star you can see under perfect conditions is around +6.

Answer 2

The brightest star in the night sky is star called Sirius. It is also known as the dog star, and it is in the constellation called Sirius. It is interesting to note that in Harry Potter, by J.K. Rowling, the character Sirius transforms into a dog. Sirius has a magnitude of -1.4. actually, Sirius is a double star. This means that, while it looks like one, it is two. The first has the -1.4 magnitude. the other is a white dwarf, and much fainter. It emits a lot of X-rays.

Answer 3

What looks like the brightest star is actually a planet - planet Venus. Now (December 2010) you can see it in the morning, to the east, if you wake up before sunrise. The next-brightest "star" is usually planet Jupiter, although sometimes planet Mars is brighter.

The brightest "fixed star" (star proper) is Sirius (Alpha Canis Majoris).

Answer 4

Sirius. This refers to apparent brightness, as seen from Earth. Planets look like stars; if you include those, the answer is "Venus", which looks much brighter than Sirius. (These days - September 2010 - you can see Venus in the evenings, after sunset.)

Answer 5

The largest Hyper Giant known at this moment is VY Canis Majoris

its size would stretch out to Saturn. The hottest or brightest would be one of a few stars the Hyper Giant P Cygni although not as large as Canis with only about 50 times the mass of our sun but is many tens of thousands of times more luminous therefore also hotter.

Answer 6

Sirius is the brightest star in the night sky.

Answer 7

The hottest star is called a blue hypergiant and the brightest star is called a red giant.

Answer 8
