Because it is bright but more importantly, it is relatively close to Earth -
a mere 8.6 light years from us, which is close in star terms.

What star has the brightest apparent magnitude as seen from earth?
The brightest star as seen from Earth is the sun. The brightest star in the night sky is Sirius.
Is Sirius visible at night in the northern hemisphere during the summer?
No. Sirius is a star that is seen during the winter months in the northern hemisphere.
Is a sirius star bigger than a barnard star?
Yes, Sirius is quite big while Barnard's star is small.
Can you see a white dwarf?
Yes you can see a white dwarf star. but you will need a powerful telescope. The nearest white dwarf to us, is Sirius B at a distance of 8.6 light years. It was first discovered using a 18.5-inch (470 mm) aperture telescope.
What is the brightest star seen from Tobago?
The brightest star in the sky is Sirius. The brightest object that looks like a star is the planet Venus - which is brighter than any star. You can see it these days (Aug. 2010) after sunset in the west, as a very bright star.
What is the brightest star that can be seen from Great Britain?
Sirius is the brightest star and can be seen from the UK. Link: http://en.wikipedia.org/wiki/Sirius ----
What did the astronomers use to discover that the star Sirius was moving away from Earth?
A freaking telescope
Is sirius a star or planet?
The star Sirius is not a planet or even a single star but is in fact a binary star, or two stars that orbit each other. Together, these two stars are often called The Dog Star, as they are the brightest object in the constellation Canis Major - or The Big Dog. The stars, named Sirius A and Sirius B, orbit each other about 20 Astronomical Units (the distance from the Sun to the planet Uranus) that takes about 50 years to complete on orbit. Right now, they appear to be moving away from each other and will reach their maximum separation on the year 2019. At a distance of roughly 8.6 light years, the Sirius binary star system is actually relatively close to us. Sirius A (the larger of the two binary stars) is also extraordinarily bright, about 25 time brighter than our sun. These two factors make Sirius one of the top ten brightest stars in our night sky. While Sirius A is very large and bright, Sirius B (the smaller of the two binary stars) is significantly smaller than it's companion - about the size of our Earth. But even at it's small size, Sirius B still has nearly the same mass as our Sun. That much mass in such a tiny space means more surface gravity (about twice that of Sirius A) and more heat (about 2.5 times that of Sirius A). Just because it's small, doesn't mean it's not awesome. Sirius is considered a wintertime star, usually only seen between the months of December and March. It is part of the Winter Triangle asterism along with Betelgeuse and Procyon. So if you're in the Northern Hemisphere and the weather begins to turn cold, take a look into the southern night sky and find Sirius, The Dog Star!
How can the star Sirius be seen?
Its possible to see Sirus. Its the brightest star you can in the Sky.
Apart from the sun which is the brightest star seen on earth?
The star Sirius is the brightest star visible from the earth. Sirius is in the Canis Major constelation, and is therefore often refered to as "the Dog Star"
What star has the brightest apparent magnitude as seen from earth?
The brightest star as seen from Earth is the sun. The brightest star in the night sky is Sirius.
Which star would be seen as the brightest star?
The Sun, otherwise known as Sol. In at second, Sirius.
How do you find Sirius A in the sky?
Standing in the northern hemisphere facing south and then looking up, Sirius will appear below and to the left of the constellation Orion. It is easy to spot as it is the brightest star in the night sky. Sirius A and Sirius B are both part of the same system and are much too close to each other for us to see the distance between them without a powerful telescope. The vast majority of the Sirius' light comes from Sirius A.
Is Sirius brighter than Polaris?
As seen from Earth, yes, Sirius is the brightest star in the night sky. In terms of actual brightness, no.
Is Sirius visible at night in the northern hemisphere during the summer?
No. Sirius is a star that is seen during the winter months in the northern hemisphere.
What year was sirius found to be double star?
It was deduced mathematically in 1844 by Bessel, but Sirius B was not seen until 1862 by Alvin Clark.
Can Jupiter be seen at night without a telescope?
Yes. It's normally one of the brightest objects in the sky.Easily. It's one of the brightest objects in the night sky. If you can see the star Sirius, anything noticeably brighter than that and not reddish in color is either Jupiter or Venus (or the Moon, but that one's kind of obvious).
