About 8.6 light-years
or
8.6 yrs x 365 days/1 yr=3139 days * 24 hr/1day=75,336 hrs *60 secs/1hr=4520160 secs * c (speed of light 186,000 miles/sec)=84,749,760,000,000 miles from Earth.......(or how much our country with be in debt by 2020 LOL )

Is Sirius brighter than the sun?
Yes it is much bigger.Probably 5 suns can fit in sirius.Not only is sirius bigger but it is much hotter as well.
What is the orbit of sirius?
Sirius is a star therfore is doesnt orbit. Furthermore sirius is to distant for us to obtain such information.
Which star is bigger sirius or rigel?
Rigel is approximately ten times LARGER than Sirius
What is the exosphere distance?
if you are talking about the distance from start to finish, then you can't have an answer because nobody knows. It goes on into space. If you are talking about the distance from the Earth, then it is about 500km...
Let's say that the greatest distance between the earth and the sun during earth's revolution is 152 million kilometers. What is the distance in megameters?
Your 152 million kilometers is 152,000 megameters.
Is Sirius the largest star?
No. Sirius is the brightest star in Earth's night sky, but how bright a star appears is a product of its actual brightness and its distance from us. Sirius itself is actually two stars with Sirius A emitting the vast majority of the system's light. Sirius A is a fairly large star, but others are much larger.
What is the distance from earth to the red arm of the galaxy?
About 2 minutes through a wormhole - you turn left at Betelgeuse and then take a right at Sirius.
Is sirius moving away from or towards earth?
Towards Earth, at 7.6 km/sec. They say that in the future, we might be in "Sirius" trouble - but the fact is that Sirius doesn't move exactly towards Earth; there is also a sideways movement, so Sirius would miss us.
Is Sirius A an Earth-like star?
No. There is no such thing as an "earth-like star" as Earth is a planet, not a star. Sirius A is a star that is larger and brighter than the sun.
Is Sirius A a nearby galaxy?
Sirius is the brightest star in the night sky of earth not a galaxy
Is sirius bigger than earth?
Yes. Sirius actually consists of two stars. The main object, Sirius A is not only bigger than Earth but is almost twice the diameter of the sun. The secondary star, Sirius B is a collapsed remnant of a star called a white dwarf. It is slightly smaller than Earth but far denser.
Where is Sirius b located in the night sky?
Sirius, which consists of both Sirius A and Sirius B is in the constellation Canis Major, which, if you are looking south, appears below and to the left of Orion. Sirius B itself is too dim to be seen from Earth; the vast majority of the light from Sirius is from Sirius A. Even then, as a binary system, the two stars are too close together for us to see them separately.
How far apart are Sirius A and Sirius B?
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).
When was Sirius discovered?
Sirius A and B were never discovered. They have been in the night sky since humanoids first roamed the Earth. Even the dinosaurs would have seen Sirius. So no one, or creature can be said to have "discovered" Sirius.
Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?
Rigel has a greater absolute magnitude than Sirius but apears dimmer from Earth do to the farther distance the light waves must travel through space (just a little more information : ), but there are probably alot more stars around that distance
Why does Sirius appear brighter than Pollux in your nightime sky?
Because Sirius is closer to the earth that's why it is bigger
How long does Sirius take to orbit the sun?
Sirius does not orbit the Sun.
