Yes, easily. Sirius is the brightest star in the night sky.

The brightest star as seen from Earth is the sun. The brightest star in the night sky is Sirius.

As seen from Earth, yes, Sirius is the brightest star in the night sky. In terms of actual brightness, no.

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"

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.

In terms of actually brightness, yes. Sirius is actually brighter than the sun. In terms of brightness as seen from Earth, no.

No. Sirius, which includes both Sirius A and Sirius B is the Dog Star. Sirius was called the Dog Star long before it was known to be a binary system. The vast majority of the light from Sirius actually comes from Sirius A. Sirius B on its own is too dim to be seen from Earth without a telescope.

No - a star as seen from earth is it's apparentbrightness. It's absolute brightness is measured by astronomical instruments. The brightest visible star from earth is Sirius, in the constellation Canis Major. Spica, in Virgo, has a much higher absolute brightness than Sirius, but Sirius is much closer to earth, so it is apparently brighter than Spica.

Sirius, consisting of both Sirius A and Sirius B, is 8.6 light years away from Earth.

Sirius is 8.6 light years from earth

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.

Sirius is the brightest star and can be seen from the UK. Link: ----

The Sun is the brightest star for us. Apart from the Sun, the next brightest star as seen from Earth is Sirius.

The brightest star in the sky, as seen from Earth, is the sun. The brightest star in the night sky is Sirius.

Sirius is 8.6 light years away.

Sirius is a binary star system. The main star is "Sirius A". It's usually just called Sirius. Sirius A has a white dwarf companion called "Sirius B". Sirius B is too faint to be seen without a telescope. So, the closest star to the star we call Sirius, is Sirius B. If you consider that binary system as basically "one star", then the nearest bright star to Sirius is Procyon. There are a few other stars near to Sirius, but they can't be seen with the "naked eye".

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.

Sirius is 8.6 light years from Earth, while Polaris is 434 light years. So yes, Sirius is the closer of the two.

The distance from Earth to Sirius is about sixty trillion miles (or for the astonomically inclined, 8.6 lightyears).

Sirius is the brightest star in the night sky of earth not a galaxy

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.

No, for several reasons. The first and most important is that Sirius B and Sirius A have, as seen from Earth, a minimum angular separation of 3 arcseconds. They never eclipse each other. Also, Sirius B is much smaller than Sirius A, and they're at about the same distance from Earth, It's too small to block more than a miniscule fraction of light from Sirius A. A more accurate description of what would be seen from Earth if it could actually line up with A would be a "transit", not an eclipse. Finally, periastron occured in 1994. The two stars have actually been moving further apart since. Since the period is about 50 years, the next time they're close together won't be for another three decades, and certainly not this year.

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.

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.)

No. Sirius is a star that is seen during the winter months in the northern hemisphere.

Sirius is approximately 8.7 light-years away from Earth.In order to find Sirius in the night sky, find Orion's Belt, and follow its line of stars down to the left and you will find Sirius.
