What makes Sirius the biggest star in the night?
Sirius isn't the biggest, but it certainly is the brightest. What makes it so is the fact that it is rather a large star AND it's relatively close to us - only 9+/- light years form Earth.
Even though this star has an absolute magnitude greater then that of sirius it looks dimmer from earth since it's 100 times farther away?
The apparent brightness of a star depends mainly on (1) its absolute (i.e., real) brightness, and (2) the square of its distance from us. The absolute magnitude of Sirius is +1.45, while that of Rigel is -6.95, meaning that Rigel is approximately 2,290 times as bright as Sirius. However, Rigel is approximately 100 times as far from us (870 light years versus 8.6 light years), which reduces its brightness relative to Sirius by a factor of over 10,000. This makes Sirius about 4.5 times brighter than Rigel for a difference of 1.62 magnitudes (-1.44 relative magnitude for Sirius versus +0.18 for Rigel).
Constellation near Carina?

Which is known as bright wandering star?
The brightest star that is not the sun is Sirus. Sirus is a 1st magnitude star. Sirus is 8.7 light years away from Earth, which is not to far away(for a star at least). Sirus is obviously not too big but is very bright and close to Earth! Sirus is in the constellation Canis Major, which in English means "Big Dog".

What is the apparent magnitude of ross 248?
6.9, which makes it just a little bit too dim to see with the naked eye. Another viewpoint: According to my sources, the answer is apparent magnitude 12.2. This is one of the closest stars to Earth, but it's very faint because it's only a red dwarf.
