Sirius is a white main sequence star, whereas Betelgeuse is a red supergiant not on the main sequence.
Sirius is the brightest star in the southern sky during winter. It is part of the constellation Canis Major and is known for its luminosity and distinct bluish-white color. Sirius is often referred to as the "Dog Star."
The supernova would be so much brighter that it's hard to compare, at least 10 magnitudes brighter then Sirius. It would probably be about the same brightness as the full moon in the sky.
Some of the SUPER GIANT stars are Sirius,Sun,Rigel,Betelgeuse,and procyon.
No too sure what you mean by "main" stars but the most obvious ones are:- * The Sun * Polaris * Rigel * Betelgeuse * Sirius * Vega * VY Canis Majoris * Antares * Alpha Centauri * Barnard's Star
No. Betelgeuse is in Orion.
Sirius and Betelgeuse are two of the brightest stars in the night sky, with Sirius being the brightest and Betelgeuse being the 9th brightest. Betelgeuse is in the wonderful constellation of Orion. Sirius is in the nearby constellation of Canis Major. They are very easy to spot, with Betelgeuse being at the top left of Orion and Sirius, being below and to the left of Orion, with Orion's Belt acting as a good way of pointing towards it. Comparing the two it is also easy to notice the difference in colour as Betelgeuse is a red supergiant and looks reddish in colour, very different to Sirius.
Sirius will have a greater angle, because it is closer to us.
Sirius, polaris, cygnus, betelgeuse, & rigel
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.
Rigel, Sirius, Betelgeuse, Vega and Polaris
vega,rigel,sirius,and betelgeuse are the most different kind of stars.
The three stars are Sirius, Betelgeuse and Procyon.
About 2 minutes through a wormhole - you turn left at Betelgeuse and then take a right at Sirius.

Arcturus: 37 lyAltair: 16.8 lyBetelgeuse: 640 lySirius: 8.6 lySo Sirius is the closest.
