Our solar system is thought to reach out as far as 50,000 AU, where 1 AU is the Earth to sun distance. This it about the limit of the suns gravitational effect. This gives the solar system a diameter of around 100,000 AU.
It's a dwarf galaxy; the diameter is about 6500 light-years (according to information in the Wikipedia article).
Reported values of the distance of Canopus from our solar system vary. One value that appears in several references is 312 light years. If true, then it takes light from Canopus 312 years to reach earth.
our solar system is on a spiral on one of the milky ways many spirals. we are in the milky way galaxy which is 100 000 light years in diameter and 10 000 light years thick at the centre.
The Milky Way is estimated to be about 2,000 light years thick, but about 100,000 light years long/far... Which i guess you can tell, thats a lot.

The OBSERVABLE Universe has a diameter of about 93 billion light-years. "Observable" means that the light of anything beyond that hasn't had time to reach us, since the time of the Big Bang.
It's a dwarf galaxy; the diameter is about 6500 light-years (according to information in the Wikipedia article).
300 sextillion.
Diameter of our Solar System: 2 light-years. That's if you include the Oort Cloud; many definitions of "Solar System" make it much smaller than that. Diameter of our galaxy: 100,000 light-years.
some 100,000-120,000 light-years in diameter, which contains 100-400 billion stars
1.5 trillion.
The Milky Way galaxy is approximately 100,000 light-years (30 kiloparsecs, 9x1017 km) in diameter, and is considered to be, on average, about 1,000 ly (0.3 kpc) thick .
The Andromeda Galaxy is approximately 220,000 light-years in diameter, which is equivalent to about 1,294,833,160,000,000 miles.
Reported values of the distance of Canopus from our solar system vary. One value that appears in several references is 312 light years. If true, then it takes light from Canopus 312 years to reach earth.
