I received these cool pics in an email. I thought they were interesting and was curious about some of the stars I’d never heard of. This lead to a round of Googling…

Asteroids The vast majority of asteroids are grouped in the asteroid belt, which is more like a loose grouping than a belt, and lies between 1.8 and 4.5 A.U. (1 A.U. is the average distance between Earth and the sun) from the sun – between the orbits of Mars and Jupiter. Asteroids are made of rock and metal. Comets |
One light year is approximately 5.8 trillion miles (5,878,482,164,161 miles) or 525,600 light minutes. One light minute is about 11181134.65 miles.
Depending upon the definition the diameter of our solar system is between 78 AU and 100,000 AU or between 6,510,000,000 (6.51 billion) miles and 9,300,000,000,000 (9.3 trillion) miles. That’s quite a difference of opinion guys. Now that they have “planet” properly defined maybe they’ll tackle “solar system”!.
The Sun’s diameter is 864,938 miles (1,391,980 km). This is almost 10 times larger than the planet Jupiter and about 109 times as big as the Earth. The volume of the Sun is 1,299,400 times bigger than the volume of the Earth; about 1,300,000 Earths could fit inside the Sun
The star Sirius, is the brightest star in our night sky. Distance from Sun: 8 1/2 light-years http://www.siriusrising.com/sirius.htm
The star Pollux is about 33 light years from Sol. http://www.solstation.com/stars2/pollux.htm
Arcturus is 37 light years away.
If Antares were in place of our Sun, it would slightly more than encompass the orbit of Jupiter. It’s about 600 light years from us.
