Who named the days of the week

The Greeks named the days week after the sun, the moon and the five known planets, which were in turn named after the Gods Ares, Hermes, Zeus, Aphrodite, and Cronus. The Greeks called they days of the week the Theon Hemerai "Days of the God".

How many types of dog breeds are there in the World.

Now there are 340 breeds recognized by the Federation Cynologoquie international(FCI), the world governing body of dog breeds, sometimes known as the World Canine Organization. But the standards of breed recognition vary from country to country - the American Kennel Club currently recognizes only 167 breeds. 

What colour is the sun?

However, the Sun is essentially all colors mixed together, which appear to our eyes as white. This is easy to see in pictures taken from space. Rainbows are light from the Sun, separated into its colors. Each color in the rainbow (red, orange, yellow, blue, violet) has a different wavelength. When we see the Sun at sunrise or sunset, when it is low in the sky, it may appear yellow, orange, or red. But that is because of only its only short wavelength colors ( green, blue, violet ) are scattered out by Earth's atmosphere, much like small waves are dispersed by big rocks along the shore. Hence the only reds, yellows, and oranges get through the thick atmosphere to our eyes.
