Facts and Info
The information that I am about to share with you is merely a sample of some of the wonders of the Universe. Many more facts, including detailed information on each planet in the solar system can be found in the book George's Secret Key To The Universe.
Light and Stars
- Everything in our Universe takes time to travel, even light.
- In space, light always travels at the maximum speed that is possible: 186,000 miles per second (300,000 km per second). This speed is called the speed of light.
- Our Sun is further away from us than our Moon is.
- When light leaves the Sun, it takes about 8 minutes and 30 seconds to reach us on Earth.
- Distances in space can be measured in terms of light-years, which is the distance light travels in one year. A light-year is almost 6,000 billion miles (around 9,500 billion km).
