FUN FACTS
1) Brighter Sun, Darker Earth
In a few billion years, as our Sun nears the red giant phase, it will be about 2.5 times brighter than it is today. The Earth, however, will bedarker because the hotter Sun will boil all the oceans away, clouding the Earth with thick blankets of steam.
2) Valles Marineris
Mars is a small world of giant geological features. It contains the largest can yon in the Solar System, Valles Marineris, 2800 miles (4,500km) long. If this giant canyon was super imposed to scale on a map of North America, it would stretch from New York to California!
3) Driving to the Stars
Alpha Centauri is the nearest star system to Earth, 4.3 light years away, but you wouldn't want to drive there. If you had a cosmic car with an unending fuel supply, driving at 55 miles per hour it would still take 52 million years to reach the star!
