Distribution. South America, Central America, and in locations of the Caribbean Islands are where you will find this particular species of snake. They can live in desert locations as well as in rainforests. They tend to enjoy areas with a natural cover and high amounts of humidity the most though.
The distance of a light year. How long would it take the space shuttle to go one light-year? The shuttle orbits the Earth at about 5 miles per second (18,000 mph). Light travels at 186,000 miles per second, which is about 37,200 times faster than the shuttle. So the shuttle would need about 37,200 years to go one light-year.
The average distance to Mars is about three times the minimum and would take three times as long. Getting there is only part of the problem, braking and landing will also take a long time! The last NASA flight took 7 months for the trip and 6 months to get into orbit. Read some Edgar Rice Burroughs.
