Just for fun... *28% of Africa is wilderness. 38% of the United States is wilderness!! Check out the hiking sites. You might find yourself in places no one else has ever been before. *How many years does it take for Pluto to circle the Sun just once? 248 Earth years. Pluto's distance from the Sun is about 40 times great than Earth's distance. *Boy, do I dislike snakes! Did you know, about 150 people will be bitten this year in Arizona by rattlesnakes? They usually come out just after the sun goes down in the summer. *Do all rattlesnakes rattle before they strike? NO... and they can hold a strike pose for up to 30 minutes without making any sound at all! *Name three significant discoveries at Lowell Observatory in Flagstaff, Arizona. a)19121917: Evidence for an expanding universe discovered b)1930: Clyde Tombaugh, succeeded in discovering the planet Pluto. ("Percival Lowell is perhaps as famous for his commitment to the existence of Planet X as he is for his belief in life and canals on Mars. Lowell himself failed to discover or deduce from mathematical equations the existence of a Planet X. However, one of his apprentices, Clyde Tombaugh, succeeded in discovering the planet Pluto. Using the observatorys blink comparator to examine plates from observations of the constellation Gemini made on January 23 and 29, Tombaugh detected an object flashing in and out of the background. Tombaugh spent three weeks relocating the object in a telescope, tracking it, and photographing it to confirm his discovery. Fittingly, the announcement was made on the anniversary of Percival Lowells 75th birthday, March 13. Pluto actually was named by an 11-year-old English schoolgirl. Lowell Observatory supported the name and submitted it as the official name for the newly discovered planet. Notice, too, the first two letters of the planets name are Percival Lowells initials. The primary reason for proposing this name was to continue the tradition of naming planets after Roman gods. Pluto is the god of the underworld, so it is fitting to name the planet located at the farthest reaches of the solar system after him. c)1977: Astronomers discover rings around Uranus
