March 13 is celebrated as Ear Muff Day. If you live in a cold climate like Chester Greenwood did, and had large, protruding ears, like Chester Greenwood did, you might be thankful for his invention. National Earmuff Day honors the man who found a better way to keep his ears warm all winter long.
After a day of ice skating in the cold, 15-year-old Chester came up with an idea to keep his big ears warm. Partnering with his grandmother who sewed tufts of fur between loops of wire, Chester soon had a working model. Farmington, Maine is now the “Earmuff Capital of the World”

- Uranus is known as the “sideways planet” because it rotates on its side. Uranus’ unique sideways rotation makes for weird seasons. The planet’s north pole experiences 21 years of nighttime in winter, 21 years of daytime in summer and 42 years of day and night in the spring and fall.
- Uranus was the first planet found using a telescope.
- Uranus is an Ice Giant planet and nearly four times larger than Earth.
- Uranus has 27 known moons, most of which are named after literary characters from the works of William Shakespeare and Alexander Pope.
- Like Saturn, Jupiter and Neptune, Uranus is a ringed planet.
- Like Venus, Uranus rotates east to west, the opposite direction as most other planets.
- Uranus is the 7th planet from the sun.
