The Solar System for Grades 3-8

  1. 1. The Solar System!
  2. 2. How can you remember the order of the planets?
  3. 3. • • • • • • • • • My Very Excited Mom Just Sold Us Nine Pizzas • • • • • • • • • Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto
  4. 4. Some fast facts about the planets…
  5. 5. • Mercury is the planet nearest to the sun it has no moons. • If you weigh 100 pounds on Earth, you would only weigh 37 pounds on Mercury. • It takes less than 88 Earth days for Mercury to orbit around the sun. • 1 day lasts about 180 Earth days. • The temperature rises above 800°F while on the dark side it falls rapidly to -300°F. Mercury
  6. 6. • Venus, Second Planet from the Sun, Brightest Planet in Solar System • Venus is known as Earths' twin sister because of its similar size and proximity to each other. • Venus has a longer day than year. • It takes 243 days for Venus to make a rotation. • And it takes 224 days for Venus to orbit around the sun. Venus
  7. 7. • The Earth is estimated to be 4.5 billion years old. • It travels through space at 660,000 miles per hour. • The Earth weighs 6,588,000,000,000,000,000,000,000 tons. • The world is not round. It is an oblate spheroid, flattened at the poles and bulging at the equator. Earth (Our Home)
  8. 8. • Mars is the fourth closest planet to the sun. It can easily be seen from Earth Mars • Mars is red because it is rusty. There is a lot of iron in the soil, and the air on Mars has made it turn red. • Mars orbits the sun every 687 Earth days. • The Martian “day” is about half a hour longer than Earth. • In winter, nighttime temps can • A hundred pound man would drop as low as -191°F weight 38 pounds on Mars.
  9. 9. • Jupiter is the largest planet in our Solar System. Jupiter • Jupiter's volume is large enough to contain 1,300 planets the size of Earth. • Jupiter rotates faster than any planet in the Solar System. It rotates so quickly that the days are only 10 hours long... • But it takes 12 Earth years for Jupiter to complete an orbit around the sun. • If you weigh 100 pounds on Earth, you would weigh 264 pounds on Jupiter. The great red spot on is a storm that has been going on for over 300 yrs.
  10. 10. • Saturn is the second largest planet. Only Jupiter is larger. Saturn has seven thin, flat rings around it • The planet can be seen from Earth with the unaided eye, but its rings cannot. • It is so light that it could actually float on water if there was an ocean big enough to hold it. • It takes about 29.46 Earth years for Saturn to orbit around our sun. • Saturn's rings are made up of billions of pieces of rocks and dust. • Saturn is a giant ball of gas, but it does have a solid inner core. • A 100 pound object on Earth would weight 116 pounds on Saturn Saturn
  11. 11. • Uranus is the seventh planet from the sun. • Because of the strange way it spins, nights on some parts of Uranus can last for more than 40 years. • The planet's most extraordinary feature is the tilt of its rotational axis, which is almost perpendicular to the plane of the eclipitc, which means that it alternately has its north pole and its south pole turned towards the sun. • Uranus is the coldest planet in the solar system. • Uranus and Neptune are both known as Ice Giants. • It takes 30,685 Earth days for Uranus to complete an orbit around the sun Uranus
  12. 12. • Neptune is so far away that it took the space probe Voyager 2, 12 years to reach it. • Neptune is the stormiest planet. The winds there can blow up to 1,240 miles per hour, that is three times as fast as Earth's Hurricanes. • Neptune is a sea blue color due to the methane gas in its atmosphere. • Neptune has 8 known moons. • Neptune is 30 times farther from the sun as is the Earth. • It goes around the sun once every Neptune
  13. 13. • Pluto is technically no longer a planet, but it is still the 10th largest body orbiting around the sun. • Pluto is smaller than the Earth's moon. • Pluto has an enormous moon for its size, Charon. It is more than half the size of Pluto. • One reason why Pluto is declassified as a planet is because asteroids has been detected in our solar system that are as large or larger than Pluto. • Technically, Pluto's name is now 134340 after being declassified as a planet. Pluto
