11. THE SOLAR SYSTEM INNER PLANETS OUTER PLANETS ROCKY GAS GIANTS
12. The Sun • A massive nuclear fireball, that provides all of the heat and light we get on Earth. • The Sun is a normal star, in a normal part of the galaxy. • Every star you can see in the night sky is a star, like the Sun. Day Planets Dwarf Planets Mass 25-35 days 8 5+ 330,000 x Earth
13. The Sun • A massive nuclear fireball, that provides all of the heat and light we get on Earth. • The Sun is a normal star, in a normal part of the galaxy. • Every star you can see in the night sky is a star, like the Sun. Day Planets Dwarf Planets Mass 25-35 days 8 5+ 330,000 x Earth
17. Mercury • Smallest planet • Very hot in the day, very cold at night • Looks a bit like the Moon • Stars can be seen in the day because there is no air on Mercury Day Year Moons Mass 59 days 88 days None 0.06 x Earth
18. Venus • The hottest planet • Sometimes called Earth’s twin because of its size • Covered in a thick layer of acid clouds • A Venus day is longer than a Venus year! Day Year Moons Mass 243 days 226 days None 0.82 x Earth
19. Venus • The hottest planet • Sometimes called Earth’s twin because of its size • Covered in a thick layer of acid clouds • A Venus day is longer than a Venus year! Day Year Moons Mass 243 days 226 days None 0.82 x Earth
20. Earth • Only known planet with life • 10% of the Earth is covered in ice • Like most planets the Earth is not actually round - it more like a slightly squashed ball! Day Year Moons Mass 24 hours 1 year 1 1 x Earth
21. Mars • Biggest volcano in the Solar System is Olympus Mons. It is 15 miles high! • Its moons, Phobos and Deimos are not round, but rocky. • Called the red planet because it actually looks red in the night sky! Day Year Moons Mass 24 hrs 43 mins 1.88 years 2 0.11 x Earth
27. Jupiter • Has a great red spot, which is really a massive hurricane. • Jupiter has a faint ring • So big you could fit 1,300 Earths inside it! • Very bright and visible in the evening right now. Day Year Moons Mass 9.5 hours 11.9 years 63 318 x Earth
28. Saturn • The rings are made up of bits of rock and ice. • Its biggest moon, Titan, is larger than the planet Mercury. • There are small moons within the rings. Day Year Moons Mass 10.5 hours 29.5 years 61 95 x Earth
29. Uranus • Orbits the Sun on its side - meaning that night can last for 40 years. • Has no features on the surface - make sit look boring. • It is the coldest planet in the Solar System. Day Year Moons Mass 17 hours 84 years 27 15 x Earth
30. Neptune • Farthest planet, and the stormiest. Hurricane son Neptune are 5x more powerful than on Earth. • Neptune and Uranus both have rocky cores deep inside them. Day Year Moons Mass 16 hours 165 years 13 17 x Earth
31. MERCURY VENUS EARTH MARS JUPITER SATURN URANUS NEPTUNE THE SOLAR SYSTEM
32. The Moon • Man first landed on the Moon in July, 1969. Over 40 years ago! • There is no air on the Moon. No wind or weather. This means that the astronauts footprints will last for thousands of years. • The Moon orbits the Earth in just over 27 days. • How long would it take to get there in a car?
34. “One small step for man. One giant leap for mankind” Neil Armstrong, July 20th 1969
35. International Space Station
38. • The ISS orbits the Earth every 90 minutes • The first parts were put into space in 1998. • Since 2000 there has always been someone aboard the ISS - the crew changes every 6 months. • You can see the ISS fly overhead!
39. Tarantula Nebula
40. Rosette Nebula
41. Comet Hale-Bopp
42. Comet Hale-Bopp • Comets actually have two tails. • One is a trail of stuff left behind as it flies along. • The other is caused by the Sun boiling material off the comet’s surface. • You can often see comets in the night sky.
43. Comet Hale-Bopp and the Milky Way
45. 100,000 light years The Milky Way
46. 100,000 light years The Milky Way Black  Hole
48. • Black holes are so dense that even light cannot escape - that is why they are black. • There are 14 known black holes - but there must be many many more. • Black holes are only seen when they suck material off other objects - like stars. • The closest black hole to Earth, Cygnus X-1, is 8,000 light years away.
