2. 0:10many things I like more than sitting
3. 0:12outside on a clear night looking at the
4. 0:15moon in the sky above your planet earth
5. 0:18does present us with some beautiful
6. 0:20sights doesn't it would you like to know
7. 0:25more about the moon follow me most of
8. 0:29the planets in our solar system have
9. 0:31moons or natural satellites as
10. 0:33astronomers call them some planets have
11. 0:36several of them like Jupiter that has 79
12. 0:40that's a lot of moons but the earth only
13. 0:44has one and it's very special not to
14. 0:48mention beautiful
15. 0:50he's showing so brightly because it
16. 0:53reflects the light coming from the Sun
17. 0:55the moon orbits the earth which is the
18. 0:58same as saying it goes around it at the
19. 1:01same time it spins together the moon and
20. 1:05Earth orbit the Sun the moon is about
21. 1:10380,000 kilometers away from Earth and
22. 1:13it's almost spherical shaped like a ball
23. 1:17but it doesn't always look like a ball
24. 1:20in the sky does it that's because of the
25. 1:23phases of the Moon come with me so I can
26. 1:26show you how it works it takes the moon
27. 1:29about a month to go around the earth the
28. 1:32different shapes or phases appear as the
29. 1:35moon goes around the earth and is
30. 1:37illuminated differently by the Sun let's
31. 1:40see how it looks from the northern
32. 1:42hemisphere of our planet when the moon
33. 1:46is in the same direction as the Sun it
34. 1:48can't be seen at night this first phase
35. 1:51is called the new moon seven days later
36. 1:54when the moon is a quarter way through
37. 1:56its orbit half of the illuminated part
38. 1:59of the Moon is seen from Earth this
39. 2:01phase is called the first quarter it
40. 2:04looks just like a capital D doesn't it
41. 2:08halfway through its orbit around the
42. 2:10earth fourteen days after we started
43. 2:13counting we see the full moon as you
44. 2:17might have guessed by now this is my
45. 2:19favorite phase of the Moon when we can
46. 2:21see it in all its glory look at that
47. 2:27when we reach 21 days with
48. 2:31three-quarters of the way around and we
49. 2:33see the last quarter moon now it looks
50. 2:36like a D but backwards if you on the
51. 2:40southern hemisphere you see the moon
52. 2:42reversed and the moon phases look a bit
53. 2:45different it's like looking at the moon
54. 2:47with your head upside down after a full
55. 2:50orbit around the Earth the moon is back
56. 2:52in its starting position and we start
57. 2:55all over again
58. 2:56so the moon is always there but we just
59. 3:00can't see it all of the time
60. 3:02once here another cool thing about the
61. 3:05moon the moon's orbit is tilted this
62. 3:08means that the moon the earth and the
63. 3:11Sun are not always perfectly aligned but
64. 3:14when they are something amazing happens
65. 3:17and eclipse eclipses are magical
66. 3:21experiences the moon can block the Sun
67. 3:25completely from view and make it seem to
68. 3:28disappear from the sky this is called a
69. 3:31total solar eclipse there is also
70. 3:33another type of eclipse the lunar
71. 3:36eclipse now the earth is between the Sun
72. 3:39and the moon the earth blocks nearly all
73. 3:41the sunlight the Sun still reaches the
74. 3:44moon and makes it look beautifully red
75. 3:48[Music]
76. 3:50next time you go outside look up at your
77. 3:53beautiful moon what do you think awaits
78. 3:56us there
79. 3:57join me for our next space adventure to
80. 3:59find out so today we learned that the
81. 4:04moon is the Earth's natural satellite
82. 4:07the moon spins while also orbiting the
83. 4:10Earth together they orbit the Sun it
84. 4:15takes about one month for the moon to go
85. 4:17around the earth the mirror has
86. 4:20different phases and we see it
87. 4:22differently throughout a month when the
88. 4:26moon earth and Sun are aligned we can
89. 4:29have lunar and solar eclipses
