00:00:00,000 --> 00:00:07,000
Hello, this is astronaut Lucia speaking from the outer space.

2
00:00:07,000 --> 00:00:12,000
Do you want to learn some curiosities of the solar system?

3
00:00:12,000 --> 00:00:14,000
Come with me!

4
00:00:17,000 --> 00:00:24,000
The solar system is part of a galaxy called the Milky Way.

5
00:00:24,000 --> 00:00:30,000
The sun is at the center of the solar system.

6
00:00:30,000 --> 00:00:35,000
The sun is huge, bright and hot.

7
00:00:35,000 --> 00:00:42,000
The eight planets orbit around the sun.

8
00:00:42,000 --> 00:00:55,000
The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

9
00:00:58,000 --> 00:01:03,000
Not all the planets have got the same sizes.

10
00:01:05,000 --> 00:01:11,000
Let's pretend the Earth is a chickpea.

11
00:01:12,000 --> 00:01:25,000
Let's pretend the moon is a sesame seed.

12
00:01:28,000 --> 00:01:34,000
Let's pretend Mercury is another sesame seed.

13
00:01:34,000 --> 00:01:43,000
Venus could be a pea.

14
00:01:43,000 --> 00:01:53,000
Mars could be a corn seed.

15
00:01:53,000 --> 00:01:58,000
Jupiter could be an orange.

16
00:01:59,000 --> 00:02:09,000
Saturn could be a tangerine.

17
00:02:09,000 --> 00:02:17,000
Uranus could be a grape.

18
00:02:17,000 --> 00:02:25,000
Neptune could be a cherry tomato.

19
00:02:26,000 --> 00:02:35,000
And the sun could be a piñata de bolo.

20
00:02:35,000 --> 00:03:00,000
Now we are going to see the two movements of the Earth, rotation and revolution.

21
00:03:00,000 --> 00:03:06,000
Rotation is when the Earth spins on its axis.

22
00:03:06,000 --> 00:03:12,000
It takes 24 hours, one day.

23
00:03:12,000 --> 00:03:16,000
It costs day and night.

24
00:03:16,000 --> 00:03:25,000
Revolution is when the Earth orbits around the sun.

25
00:03:26,000 --> 00:03:38,000
It takes 365 days and 6 hours.

26
00:03:38,000 --> 00:03:48,000
Revolution and tilt causes the seasons, spring, summer, autumn and winter.

27
00:03:49,000 --> 00:03:54,000
Now we are going to see the moon phases.

28
00:03:54,000 --> 00:03:59,000
The moon orbits around the Earth.

29
00:03:59,000 --> 00:04:09,000
It takes 29 days for one complete revolution.

30
00:04:10,000 --> 00:04:22,000
When the moon is here, it's new moon, because the people in this part of the Earth doesn't see the moon.

31
00:04:22,000 --> 00:04:38,000
When the moon is here, it's waxing crescent moon, because the people in this part of the Earth, they only see a D of the moon.

32
00:04:39,000 --> 00:04:53,000
When the moon is here, it's full moon, because the people in this part of the Earth doesn't see all the moon.

33
00:04:54,000 --> 00:05:12,000
When the moon is here, it's waning crescent, because the people in here, they see a C, the letter C.

34
00:05:12,000 --> 00:05:16,000
And that's all. Bye bye!
