1 00:00:00,000 --> 00:00:04,000 My name is Álvaro and I'm going to talk about the solar system. 2 00:00:04,000 --> 00:00:20,000 The solar system consists of the sun and all the planets, the satellites, and all the celestial bodies that surround the sun. 3 00:00:20,000 --> 00:00:37,000 The planets are sphere-shaped bodies which surround the Sun in a non-muscular path called an orbit. 4 00:00:37,000 --> 00:00:45,000 There are two types of planets, the inner planets that are Mercury, Venus, Earth and Mars. 5 00:00:45,000 --> 00:00:54,000 There are four planets closest to the Sun. They all have rocky surfaces. 6 00:00:54,000 --> 00:01:01,000 The outer planets are Jupiter, Saturn, Uranus, and Neptune. 7 00:01:01,000 --> 00:01:06,000 These are four planets farther away from the Sun. 8 00:01:06,000 --> 00:01:22,000 They are called gas giants because they are composed mainly of gas and they didn't have rocky surface. 9 00:01:22,000 --> 00:01:44,000 The solar system is composed by the celestial bodies, the comets, the asteroids, and the 10 00:01:44,000 --> 00:01:56,000 The inner planets are the closest planets to the Sun, that are Mercury, Venus, Earth and Mars. 11 00:01:56,000 --> 00:02:05,000 The outer planets are the farthest to the Sun, that are Uranus, Neptune, Jupiter and Saturn. 12 00:02:05,000 --> 00:02:36,620 The eight planets in order are Mercury, Venus, and Comets are the only objects that orbit the planets, and the celestial bodies are the objects that orbit the Sun. 13 00:02:36,620 --> 00:02:45,669 I am going to talk about the Solar System and the Universe. 14 00:02:45,669 --> 00:02:50,669 The solar system consists of the Sun and all the celestial bodies that surround it. 15 00:02:50,669 --> 00:02:56,669 The Sun is at the middle of the solar system and are mostly a star. 16 00:02:56,669 --> 00:03:00,669 Planets are large spherical bodies. 17 00:03:00,669 --> 00:03:05,669 They are classified into groups in the inner planet and outer planet. 18 00:03:05,669 --> 00:03:09,669 Inner planets are the two planets closest to the Sun. 19 00:03:09,669 --> 00:03:11,669 They all have a low surface. 20 00:03:11,669 --> 00:03:17,669 The closest planets to the Sun are Mercury, Venus, Eve, the Earth and Mars. 21 00:03:17,669 --> 00:03:24,669 The other planets are the four planets farthest away from the Sun. 22 00:03:24,669 --> 00:03:27,669 They don't have a far-off surface. 23 00:03:27,669 --> 00:03:31,669 They are also called gas giants because they are composed of gas. 24 00:03:31,669 --> 00:03:40,669 The other planets are Jupiter, Saturn, Uranus and Neptune. 25 00:03:40,669 --> 00:03:47,669 The satellites are smaller bodies that orbit the planets. 26 00:03:47,669 --> 00:03:52,669 Comets are giant balls of ice. 27 00:03:52,669 --> 00:04:02,669 The universe consists of the Earth, of the Sun and everything we can see in the sky. 28 00:04:02,669 --> 00:04:13,669 The stars are afraid of bodies that contain an enormous amount of gas. 29 00:04:13,669 --> 00:04:16,670 They have different properties. 30 00:04:16,670 --> 00:04:25,670 They have colors that can be blue, white, yellow, orange and red, depending on their temperature. 31 00:04:25,670 --> 00:04:34,670 The star bearing size on our Sun is a medium-sized star. 32 00:04:34,670 --> 00:04:40,670 The luminosity is the amount of energy that contains the nucleus of the star. 33 00:04:40,670 --> 00:04:47,670 The brightness is the light of the star that reaches the Earth. 34 00:04:47,670 --> 00:04:53,670 It depends on the luminosity and the distance from the Earth. 35 00:04:53,670 --> 00:04:59,670 Constellations are a group of stars that form a pattern in the sky. 36 00:04:59,670 --> 00:05:05,670 And galaxies are a group of thousands or millions of stars. 37 00:05:05,670 --> 00:05:10,670 Our galaxy is called the Milky Way and is a spiral. 38 00:05:12,670 --> 00:05:16,670 Hello class, I'm going to speak about the solar system. 39 00:05:16,670 --> 00:05:39,170 As you can see, here are the planets, the Sun and the Jupiter belt also. I'm going to speak about the inner planets. Inner planets are the planets that are the most closest to the Sun. 40 00:05:39,170 --> 00:05:59,290 There are Mercury, Venus, the Earth and Mars. They have a rocky surface and now the outer planets. The outer planets are Jupiter, Saturn, Uranus and Neptune. 41 00:05:59,290 --> 00:06:19,509 That they don't have a rocky surface. The moon. The moon is the earth, the earth, celestial, the earth, natural satellite. He has four faces. The new moon, the full moon, the waning moon and the washing moon. 42 00:06:19,509 --> 00:06:30,269 the universe. The universe is all that we can see and we cannot see. We can't see. 43 00:06:30,269 --> 00:06:37,269 Satellites. Satellites are small celestial bodies that orbit the planets. 44 00:06:37,269 --> 00:06:48,269 Dwarf planets. Dwarf planets are small spherical bodies that orbit the Sun. 45 00:06:48,269 --> 00:06:53,839 And now I'm going to speak about the crater in Arizona. 46 00:06:53,839 --> 00:06:58,839 It's the first preserved meteorite crater on Earth. 47 00:06:58,839 --> 00:07:11,839 It was created 50,000 years ago when a 50-meter diameter of a meteorite crashed into the Earth. 48 00:07:11,839 --> 00:07:15,839 Now I'm going to speak about the constellations. 49 00:07:15,839 --> 00:07:32,839 Constellations are a group of stars that forms a pattern on the sky, like you can see here, the Ursa Minor, the Polaris, the Polestar, the Gira and the Cassiopeia. 50 00:07:32,839 --> 00:07:40,839 Galaxies are made up of thousands and millions of stars and rocks. 51 00:07:40,839 --> 00:07:50,839 There are three types of galaxies. The spiral, the elliptical, and the irregular. 52 00:08:00,839 --> 00:08:09,839 The solar system consists of the sun and other celestial bodies that surround it. 53 00:08:10,839 --> 00:08:29,600 There are two types of planets, the inner planets and the outer planets. The inner planets are Mercury, Venus, the Earth and Mars. And the outer planets are Jupiter, Saturn, Uranus and Earth. 54 00:08:29,600 --> 00:08:33,980 The eight planets in order are 55 00:08:33,980 --> 00:08:46,799 Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune. 56 00:08:48,360 --> 00:08:54,820 The satellites are small terrestrial bodies that are homogenized. 57 00:08:54,820 --> 00:09:05,820 The dwarf planets are spherical bodies that orbit the Sun. 58 00:09:05,820 --> 00:09:16,820 The asteroids are small celestial bodies that orbit the Sun. 59 00:09:16,820 --> 00:09:23,820 The comets are giant balls of ice. 60 00:09:23,820 --> 00:09:33,820 The stars are giant spheres of gas and they have different colours depending on the temperature. 61 00:09:33,820 --> 00:09:45,820 Here we have four types of moon. The full moon, the crescent moon, the crescent moon and the new moon. 62 00:09:45,820 --> 00:09:51,820 And I draw Jupiter and Saturn and that's my picture. 63 00:09:51,820 --> 00:10:04,019 Today I'm going to talk about the universe. These are the planets. The planets are large-shaped bodies that orbit the sun. 64 00:10:04,019 --> 00:10:11,019 They are divided into two groups. 65 00:10:11,019 --> 00:10:24,019 The inner planets are the closest planets to the Sun and all have a rocky surface. 66 00:10:24,019 --> 00:10:31,019 The inner planets are Mercury, Venus, the Earth and Mars. 67 00:10:31,019 --> 00:10:44,419 The outer planets are the farthest planets to the Sun, and they are much larger than the inner planets. 68 00:10:44,419 --> 00:10:51,419 They all are made up of gases. 69 00:10:51,419 --> 00:10:57,419 The outer planets are Jupiter, Saturn, Uranus and Neptune. 70 00:10:57,419 --> 00:11:23,919 This is the surface of the Moon. On the 20th of July of 1969, Neil Armstrong was the first man that set his foot on the Moon. 71 00:11:23,919 --> 00:11:39,919 His mission was to experiment and photograph the Moon. 72 00:11:39,919 --> 00:11:46,919 The stars are giant spheres of glasses. 73 00:11:46,919 --> 00:11:50,919 They produce light and heat. 74 00:11:50,919 --> 00:12:12,259 The sun is the nearest star to the earth. It has different properties. The color, the size, the luminosity and the brightness.
