Chapter 1: The Earth in the Solar System
The Earth: Our Habitat
The Solar System
The Sun, the eight planets and their moons, and smaller objects such as dwarf planets, comets, and meteoroids together make up our solar system.
The Sun
The Sun is the hottest and the largest body in our Solar system. It is made of extremely hot gases, but we don't feel its heat too strongly because it is a 150 million kilometres away from us.
It is the ultimate source of light and energy all across our solar system.
The Sun is at the centre of the solar system, and it is so big that it pulls everything in the solar system together; all the planets, moons, and everything in the solar system ultimately revolves around (circles) the Sun.
The Planets
We know of 8 planets in our solar system: Mercury Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. (You can remember their order with the sentence: My Very Educated Mother Just Serves Us Nuts)
All the planets revolve around the Sun on paths called orbits, and the closer a planet is to the Sun, the smaller its orbit is. So Mercury takes only 88 days to circle around the Sun, but Earth takes 365 days.
Pluto was earlier considered the ninth planet, but is now considered a dwarf planet because it's not big enough to be called a planet and has uncleared derbies around it.
The Earth
The Earth is the fifth-largest planet in the solar system, and it is the third planet from the Sun.
The Earth isn't a perfect sphere (ball-like shape), but it is slightly flattened at the top and the bottom (at the north and south poles). This shape is called geoid.
Earth is unique, because it is the only planet in our solar system where we believe there is life. This is because the Earth has conditions favourable to life; it has water, moderate (not too hot, not too cold) climates, and air full of gases such as oxygen, nitrogen and carbon dioxide which are needed by plants and animals.
More than 70% of the Earth is covered in Water. So when we see it from outer space, the Earth appears to be blue and people call it the Blue Planet.
The Moon
The Moon is the Earth's only natural satellite, and it revolves around the Earth once every 27 days or so.
Although the moon is smaller than the Earth, it is still quite big. But we see it as small because it is about 3,84,400 kilometres away from us.
The moon has many mountains and valleys, and they cast shadows on the Moon which look like dark spots when seen from the Earth. But it doesn't have free-flowing water or air, so there is no life on the Moon.
Asteroids
Asteroids are small objects that also circle the Sun.
They are found between the orbits of Mars and Jupiter, and scientists believe they're pieces of a planet that exploded many years ago.
Meteoroids
Meteoroids also circle the Sun, but they are much smaller than comets.
Sometimes they come close to and start falling towards Earth. But they are at such high speeds that when they enter the atmosphere of the Earth, there is friction and they begin to burn; we then see them as a meteor shower, or 'falling stars'.
Sometimes, a meteor doesn't get burnt up before it reaches the land. Instead, it crashes on Earth and creates a crater (a big hole).
