1 Listen and read. Our field trip
Yesterday, my class visited a planetarium. It was great! We learned about our galaxy, the Milky Way, and the different planets in it. Did you know that, thousands of years ago, in the 6th century BCE, a Greek philosopher called Anaximander realised that the Earth was round? Then, later, in the 3rd century BCE, Eratosthenes, a Greek mathematician and astronomer, demonstrated that his theory was correct by observing the shadow of a stick on the ground. But, the Greek philosopher Anaxagoras was recognised for this discovery when he observed the Earth’s shadow after a lunar eclipse. It’s amazing how much ancient people discovered just by observing!
Many centuries later, human beings wanted to know more about the Universe. In 1957, the Russians sent a dog called Laika into space in a satellite called Sputnik 2. She was the first living being in space! Later, in 1961, the Russian pilot and cosmonaut Yuri Gagarin was the first man in space. Then, in 1963, a Russian engineer and cosmonaut called Valentina Tereshkova became the first woman in space. Finally, in 1969, Neil Armstrong, an American engineer and astronaut, was the first person to walk on the Moon. Incredible!
Maybe I will travel to space one day. Nothing is impossible!

2 Galaxies, nebulae and stars
Galaxies are a collection of nebulae and millions of stars.
• Nebulae are huge clouds of gas and dust. Stars come from nebulae.
• Stars are very large, hot balls of gas. They produce light and heat.
Our galaxy, the Milky Way, also has:
satellites planets dwarf planets asteroids comets
The Big Bang was a huge explosion that created the universe billions of years ago.
Nebulae produce stars.

3 Other celestial bodies
• Planets are spherical, rocky and gaseous. They revolve around a star.
• Dwarf planets are also spherical, but they are smaller than planets.
• Satellites revolve around a planet. The Moon is Earth’s satellite.
• Asteroids are rocky objects that travel through space or revolve around a star or a planet.
• Meteorites are asteroids that collide with planets or satellites.
Small meteorites that disintegrate in the Earth’s atmosphere are called shooting stars.
• Comets are balls of dust and ice. They have tails of steam that shine when they get closer to stars. The most famous comet is Halley’s Comet.

A solar system is a star and the celestial bodies that revolve around it.
The star in our Solar System is the Sun. Compared to other stars, the Sun is medium in size. There are much smaller and much bigger stars!
The Sun produces a lot of energy, and provides light and heat to the planets, including the Earth.

There are eight planets in our Solar System. The order of the planets, starting with the one closest to the Sun, is:
Some planets have satellites.
• Jupiter and Saturn have more than sixty satellites each! The satellites are different sizes and have different orbits, the paths they take around the planets.
• The Earth has one satellite - the Moon.
Dwarf planets
Dwarf planets revolve around the Sun, past Neptune’s orbit. The most well-known dwarf planet is Pluto. It was originally considered to be a planet. Other dwarf planets are Ceres and Eris.

7 What is the Earth like?
The Earth is a rocky, spherical body. It is slightly at at the poles. It has three different parts.
• The atmosphere is the layer of air that surrounds the Earth. It is approximately 1 000 km thick.
• The hydrosphere is all the water on the Earth. It covers about 70 % of the surface. That’s why the Earth looks blue from space!
• The geosphere is the solid, rocky, part of the Earth. It has three layers:
– The crust forms the continents and the seabed. The hydrosphere and the atmosphere rest on it.
The mantle is between the crust and the core. It is made up of very hot rocks.
– The core is in the centre of the Earth. It is made up of metals.

Refresh What type of celestial body is the Moon?
9 What is the Moon like?
The Moon is the Earth’s only satellite. It rotates on its axis as it revolves around the Earth. This takes twenty-nine and a half days.
Light
The Moon doesn’t produce light. It re ects light from the Sun. But the Sun only illuminates a certain part of the Moon at a certain time.
So, from the Earth, we see a bigger or smaller part of the Moon each day. These are called the phases of the moon.
Tides
The Moon pulls on Earth's water with a natural force called gravity. This pull creates the tides, the rise and fall of sea level.
Solar eclipses
When the Moon moves between the Sun and the Earth, part of the Sun’s light is blocked, and the sky slowly gets dark. This is called a solar eclipse.

11 How does the Earth move?
The Earth revolves around the Sun. It takes 365 days and six hours (one year) to complete a full revolution.
The Earth also rotates on its axis. It takes 24 hours (one day) to complete a full rotation. Because of this rotation, the Sun illuminates some places of the Earth and leaves others in darkness, causing day and night.

Refresh What are the four seasons?
12
What causes the seasons?
The Earth’s position in relation to the Sun changes during the year. This is because the Earth rotates on a tilted axis. This means that the Sun’s rays reach the Northern Hemisphere at different angles, depending on the time of year.
1
This causes the seasons:
• Summer (June 21st to September 23rd). Days are longer than nights. Temperatures are hot.
• Autumn (September 23rd to December 21st). Days and nights are the same length. Temperatures are mild.
• Winter (December 21st to March 20th). Nights are longer than days. Temperatures are cold.
• Spring (March 20th to June 21st). Days and nights are the same length. Temperatures are mild.
Answer the questions.
a) When is the Earth closer to the Sun? In winter or summer?
b) Why is the temperature different in summer and winter? Make a drawing to explain your answer.
