The Universe

1. The Sun

   • The Sun is the largest object in our solar system. It is so large that 1.3 million Earths could fit inside it! The Sun is also the brightest star in our sky. Many people don’t think of the Sun as a star because it looks larger and brighter than the stars we see at night
     • This light, however, must travel a very long distance before it reaches our planet. Sunlight travels 93 million miles in only eight minutes to get to Earth! Light from the next closest star to Earth, Alpha Centauri, travels for four years before we can see it.

2. A Constellation

   • is a group of stars that, when seen from Earth, form a pattern or a shape. These groups of stars appear to form pictures in the night sky. There are many constellations, and each one of them resembles a picture imagined by somebody in the world.
     • Orion is one of the most recognized constellations. This constellation resembles the shape of a hunter, and it can be seen from different places throughout the world at different times of the year.

3. The Planets

   • Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune
     • These planets are known as the “gas giants” because they are all gigantic compared to Earth, and they are made up mostly of gas. Some of them also have a small center made out of rock. These gas giants are located very far from the Sun and from one another

4. A galaxy

   • is a group of stars, planets, dust, and gas. Galaxies are found all over the universe, and they have different sizes and shapes. Scientists group galaxies according to their shape. An irregular galaxy does not have a clear shape and is full of young stars, dust, and gas.
     • A spiral galaxy is shaped like a disk with curved arms. These galaxies tend to have older stars. Elliptical galaxies look like round or fattened circles.

5. The planet Earth

   • The planet Earth may seem like a pretty big place. However, it is actually a very small part of the universe. Earth is the third planet from the Sun, and it is the only planet in our Solar System that has life. Most of Earth’s surface is covered by water
     • The atmosphere also makes it possible for plants, animals, and people to live on the planet.Under the surface, Earth has a layer of hot rock and two layers of metals in solid and liquid form. Earth has one natural satellite that moves around it: the Moon.
