All living things on Earth are dependent on the sun to stay alive.

All life on Earth needs the sun to thrive and grow. All energy that humans consume originates from the sun, either directly or indirectly.

Plants need sunlight to grow. Humans need plants, or animals that eat plants, to stay alive. Also, electricity is generated by burning oil or coal, which is essentially ancient plants. (Some electricity is created using solar or wind energy, which is also dependent on the sun.) If the sun were to disappear, all plants and animals would eventually die.

The sun is a star.

The sun is a star, but appears to be much larger because it is so close to earth. It is one of the 100 billion stars in the Milky Way galaxy. It is approximately 93 million miles from Earth.

Giant flames, known as prominences, erupt from the sun’s chromosphere. Some of these eruptions are even bigger than the Earth. Very large eruptions are called flares. They are caused by sunspots.

All of the planets in our solar system revolve around the sun.

The Earth, as well as other planets such as Mars, Venus, Saturn, and Jupiter, move around the sun. The length of time it takes a planet to revolve around the sun is referred to as a year. There are 365 days in one Earth year. The length of years vary on other planets.

The four seasons on Earth are determined by how close the Earth is to the sun.

Each year, as the Earth revolves around the sun, the seasons change. It is hottest in the summer when it is closest to the sun. However, it is not always the same seasons on all parts of Earth. Some parts of the Earth are closer to the sun at different times.
