ESA - Space for Kids - Our Universe - The Milky Way

# data[].attributes.attachment_link.description
We live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.

Moon Facts for Kids

Check out these fun Moon facts for kids. Learn how big the Moon is, who the first person to walk on it was, why we only see one side of it and much more. Read on and enjoy the wide range of interesting facts about the Earth's Moon.

The Moon is the Earth's only natural satellite. A natural satellite is a space body that orbits a planet, a planet like object or an asteroid.

It is the fifth largest moon in the Solar System. Learn more about the other moons in the Solar System.

The average distance from the Moon to the Earth is 384403 kilometres (238857 miles).

The Moon orbits the Earth every 27.3 days.

Mons Huygens is the tallest mountain on the Moon, it is 4700 metres tall, just over half the height of Mt Everest (8848m).

The Moon rotates on its axis in around the same length of time it takes to orbit the Earth. This means that from Earth we only ever see around 60% of its surface (50% at any one time).

The side that we can see from Earth is called the near side while the other side is called the far side (it is sometimes called the dark side despite the fact that it illuminated by the Sun just as much as the near side).

The effect of gravity is only about one fifth (17%) as strong on the surface of the Moon compared to the strength of gravity on the surface of the Earth.

The Soviet Union's Luna program featured the first successful landing of an unmanned spacecraft on the surface of the Moon in 1966.

The USA's NASA Apollo 11 mission in 1969 was the first manned Moon landing.

The first person to set foot on the Moon was Neil Armstrong.

The far side of the Moon looks quite different due to its lack of maria (ancient pools of solidified lava).

The surface of the Moon features a huge number of impact craters from comets and asteroids that have collided with the surface over time. Because the Moon lacks an atmosphere or weather these craters remain well preserved.

Although research is continuing, most scientists agree that the Moon features small amounts of water.

The Moon is very hot during the day but very cold at night. The average surface temperature of the Moon is 107 degrees Celsius during the day and -153 degrees Celsius at night.

The Earth's tides are largely caused by the gravitational pull of the Moon.

The phases of the Moon are: New Moon, Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Crescent, New Moon....

A lunar eclipse occurs when the Earth is between the Sun and the Moon.

Sun Facts for Kids

Enjoy these fun Sun facts for kids. Learn how hot the Sun is, how long it takes light from the Sun to reach Earth, what the Sun is made of and more.

Read on for a range of interesting facts about the Sun.

The Sun is a star found at the center of the Solar System.

It makes up around 99.86% of the Solar System's mass.

At around 1,392,000 kilometres (865,000 miles) wide, the Sun's diameter is about 110 times wider than Earth's.

Around 74% of the Sun's mass is made up of hydrogen. Helium makes up around 24% while heavier elements such as oxygen, carbon, iron and neon make up the remaining percentage.

Light from the Sun reaches Earth in around 8 minutes.

The Sun's surface temperature is around 5500 degrees Celsius (9941 degrees Fahrenheit), so pack plenty of sunscreen if you plan on visiting (remembering that the average distance from the Sun to the Earth is around 150 million kilometers).

The Sun's core is around 13600000 degrees Celsius!

The Sun generates huge amounts of energy by combining hydrogen nuclei into helium. This process is called nuclear fusion.

Because of the Sun's huge influence on Earth, many early cultures saw the Sun as a deity or god. For example, Ancient Egyptians had a sun god called Ra while in Aztec mythology there is a sun god named Tonatiuh.

The Sun produces a solar wind which contains charged particles such as electrons and protons. They escape the Sun's intense gravity because of their high kinetic energy and the high temperature of the Sun's corona (a type of plasma atmosphere that extends into space).

Planets with strong magnetic fields such as Earth manage to deflect most of these charged particles as they approach.

A solar eclipse occurs when the Moon is between the Sun and the Earth.
