Our moon is considered a dwarf planet

Lunar facts
  • When we look from the earth to the moon, we always see the same side. Until the first photos of Luna 3 were sent in 1959, nobody knew the back of the moon.
  • The moon is about twice the size of the dwarf planet Pluto.
  • The man in the Moon has not always been interpreted as a man. The people of India see an old woman with a spinning wheel in it. The people of Mexico see a rabbit!
  • Compared to the earth, the moon is not very small. Sometimes the earth and moon are also called Double system or binary system designated.

The moon is the only one Trabant the earth. A satellite is another name for a moon on a planet. Most of the time we say or write the moon, if the earth moon is meant, and a moonif it means a satellite from another planet.
Viewed from Earth, the moon is the brightest and largest object in the solar system, just after the sun.

The moon is our closest neighbor in space.

How big is the moon?

Most of the planets in the solar system are much larger than their moons. The moon has a diameter of almost 3500 km. This means that the moon is not very small compared to the earth. That is why the earth and moon occasionally become too Double system or binary system called.

Size comparison between the earth and the moon

What is the surface of the moon like? [Edit]

Astronaut Harrison Schmitt collects rocks on the moon during the Apollo 17 mission.

The moon has no atmosphere at all. There is also no liquid water on its surface. It gets very hot during the day, but freezing at night. A moon visitor therefore needs a space suit and a supply of breathing air.

The moon has many crater on its surface. The largest has a diameter of 2500 km and will South Pole Aitken Basin called. That makes it twice the size of the European Union! It is the largest known crater in the solar system.

We believe that almost all of the craters on moons and planets were caused by large rocks that hit them long ago. You also will be Impact crater called.

Some of the lunar craters look like rays emanating from them. These rays are ejected stones that were scattered over the moon upon impact. Some craters near the pole may contain water.

There are darker areas that Maria to be named. These are large lava lakes that solidified a long time ago. Most of the Maria are on the earth-facing side of the moon. The lighter areas are the plateaus of the moon.

How long is a day on the moon? [Edit]

The moon takes a little over 27 days to be a full one rotation to perform itself.

How long is a year on the moon?

The moon also takes 27 days to orbit the earth once. That is why we always see the same side of the moon when we look from the earth. We call this side the earth-facing Page. We call the other side that remote from the earth Page. In 1959 a probe sent us images of the back of the moon. That was the first time anyone could see what she looked like.

What is the moon made of?

The surface of the moon is full of stones and dust. It is approximately 70 km thick on the face of the earth and 100 km on the far side. It is thinner under the Maria and thicker under the plateaus. Perhaps there is more Maria on the earth-facing side because the lava there managed to flow into craters more easily.

It is believed that the moon is a small one core (Center) has a diameter of 300 km.

How heavy would lunar gravity make me? [Edit]

If you were on the moon, you would have less than a quarter of your earth's weight there. (Because of this, it was quite easy for the astronauts on the moon to collect stones there.)

Who was it named after? [Edit]

Diana, the goddess of the moon in Roman mythology

The names "moon" and "month" both come from the ancient Greek name for the moon, "Mene". There were other names for the moon such as "Selene" and "Luna". Selene was the Greek goddess of the moon. Luna was the Roman goddess of the moon. The Romans also connected their goddess Diana to the moon.

Why does the moon always show us the same side?

Scientists believe that a very long time ago the moon spun faster than it does today. If there had already been someone at that time who observed the moon from the earth, he would be able to see a rotating moon, with each side and each crater gradually pointing to the earth.

Through the Tidal effectcaused by the gravitation of both celestial bodies, the moon has adjusted its rotation to the orbit time.
