The Moon has impressed surprise and creativity for 1000’s of years. This picture appeared in a 1902 French movie referred to as “Le Voyage dans la Lune” (“A Journey to the Moon“).


It’s no surprise that we’re fascinated. The Moon is Earth’s solely pure satellite tv for pc and one which we will simply see most nights.

What makes the Moon glow?

The Moon doesn’t shine with its personal gentle. It merely displays gentle coming from the Solar.

Why does it seem like the Moon is altering form?

From Earth, it’d seem like the Moon is altering form every night time – from a tiny sliver to a half moon to a full moon and again once more. What’s really taking place is that from our spot on Earth, we see totally different elements of the Moon lit up by the Solar because the Moon travels in its orbit.

This graphic exhibits all eight moon phases we see because the Moon makes a whole orbit of Earth about each 4 weeks.

Because the Moon travels around Earth, totally different elements of it are lit up by the Solar. These adjustments within the Moon’s look from our view on Earth are referred to as moon phases. This graphic exhibits all eight moon phases we see because the Moon makes a whole orbit of Earth about each 4 weeks.

Is there really a “darkish aspect” of the Moon?

No. The Moon rotates by itself axis on the identical price that it orbits round Earth. Which means we all the time see the identical aspect of the Moon from our place on Earth. The aspect we do not see will get simply as a lot gentle, so a extra correct identify for that a part of the Moon is the “far aspect.”

We solely ever see one aspect of the Moon as a result of because it orbits around Earth, it additionally rotates by itself axis on the identical velocity.

The “far aspect” of the Moon seems to be very totally different than the close to aspect (see the primary photograph on this article). Discover how few darkish areas the far aspect has.

How did the Moon kind?

Scientists consider that the Moon fashioned early within the photovoltaic system’s historical past after Earth and an object concerning the measurement of Mars smashed into one another. The effect despatched chunks of Earth and the impactor into house that have been pulled collectively by gravity, creating the Moon.

How will we research the Moon?

Even 1000’s of years in the past, people drew photos to trace the adjustments of the Moon. Later, folks used their observations of the Moon to create calendars.

In the present day, we research the Moon utilizing telescopes and spacecraft. For instance, NASA’s Lunar Reconnaissance Orbiter has been circling the Moon and sending again measurements since 2009.

The Moon is the one different planetary physique that people have visited. On July 20, 1969, NASA astronauts Neil Armstrong and Buzz Aldrin have been the primary folks to set foot on the dusty floor of the Moon. Ten different American astronauts adopted. They collected a whole lot of kilos of lunar soil and rock samples, carried out experiments and put in gear for follow-up measurements.

Astronaut Buzz Aldrin arrange a number of scientific experiments whereas on the floor of the Moon in the course of the historic Apollo 11 mission. You’ll be able to see the lunar module, “Eagle,” within the background.

What do we all know concerning the Moon?

In the present day, we all know that the Moon is roofed by craters in addition to mud and particles from comets, asteroids and meteoroid impacts. We all know that the Moon’s darkish areas, referred to as maria – which is Latin for seas – aren’t really seas. As a substitute, they’re craters that lava seeped into billions of years in the past. We all know that the Moon has virtually no environment and solely about one-sixth of Earth’s gravity. We even know that there’s fairly a little bit of frozen water tucked away in craters near the Moon’s poles.

There isn’t any wind or air on the Moon to assist “erase” craters, so the floor is roofed with the stays of outdated and new impacts.

There are nonetheless many questions left to reply concerning the Moon. And essentially the most thrilling days of lunar exercise should still lie forward as NASA sends people on the subsequent missions to the Moon and ultimately to Mars.
