How far is the Moon from Earth scale?

Lunar distance
A lunar distance, 384,399 km (238,854 mi), is the Moon’s average distance to Earth. The actual distance varies over the course of its orbit. The image compares the Moon’s apparent size when it is nearest and farthest from Earth.

The average distance between the Earth and the Moon is 384 400 km (238 855 miles). For younger students, you can tell them the Moon’s diameter is approximately 0.25 or ¼ that of Earth (3,475 km (Moon diameter)/ 12,742 km (Earth diameter) = ~0.25). This one’s another easy approximation to remember: The Moon is about one-fourth (or a quarter) the size of Earth in width. Put another way, Earth is about four times wider than the Moon. That’s just about as wide as the United States or Europe. Since the Moon and the Earth are approximately the same distance from the Sun, they receive sunlight of the same strength. So the temperature of the Earth and the Moon should be the same. It is the Moon’s lack of atmosphere that creates such extreme temperatures.

How far is space from Earth?

According to their data, the edge of space begins at 118km (73 miles) above sea level. Where is space? Until now, a simple nod to the sky may have sufficed, but it seems that with each passing year the final frontier is becoming a little more accessible. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space. But nobody knows for sure.

How far away is the sin?

As noted earlier, Earth’s average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun. The Moon orbits Earth at a speed of 2,288 miles per hour (3,683 kilometers per hour). This one’s another easy approximation to remember: The Moon is about one-fourth (or a quarter) the size of Earth in width. Put another way, Earth is about four times wider than the Moon. Why doesn’t the sun pull the moon away from earth? Short answer: Because the Moon is much closer to the Earth than it is to the Sun. This means the gravitational acceleration of the Earth toward the Sun is almost the same as is the gravitational acceleration of the Moon toward the Sun. The temperature of the sun varies from around 27 million degrees Fahrenheit (15 million degrees Celsius) at the core to only about 10,000 degrees F (5,500 degrees C) at the surface, according to NASA (opens in new tab).

Are there 3 moons on Earth?

Although the moon is our only permanent natural satellite, astronomers have discovered many other near-Earth objects that could be considered honorary ‘mini’ moons. Earth’s Moon is the fifth largest of the 200+ moons orbiting planets in our solar system. Earth’s only natural satellite is simply called the Moon because people didn’t know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. Due to its immense size, mass, and gravitational pull, Jupiter has the most satellites of any planet in the Solar System. At present, the Jovian system includes 80 known moons, though it is estimated that it may have over 200 moons and moonlets (the majority of which are yet to be confirmed and classified). A tiny second moon may once have orbited Earth before catastrophically slamming into the other one, a titanic clash that could explain why the two sides of the surviving lunar satellite are so different from each other, a new study suggests. But that’s just one way of looking at things. Although the Moon is about as wide as Australia, it is actually much bigger when you think in terms of surface area. It turns out the surface of the Moon is much larger than that of Australia.
