How many km is the Moon in size?

How many km is the Moon in size?

Size: With a diameter of 2,159 miles (3,475 kilometers), the Moon is just 1/4 the size of Earth. Distance from Earth: The Moon’s average distance from Earth is 238,000 miles (383,500 km). Orbit around Earth: It takes the Moon 27.3 Earth days to revolve around our planet one time.

What is the diameter of your planet moon in miles and kilometers?

But how big is the moon? The moon’s mean radius is 1,079.6 miles (1,737.5 kilometers) and the mean diameter is 2,159.2 miles (3,475 km). Compared to Earth, the moon is less than a third the width of our home planet, according to NASA (opens in new tab).

What is the diameter distance ratio for the Moon?

On average the moon is 380,000 km (235,000 miles) from the Earth, a distance of about 110 times its own diameter.

How do we know the diameter of the Moon?

What is the size of Moon?

How long is the orbit of the Moon in KM?

The Moon orbits Earth at a speed of 2,288 miles per hour (3,683 kilometers per hour). During this time it travels a distance of 1,423,000 miles (2,290,000 kilometers).

What are the diameters of the planets in KM?

• Mercury. 4,878 km. 0.5 mm. 0.38.
• Venus. 12,104 km. 1.2 mm. 0.95.
• Earth. 12,756 km. 1.3 mm. …
• Mars. 6,794 km. 0.7 mm. 0.53.
• Saturn. 120,660 km. 12.1 mm. …
• Uranus. 51,118 km. 5.1 mm. …
• Pluto. 2,300 km. .23 mm. 0.18.

What is the diameter of the Moon drawn to scale?

The diameter of the Moon is 3480 km or 27% of the Earth’s equatorial diameter of 12,756 km. The mass of the moon is 1.23% of the mass of the Earth, or about 1/80th.

Why is the diameter of the Moon?

The equatorial diameter of the Moon is 3,476.28 km. And the polar diameter of the Moon is 3,471.94 km. In other words, the Moon’s diameter from side to side is 4.34 km more than its distance from pole to pole.

How was measured the size and the distance of the Moon?

The Ancient Greeks used Lunar eclipses – the phenomena of the Earth passing directly between the sun and the Moon – to determine the distance from the Earth to its satellite. It’s a simple matter of tracking and timing how long it takes the Earth’s shadow to cross over the Moon.

Is the Moon 1 3 the size of Earth?

2) How big is the Moon? 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.

How far is the Moon from Earth in KM?

The average distance between the Earth and the Moon is 384 400 km (238 855 miles).

How to calculate diameter?

It is twice the length of the radius of a circle, i.e., Diameter = 2 × Radius.

How do you check the diameter?

Just divide the circumference by π to find the diameter. For example, if your circle has a circumference of 23 inches, the diameter would be 23/π, or approximately 7.32 inches. If you only know the area of the circle, use the formula diameter = 2 x √(area/π).

Is every moon the same size?

In fact, the moon and sun are rarely exactly the same size. The moon’s distance from Earth varies slightly over the course of a single month. So the moon’s apparent size in our sky is always changing. For part of every month, the moon is in a far part of its orbit from Earth.

Has a moon half its size?

Answer and Explanation: None of the eight planets in our solar system have a moon more than half its size. Pluto, a dwarf planet, has a moon that is slightly more than half…

Is the moon different sizes?

The moon always occupies roughly 0.52 angular degrees on the sky, or about the size of a thumb tip held at arm’s length. That changes by a minuscule amount between lunar cycles, with the moon’s apparent size getting up to 14 percent larger than normal during its closest approach to Earth.

What is the diameter of the Earth in km and miles?

Earth’s circumference (the distance all the way around the equator) is 24,901 miles (40,075 kilometers). Its diameter (the distance from one side to the other through Earth’s center) is 7,926 miles (about 12,756 kilometers).

Which planet has a diameter of 12742 km?

Earth has a diameter of 12,742 km and a surface area of 5.1 x 108 km2. Its volume of 1.08 x 1012 km3 gives the planet the largest volume of any of the terrestrial planets. Mars is also a small planet, the second smallest in our Solar System.

Is the Moon about 1/2 the size of Earth’s diameter?

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.

What planet has a diameter of 12000 km?

Venus, the second planet away from the Sun, is Earth’s closest neighbor. It is about the same size as the Earth, a little over 12,000 kilometers (7300 miles) in diameter.
