How large is the Moon in KM?

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). The moon’s equatorial circumference is 6,783.5 miles (10,917 km).

What is radius of moon Class 9?

The mass of the moon is 7.34×1022kg and the radius is 1.74 ×106m.

Is the Moon exactly round?

What is the Moon really shaped like? The Moon is shaped like an imperfect sphere. From a distance, it looks nearly round. Seen up close, the Moon’s surface is a three-dimensional landscape of mountains, valleys, and craters.

What is a moon made of?

The average composition of the lunar surface by weight is roughly 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, 0.42% chromium, 0.18% titanium and 0.12% manganese. Orbiting spacecraft have found traces of water on the lunar surface that may have originated from deep underground.

What Colour is the Moon?

What color is the Moon? It depends on the night. Outside of the Earth’s atmosphere, the dark Moon, which shines by reflected sunlight, appears a magnificently brown-tinged gray. Viewed from inside the Earth’s atmosphere, though, the moon can appear quite different.

What is full moon Class 8?

Full Moon: When the moon appears as a full disc, the entire side facing us is lit up and is called Full Moon.

What is moon Class 8?

The moon completes one rotation on its axis as it completes one revolution around the earth. The moon has dusty and barren surface with craters, steep and high mountains. The moon has no atmosphere and no water. On July 21, 1969 (Indian time), Neil Armstrong landed on the moon for the first time.

What is moon surface Class 8?

The moon’s surface is covered by rocks and loose dirt which we call lunar soil. It is pockmarked with craters of different sizes because of meteorites that hit its surface. On earth, these meteorites burn up in our atmosphere before they reach the ground.

Why does the Moon not spin?

An enduring myth about the Moon is that it doesn’t rotate. While it’s true that the Moon keeps the same face to us, this only happens because the Moon rotates at the same rate as its orbital motion, a special case of tidal locking called synchronous rotation.

How fast does the Moon spin?

With more reading I learned that it takes about the same amount of time for the moon to rotate on its axis (27.3 days) as it does for the moon to make one revolution around Earth (29.5 days).

What is the shape of moon called?

The moon is named for its shape, which can be a waxing crescent (growing) or waning crescent (diminishing). And we also have gibbous moons, indicating a shape that is unequally curved outward on both sides, but not full. Gibbous moons also wax and wane depending on its time in the cycle.

Is the Moon 235000 miles away?

On average the moon is 380,000 km (235,000 miles) from the Earth, a distance of about 110 times its own diameter. A tennis ball would then have to be 110 x 6.7 cm = 7.37 meters (about 24 feet) from the basketball. That’s a lot farther than most people would think!

Is the Moon exactly 400?

Even though the Moon is 400 times smaller than the Sun, it’s also about 400 times closer to Earth than the Sun is. This means that from Earth, the Moon and the Sun appear to be roughly the same size in the sky.

Is the Earth 4 times bigger than 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.

Is it possible to walk around the Moon?

A 2014 NASA study looked at the theoretical maximum walking speed on the Moon, finding that you could walk at 5km/h before you would need to break into a loping run. At this speed, you would travel the 10,900km circumference of the Moon in 91 days of non-stop walking.
