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

What is the radius and mass of moon?

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

What is the radius of the moon in scientific notation?

This is an Expert-Verified Answer The radius of the moon in its scientific notation is 1.74 x 106 meters. Explanation: Using scientific notation, one can express extremely big or extremely small values.

How big is the moon diameter?

3,474.8 km Moon / Diameter

Does Earth have 2 moons?

Moon Earth / Moon

Is the moon an exact circle?

The moon is a spheroid, not completely round but egg-shaped, according to NASA's Lunar Reconnaissance Orbiter website. The moon's shape derives from its rotation, with the large end of the egg-shape pointing toward the Earth.

Does the moon Have a Name?

Well, the moon does technically have a name: “the moon.” You're assuming its name is generic for the category. But the moniker is actually exquisitely specific; until Galileo discovered the moons of Jupiter four centuries ago, ours was one-of-a-kind.

What is radius of moon Class 9?

The mass of the moon is 7.35×1022kg. The radius of the moon is 1.74×106 m.

What is the radius of mass?

The Schwarzschild radius of a body is proportional to its mass and therefore to its volume, assuming that the body has a constant mass-density. In contrast, the physical radius of the body is proportional to the cube root of its volume.

What is the notation for radius?

The radius is represented by the lowercase letter r.

How do you find the radius?

How do you find the radius of a circle?

The radius of a circle from the area: if you know the area A , the radius is r = √(A / π) .
The radius of a circle from circumference: if you know the circumference c , the radius is r = c / (2 * π) .

How do you find the radius of a shape?

Find the radius if you know the diameter. The radius is half the diameter, so use the formula r = D/2.

What is moon made of?

It is made of oxygen, silicon, magnesium, iron, calcium, and aluminum, with small amounts of titanium, uranium, thorium, potassium, and hydrogen. Long ago the Moon had active volcanoes, but today they are all dormant and have not erupted for millions of years.

Why is the moon so big?

The Moon illusion is the name for this trick our brains play on us. Photographs prove that the Moon is the same width near the horizon as when it's high in the sky, but that's not what we perceive with our eyes. Thus it's an illusion rooted in the way our brains process visual information.

Is there water on the moon?

Recent unmanned missions to the moon have discovered a few remnants of water ice trapped in sheltered craters around the poles, but much of the moon's surface is now dry.

Will Earth lose the Moon?

Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth. Now, our Sun is expected to enter its Red Giant phase in about 6 to 7 billion years.

Did the Earth used to be purple?

The earliest life on Earth might have been just as purple as it is green today, a scientist claims. Ancient microbes might have used a molecule other than chlorophyll to harness the Sun's rays, one that gave the organisms a violet hue.

Why does the Moon not rotate?

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.

Does the Moon spin?

The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth. If the moon were to rotate quickly (several times each month) or not rotate at all, Earth would be exposed to all sides of the moon (i.e. multiple different views).

Does the Moon move in a circle?

The moon travels around the Earth in an elliptical orbit, a slightly stretched-out circle. When the moon is closest to Earth, its rotation is slower than its journey through space, allowing observers to see an additional 8 degrees on the eastern side.
