What is the radius of moon class 9th?

The mass and radius of moon are 7. 4×1022kg and 17. 4×106kg . Find the acceleration due to gravity at the moon .

What is the mass and radius of moon?

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

How many km is the Moon 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).

Does Earth have 2 moons?

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.

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.

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.

Why is the moon round?

Gravity is at work here. A body as massive as a planet or large moon has sufficient gravity to pull its solid rock, liquid oceans, and gaseous atmosphere into the shape of a sphere.

How heavy is the Moon?

The mass of the Moon is approximately 8.1 x 10^19 tons (7.3 x 10^22 kg or . 01 x Earth mass). The mean diameter of the Moon is 2,159 miles (3,476 km or . 27 x Earth diameter).

Is Russia bigger than the Moon?

Is Russia Wider than the Moon? The surface area of the Moon is equivalent to the surface area of Russia, the United States, and Canada combined. In terms of wideness, Russia has an east-west extent of around 9,000 km / 5,600 mi, and a north-south width of 2,500 to 4,000 km / 1,500 to 2,500 mi.

How much does the Moon cost?

But if $450,000 sounds like a lot of money to you, you'd better sit down before I tell you how much it will cost NASA to send astronauts to the moon again. $4.1 billion per four-person flight. That's $1,025,000,000 per astronaut. Image source: Getty Images.

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.

What is Earth's moon called?

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.

Does the moon spin?

Does the Moon spin on its axis? Yes! The time it takes for the Moon to rotate once on its axis is equal to the time it takes for the Moon to orbit once around Earth. This keeps the same side of the Moon facing towards Earth throughout the month.

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 move?

It travels around our planet once every 27.322 days in an elliptical orbit, an elongated circle. The Moon is tidally locked with Earth, which means that it spins on its axis exactly once each time it orbits our planet.

Is gold on the moon?

The moon isn't so barren after all. A 2009 NASA mission—in which a rocket slammed into the moon and a second spacecraft studied the blast—revealed that the lunar surface contains an array of compounds, including gold, silver, and mercury, according to PBS.

Does it rain on the moon?

The moon has a very thin atmosphere so it cannot trap heat or insulate the surface. There is no wind there, no clouds, no rain, no snow and no storms, but there is “day and night” and there are extreme differences in temperatures depending on where the sun is shining.
