What is the 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 of moon Class 9?

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

Is the Moon 60 miles away?

The average distance between the Earth and the Moon is 384 400 km (238 855 miles). The Moon's elliptical orbit with the distances at apogee and perigee. Note that the Earth is not at the very centre of the orbit and that the eccentricity of the orbit has been exaggerated here! Credit: NASA/Luc Viator/Affelia Wibisono.

What is the Moons radius of orbit?

The Moon's orbit (its circular path around the Earth) is indeed getting larger, at a rate of about 3.8 centimeters per year. (The Moon's orbit has a radius of 384,000 km.)

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.

What is radius of circle class 9?

The radius of a circle is the length of the line from the centre to any point on its edge. It can also be defined as, the distance from the centre of the circle to any point on the circle is called the radius.

What is radius of circle Class 4?

Radius – Radius is any line segment from center to the edge of the circle. All radii of the circle are equidistant from the edge of the circle i.e all radius are equal in length.

What is radius of circle class 10?

Radius is equal to half of the diameter of the circle. If the diameter is 10 cm, then radius will be equal to 5 cm.

How long is 1 hour in space?

Explanation: The clocks in space tick more slowly than clocks on Earth., HENCE COVERING LESS TIME AS COMPARED TO EARTH IN THE SAME DURATION. One hour on Earth is 0.0026 seconds in space. Thus, upon calculation we find that one hour on Earth is equivalent to seven years in space.

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 long was a day 2000 years ago?

In Earth's early history, a day was 23.5 hours and a year lasted 372 days.

How close can a moon orbit?

I say average because the Moon actually follows an elliptical orbit. At its closest point, it's only 362,600 km, and at its furthest point, it's 405,400 kilometers.

How fast is moon moving?

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 is radius of an orbit?

The Bohr radius, symbolized a , is the mean radius of the orbit of an electron around the nucleus of a hydrogen atom at its ground state (lowest-energy level). The value of this radius is a physical constant; a is approximately equal to 5.29177 x 10 -11 meter (m).

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.

Does the Earth's moon have a name?

Moon Earth / Moon

Is the moon an egg?

The moon is not round From our planet's vantage point, the moon appears to be a perfectly round sphere — but it's actually egg-shaped. The moon's oval shape is a consequence of the ongoing gravitational tug-of-war between it and Earth, according to NASA.

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).
