What is the radius of moon in physics?
The mass of the moon is 7.34×1022kg and the radius is 1.74 ×106m.
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.
What is radius of sun and moon?
Radius of the Sun: 6.95 x 108 m. Radius of the Earth: 6.38 x 106 m. Orbital radius of the Earth around the Sun: 1.5 x 1011 m. Radius of the moon: 1.7 x 106 m.
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 is moon formula?
The Moon m = W g. W = 120 N. g = gravitational field strength g = 1.6 N/kg. m = 120 N ÷ 1.6 N/kg.
How big is the Moon ring?
It is the shape of the ice crystals that focuses the light into a halo around the Moon. Since the ice crystals are normally all hexagonal, the Moon’s ring is almost always the same size; it has a diameter of 22º.
Why is moon circular?
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.
Why is the Moon 400 times?
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.
What country is the same size as the Moon?
But that’s just one way of looking at things. Although the Moon is about as wide as Australia, it is actually much bigger when you think in terms of surface area. It turns out the surface of the Moon is much larger than that of Australia.
What are 5 interesting facts about the Moon?

What is bigger than sun?
Jupiter is the largest planet in the solar system. Jupiter’s mass is nearly 1000 times that of the Sun. Sirius, Pollux, Alpha Centauri A, UY Scuti etc. are some examples of stars bigger than the sun.
What star is bigger than the Sun?
Mu Cephi – about 1500 times the size of our sun. Betelgeuse – about 900 times the size of our sun. Antares – about 530 times the size of our sun. Deneb – about 145 times the size of our sun.
Is moon a star or not?
The star which is the formation of hot gasses, energy, light and heat, which doesn’t refer to the moon’s qualities. So the moon is not a planet or a star.
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.
Does any moon rotate?
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).
Is the Moon an egg shaped?
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.
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 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.
Is Pluto bigger than the Moon?
It is only half as wide as the United States. Pluto is smaller than Earth’s moon. This dwarf planet takes 248 Earth years to go around the sun.
