How big is the Moon NASA?

Size and Distance With a radius of about 1,080 miles (1,740 kilometers), the Moon is less than a third of the width of Earth. If Earth were the size of a nickel, the Moon would be about as big as a coffee bean. The Moon is an average of 238,855 miles (384,400 kilometers) away.

What did NASA find on the Moon 2020?

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

What does NASA say about the Moon?

Facts About The Moon The Moon is Earth's only natural satellite and the fifth largest moon in the solar system. The Moon's presence helps stabilize our planet's wobble and moderate our climate. The Moon's distance from Earth is about 240,000 miles (385,000km). The Moon has a very thin atmosphere called an exosphere.

Who measured the Moon?

The jump Aristarchus made from terrestrial measurements of scale to the celestial is truly remarkable. Without any measures of the sizes of or distances to any celestial objects, he was able to measure both for the Moon.

What if the Moon was the same size as Earth?

Originally Answered: If the moon was made the same size as Earth, what would happen? Well, things would become lighter during night, the atmosphere would change drastically, the two astronomical bodies would move each other out of orbit and drift each time closer and faster until they collided.

Would the Earth survive without the moon?

Without the moon, a day on earth would only last six to twelve hours. There could be more than a thousand days in one year! That's because the Earth's rotation slows down over time thanks to the gravitational force — or pull of the moon — and without it, days would go by in a blink.

Can a moon have a moon?

Yes, it is possible for a moon to itself have moons and/or rings, and there are a few places where scientists have suggested that this is (or was) the case. However, moons tend to rotate slowly, and this makes it difficult for a moon's moon to find a stable orbit.
