The Earth has a diameter of 12742km on average. It is a slightly squashed sphere though, due to its spin pushing out at the equator. Its polar diameter is 12714km, while its diameter at the equator is 12756km.

The diameter of the moon is 3474km.

Which eclipses occur when the tilt of the moon's orbit around the earth is tilted at zero to the earth's orbit?

This is when a Solar Eclipse occurs, the total eclipse happens when the moon's apparent size is bigger than the sun's and the moon blocks out nearly all of the sun's light - thus making stars appear.


Why does an objects gets attracted towards moon when it leaves the earth's gravitational field?

The moon orbits Earth because it is held there by Earth's gravity. The moon is going fast enough that it won't hit Earth, but at the same time is being pulled back in at the same rate it flies away. The same is true for why Earth itself doesn't fly into the sun. the sun is MUCH MUCH MUCH further away than the earth is, so it is attracted to earth because the difference in size and gravity favour the earth. If it was to be attracted to the sun, the sun would need to be bigger or closer (both of which it is doing at aconstant rate, but very gradually over a long perios of time)


Relationship between the size and weight of an object and the amount of friction that is present?

The physical size is unimportant - you can have a huge object that weighs less than a small one. The heavier the object is - the greater the friction.


A planet closet in size to earth?

Venus is a planet that is closest in size to Earth. It has similar bulk composition and gravity to Earth too.


How many kinds of eclipse are there?

On Earth, we get solar eclipses and lunar eclipses. A solar eclipse is when the Sun is obscured by all or part of the moon so that there is a shadow cast directly onto the surface of the earth. A lunar eclipse is when the Moon passes wholly or partially through the shadow of the Earth caused by the Sun, which darkens the Moon, or changes it distinctly reddish. Obviously in other positions in space, other kinds of eclipses would be possible. For instance, Mars has two moons, so it two different kinds of lunar eclipses. On a planet orbiting a binary star, you might speak of an eclipse when one star passes behind another, etc. There are some other complicated kinds of eclipse like the "Analemma Eclipse" in this picture " http://bethlapides.com/images//tutulemma.jpg "

What causes the moon to change it size and what effect does this have on earth?

The moon circles the Earth on a schedule that is approximately 28 days. As it does so the relationship between the Earth and the Sun changes and sunlight shines on different parts of the moon's surface, giving it a different appearance from Earth. Just as the Moon is attracted to Earth by gravity, the Earth too is attracted to the Moon. The oceans are affected by the Moon and the water rises toward the Moon, giving us tidal variations.

Is mercury or the moon closer to earth's size?

Mercury is larger than the moon and so is closer in size to Earth than the moon is. It should be noted that Mercury is closer in size to the moon than it is to Earth.


How are the size and mass of the moon different for that of the earth?

Size: The Moon has about 1/4 of the diameter of Earth. Mass: The Moon has about 1/81 of the mass of Earth.


Why do the earth and moon appear the same size?

The Earth and Moon appear the same size in the sky when viewed from Earth because the Moon is about 1/4 the size of Earth and is about 1/4 as far away from Earth as the Earth is from the Moon. This alignment creates the illusion that they have the same apparent size.


How does the size of the moon compare to the size of the moon?

The size of the Earth is significantly larger than the size of the Moon. Earth has a diameter of about 12,742 kilometers, while the Moon's diameter is about 3,474 kilometers, making Earth roughly 3.7 times larger than the Moon.
