Several thousands. Most of them are the size of a grain of rice or smaller. A few each day may be the size of a baseball or occasionally the size of a Basketball.
Once a week or so, the Earth is hit by a rock the size of a car, and once every few months, we get hit by something the size of a house. A couple of months ago, a meteor the size of a house exploded over central Indonesia; it scared a lot of folks, but apparently did no damage.
The VAST majority of these burn up completely in the atmosphere, surviving as nothing but dust. A few do make it to the Earth, often in small (fist-sized) chunks. Very few do any damage. Only a few people are known to have been hit by a meteorite; there was a boy in Germany last year who was struck in the hand by a meteorite the size of a pea.
Every few hundred years, bigger things hit the Earth, and some do a lot of damage. In 1908, a meteor or small comet exploded high in the atmosphere near a place called Tunguska, Siberia, causing an explosion the size of a nuclear bomb. 5000 years ago, a meteor struck in the Indian ocean causing a tsunami, which may be the source of the "Great Flood" legends in Gilgamesh and Noah's Ark. 14000 years ago, something hit northern Canada causing the "Younger Dryas" mini-ice age.

What is it called when the moons shadow hits earth or earths shadows hit the moon?
It is called a solar eclipse when the Moon's shadow hits Earth, and a lunar eclipse when Earth's shadow hits the Moon.
A beam of sunlight hits earth at this location at an almost perpendicular angle?
When a beam of sunlight hits the Earth at an almost perpendicular angle, the intensity of sunlight is highest because the light is concentrated on a smaller area, resulting in more energy absorbed. This produces warmer temperatures compared to when sunlight hits at an oblique angle, where the same amount of energy is spread over a larger area, resulting in cooler temperatures.
Is the earth luminous?
The Earth itself is not luminous. It reflects sunlight that hits its surface, which gives it the appearance of being illuminated. The Earth does not generate its own light like the sun or other luminous objects.
What is a meteroroid called when it hits earth?
A meteoroid is called a meteor when it enters Earth's atmosphere and creates a streak of light in the sky due to the heat generated by friction. If any part of the meteoroid survives the journey and hits the ground, it is then considered a meteorite.
Which term describes rain that freezes when it hits the earths surface?
The term for rain that freezes when it hits the earth's surface is freezing rain.
How long does the star takes to reach earth?
Stars don't travel to earth. But the light and other radiation that they emit spreads out in every direction from the star, and some of it eventually hits the earth. Starting out from the star, it takes the light 1 year to reach the earth for every 5,878,700,000,000 miles it has to cover to get here.
Is there a chance of a meteor hits the earth?
every chance, but size in the question, Scientists estimate that between 36 and 166 meteorites hit the earth, larger than 10 grammes in weight, every million square Kilometres per year
When will meteoride come to earth?
Every year, several small meteorites hit the Earth. Very occasionally (hundreds or thousands of years) a big one hits the Earth and causes destruction. It is not yet possible to predict such events.
What happens to the sunlight that hits the surface of the Earth?
Sunlight that hits the Earth's surface is absorbed by the Earth. It is then reflected back.
After it hits earth a meteoroid is called a?
After it hits Earth, a meteoroid is called a meteor.
When a meteor hits the earth what does it form?
When a meteor hits the Earth it forms a crater.
Will the earth be distroyed when the meteor hits earth?
Not likely.
Will you die if the sun hits the earth?
Yes if you are on the earth.
WILL AN ASTEROID HITS THE EARTH?
Technically, if it hits the Earth it's not an "asteroid", it's a "meteorite". And yes, meteorites hit the Earth all the time.
What is it called when the moons shadow hits earth or earths shadows hit the moon?
It is called a solar eclipse when the Moon's shadow hits Earth, and a lunar eclipse when Earth's shadow hits the Moon.
When the sun light hits the earth what does it do?
About 35% of the light that hits the Earth is reflected away immediately, back into space. The remainder of the light hits the Earth. Some of it is absorbed or scattered in the atmosphere, and much of it reaches the surface as light. Sunlight that is absorbed by the surface heats the Earth.
When light hits a material what are three things that can happen?
When light hits a material, it can be absorbed, reflected, or transmitted through the material. Absorption results in the light energy being converted to other forms of energy, such as heat. Reflection involves the light bouncing off the surface of the material. Transmission is when the light passes through the material.
