Meteoroids

A Meteoroid is a small rocky or metallic object that travels throughout space. There can be 3 different types and the types are what they are made of.

Overview
Have you ever heard about Meteoroids, Meteors, and Meteorites? Can you differentiate them? Meteoroids, Meteors and Meteorites will inform you about space objects. A meteoroid is a small piece of rock which travels in outer space. When a meteoroid enters the atmosphere of Earth’s and burns up, it becomes a meteor which is also called as ‘Shooting Stars’. Whereas meteor that travels and survives on Earth is called meteoroid. There are many still information about Meteoroid, Meteor, and Meteorite. While most things are named for what they are, rocks in space are named partly for where they are. A small rocky or metallic object burning up in Earth's atmosphere is called a meteor. And a small rocky or metallic object that has already hit the Earth's surface is called a meteorite.

There are three types of meteoroid, based on what they're made out of. Most meteoroids contain nickel and iron. But how much of them is made of these metals varies. When a meteoroid burns up in the atmosphere as a meteor, its color is affected by what materials make it up and how fast it's moving. They can burn with an orange, yellow, blue, green, or even violet tint. Whenever a meteoroid hits a planet or moon, it creates a crater. These craters get eroded away on the Earth and other active bodies, because of volcanic activity and weather. But on less geologically active bodies like the Moon, they stay around a lot longer. This is why there are so many craters on the Moon. There are many famous meteorites which have fallen on the Earth’s surface. Here are some example of the most famous meteorites, including the Allende, the Willamette, the Hoba, and the Fukang Meteorite. On February 8, 1969 the Allende fell on Earth. Then, there were many scientists studied about this meteorite. They conclude that the Allende is made of various minerals, oxides, water, silicates, organic compounds, and sulfides. Whereas the Willamette is the largest meteorite which was found in the United States. The weighs is around 15.5 ton. Besides, the meteorite which was found in Namibia, Africa was the Hoba. It is around 60 tone rock and very large. A fireball is a bright meteor which can be seen in the day time. That’s why it cannot be seen at night due to it occurs during daylight hours. Actually, there are 20 main showers. However, Perseids and Geminids are two big meteor shower which occur each year on August for Preseids and December for Geminids. Meteor shower occurs when a large number of meteors appear in a close time frame in a particular part of sky. It happens due to comet leaves debris when orbiting the solar system. The size of meteor is smaller than a baseball and same with pebble.
