It's a Meteoroid, It's a Meteorite, No, it's actually a Bolide! -- What is the difference between those rocks in space and what you are seeing tonight?
What is the difference between meteorites and meteoroids
Meteoroids are the small particles that fall to Earth's surface. They are usually only millimetres in size and they can't be seen without a telescope. Meteorites are the larger bits of rock that fall to Earth's surface. They're usually over one meter in size and they can be seen with the naked eye.
Meteoroids are smaller pieces of debris that orbit around the sun, while meteorites are larger pieces of debris that have fallen to Earth from space.
What is the atmosphere and how does that protect us on Earth?
The atmosphere around Earth is the air that surrounds the planet and contains water vapor, nitrogen, oxygen, and other gases. It is divided into five layers: the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
Oxygen is a gas that makes up about 20% of Earth's atmosphere. Nitrogen makes up 78%. Oxygen helps to protect us by providing a layer of ozone or O3 in the stratosphere. This layer absorbs UV radiation from the sun to protect life on Earth.
What causes meteors?
Meteors are pieces of space debris that enter the Earth's atmosphere. They can be caused by a meteoroid, asteroid, or comet.
Meteors are often called shooting stars when they pass through the Earth's atmosphere and produce a streak of light in the sky. They are also called falling stars when they are not visible to the naked eye but can be seen from a telescope.
What causes bolides?
Bolides are created when a meteoroid enters the Earth's atmosphere and starts to burn up.
A bolide is a fireball that can be seen as a meteor or meteorite. It is typically extremely bright, and it can last for many seconds before it fades away. They are often mistaken for meteors, but they are not actually meteors because they do not reach the Earth's surface.
Bolides are created when a meteoroid enters the Earth's atmosphere and starts to burn up. This event creates an extremely bright light which is known as a bolide.

The Nature of Meteoroids and What it Means for Earth's Atmosphere
Meteoroids are the small bits of rock and dust that come from outer space and enter Earth's atmosphere. They get their name because they appear to be shooting stars in the night sky.
Meteoroids are made up of different materials, but most are made up of silicate minerals or stony iron. The meteoroid becomes a meteor when it enters Earth's atmosphere. The heat from friction caused by Earth's atmosphere causes the meteoroid to light up, which is what we see as a shooting star or "shooting star".
Meteoroids can be many sizes, but on average they are about 1 millimeter in diameter. This means that an average-sized human would need to walk for about 10 miles before they could step on one with their bare feet!
What is a Bolide and How to Survive One?
An asteroid is a small rocky body that orbits the sun. Asteroids are also known as minor planets or planetoids. The first asteroid was discovered in 1801 by Italian astronomer Giuseppe Piazzi.
A bolide is a very bright meteor, especially one that explodes in the atmosphere. The term was coined by French astronomer Camille Flammarion in 1880, derived from the Greek βολίς (bolis), meaning "a missile."
The term "bolide" can be used to describe a very bright meteor, especially one that explodes in the atmosphere, or it can refer to an exceptionally brilliant celestial object such as Venus or Jupiter when seen near the horizon with atmospheric refraction.
The Importance of Watching the Skies: The List of Earth's Most Dangerous Events
There are many natural disasters that can happen on Earth. Some of them might be caused by humans, while some might not. It is important to know the signs and risks of these events so we can stop them from happening or prepare for them in advance.
A meteorologist is someone who studies weather and atmospheric conditions as they change over time. They use this knowledge to predict what will happen in the future and warn people about dangerous events that are going to take place.
