What is a comet
A comet is a celestial body that orbits the Sun. They are on the edge of our solar system betond the orbit of Pluto
What’s an asteroid
A chunk of rock and metal orbiting around the sun
What’s a Meteor
A meteor is an asteroid or other object that burns or vaporizes when it enters the earths atmosphere
What’s a meteorite
A meteorite is when very rarely a small piece of the Astrid will survive its journey through the atmosphere and land on the earths surface
What’s a meteoroid
A meteoroid is a meteor that hasn’t entered the earths atmosphere. It is just like an asteroid but much smaller.
What’s a dwarf planet
Dwarf planets are similar to planets except they don’t clear their orbit like planets do. The IAU defines a dwarf planet is an object in space that orbits around the sun. Is nearly a round shape. Has not cleared the neighborhood around its orbit. And is not a satellite
What’s a terrestrial planet
They are the first four planets they are referred to as terrestrial planets because they are mostly made of metal and rock. These planets are Mercury Venus Earth and Mars
What’s a gas planet
They are the remaining four palnets, they are significantly larger than the first 4 planets and they are mostly made from gasses. They are referred to as “gas giants”. These planets are Jupiter Saturn Uranus and Neptune
What’s the universe
Everything we can touch feel sense measure and detect this means it is everything that is living for example planets ,galaxies, dust clouds, light, and even time.
What’s the Solar system
Our solar system is the collection of 8 planets and their moon in orbit around the sun
What are galaxies
A galaxy is a massive collection of gas, dust, and billions of stars and their solar system that are held together by gravity.
Identify and describe our sun
Our Sun is a yellow dwarf star made up of mostly hydrogen and helium with small traces of other gases. Our Sun is about 4.6 or 4.7 million years old and in its main sequence(about halfway through its lifecycle)
What is the lifecycle of the sun
When the sun burns through all the hydrogen it will cool down and expand into a red giant and then loose its shape and become a planetary nebula and the core will eventually become a white dwarf star
Identify Meteors
Meteors burn up in earths atmosphere and never touch ground. They appear as “shooting stars” in the sky.
Identify Meteroites
If a meteor does not fully burn up in the atmosphere and hits the ground it is called a meteorite
Identify meteoroids
Meteoroids are like small astroids. They break off from the astroids comets and other space rocks and are traveling on a trajectory or path through space if the meteoroid enters the earths atmosphere it is called a meteor
Identify our galaxy
Our galaxy is the Milky Way
Describe our galaxy
Our Milky Way galaxy could have upwards of 3.2 trillion planets and 400 billion suns. It’s also estimated that there are approximately 2 trillion galaxies that we can see from our planet
What is the phrase to help us remeber the order of the planets
My Very Educated Mother Just Served Us Nachos
What is the order of the planets Starting with the closet to the sun.
The order of the planets are Mercury Venus Earth Mars Jupiter Saturn Uranus and Neptune.
What are the 3 similar features of the inner planets
The inner planets are inside the asteroid belt and are known as terrestrial planets they are small in size and they are all made of rocks minerals and metal they do not have rings and they have very few or no moons
What are the 3 similar features of the outer planets
The outer planets are the outside of the astroid belt and are known as the gas giants they are all large in size and they are made up of gases and therefore have no solid ground they all have rings and they all have a large number of moons
What is the diffrence between a dwarf planet and a planet
Dwarf planets share many characteristics that planets do fo example they are all most perfectly round or spherical in shape they orbit the sun and they are not satellites. However dwarf planets cannot clear their orbit. This is why all dwarf planets are located inside the astroid belt or the Kuiper Belt they cannot clear the space rocks around them like full planets can
