100
These are made mostly of rocks, and iron in their inner core
What are Mercury, Venus, Earth, Mars
100
This is the first step of the Solar System formation
What is " a nearby supernova took place"
100
Otherwise called a "shooting star", this space object flares up once it enters a planet's atmosphere
What is a meteor?
100
This is when our Solar System was formed
What is 4.6 billion years ago
100
Process by which planets are formed from gas, dust and rocks
What is accretion
200
These planets are the most massive in size, but are very dense
What are Jupiter, Saturn, Uranus, Neptune.
200
This is the second step
What is "a solar nebula was formed (cloud of gas and dust)
200
Can be found far beyond Neptune, our last planet. This space object is made of frozen gases and ice.
What is a comet?
200
These are the 3 types of galaxies
What are elliptical, irregular, and spiral
200
These are the two forces acting on a star
What are gravity and nuclear fusion
300
This planet has the most moons, and is the largest planet in the solar system
What is Jupiter
300
this is the third step
What is shock waves caused the solar nebula (cloud of gas and dust) to contract and rotate.
300
This space object orbits between Jupiter and Mars
What is an Asteroid?
300
theory that suggests that the universe started with a huge expansion
What is the Big Bang Theory
300
These can be found in an area called the Oort Cloud
What are comets
400
This icy gas planet rotates on its axis
What is Uranus
400
This is the fourth step
What is "gravity pulled most of the gas and dust materials to the center, forming the Sun
400
This space object comes from asteroids; this is what it is called when it is flying in space.
What is meteoroid
400
a vast cluster of billions of stars held together by gravity
What is galaxy
400
This process powers the stars and allows them to burn for many years
What is Nuclear Fusion
500
Which planet/ planets has/ have rings?
All of the outer planets- Jupiter, Saturn, Uranus, Neptune
500
This is the last step
What is "planets are formed by way of accretion or "clumping together" of rocks, gas and dust.
500
This is what it is called when this space object lands on a planet surface
What is meteorite
500
As the solar nebula rotated, these formed on the inner and outer edges of the solar system
What are planets
500
Stars are made of these gases
What is Hydrogen and Helium
