Planetary motion
The warping of space which causes objects to orbit the sun.
What is Gravity
This planet has no permanent atmosphere and has the largest temperature range in the solar system.
What is Mercury?
This collapsed to form our solar system.
What is a Nebula (or cloud of nebula)?
This color star is the hottest.
This is another name for a shooting star.
What is a meteor?
What is the rotation?
The shape of a planet's orbit around the sun.
Ellipse
This is what caused the beginning of our solar system formation.
What is a supernova explosion somewhere in the galaxy?
This color star is the coldest.
These are made of ice and rock; known as 'dirty snowballs'.
What is a comet
What is the revolution around the sun?
This group of planets have higher density and no rings.
What are inner planets?
These objects combined to form the planets.
This is a difference between our sun and a white dwarf.
What is: our sun is younger OR our sun is cooler OR our sun is larger OR our sun is less dense OR our sun is burning H & He, white dwarf is burning He & C.
This is found between Mars and Jupiter
What is an asteroid?
These two forces balance objects that orbit another object
What are gravity and inertia?
This is the hottest planet due to Carbon dioxide in its atmosphere.
What is Venus?
These were formed from the left over material at the end of our solar system formation.
What are planets? (and also comets, moons, asteroids would be acceptable).
This is the 'rule' that stars on the Main Sequence follow.
What is hotter=brighter?
This is what we call a small 'space rock' that lands on Earth.
What is a meteorite?
This is the reason that the Northern hemisphere of Earth is warm in the summer.
What is because it is tilted towards the sun?
This planet has the largest volcano in the solar system, Olympus Mons.
What is Mars?
What happened to cause our sun to become a star?
What is fusion (or Hydrogen fusing to Helium)?
This is the reason that red giants are not on the main sequence.
They are cool but bright due to their size (do not follow rule hotter= brighter).
In one layer of the sun, hot gases rise through cooler gases as they travel to the top of the layer. The hot gases then cool and sink back down to become heated again. This process takes place in this layer of the sun.
