This planet is the largest in the solar system, being approximately 2.5 times as massive as all of the other planets in the Solar System combined.
What is Jupiter?
All the planets in the solar system spin and orbit this way because they formed from the same cloud of spinning gas & dust.
What is Counter Clockwise?
This small icy world is not considered a planet because it has not cleared the path of its orbit and at some points passes through Neptune's orbit
What is Pluto?
This planet appears to revolve the opposite direction of all the other planets, but it actually has a 177 degree tilt on its axis
What is Venus?
The hottest planet in the solar system
What is Venus?
This planet has the most moons in the whole solar system, with 274 and counting.
What is Saturn?
This is the approximate age of our solar system.
What is 4.6 billion years?
(Ranges of 4.5 - 5 billion years are acceptable)
This object is a collection of ice and dust and has an extremely eccentric orbit.
What is a comet?
The name of the first artificial satellite to orbit the earth.
What is Sputnik?
The only terrestrial planet that has two moons
What is Mars?

What is Titan?
The smallest planet in the solar system, smaller than even some moons
What is Mercury?
This planet appears to revolve on its side with a 97 degree tilt to its axis.
What is Uranus?
This theory proposes that the solar system originated from a rotating, disc shaped cloud of gas and dust, with the inner portion becoming the sun, and the outer portion becoming the planets.
What is the Solar Nebula Theory?
This collection of "space rocks" towards the inner part of the solar system contains leftover material from the formation of the solar system, including large amounts of metals.
What is the Asteroid Belt?
This is the year that man first stepped on the moon.
What is 1969?
Mars is thought to get its red color from this compound found on its surface.
What is iron / iron oxide / rust?
This prominent feature on Jupiter is thought to be a giant high pressure storm that has existed for at least 360 years.
What is the Great Red Spot?
This is an early theory on how the universe formed. It suggests the Sun could have torn apart a passing star and used that material to form the planets.
What is the Capture Theory / Catastrophic Theory?
This massive spherical cloud of icy body's surrounds the edge of our solar system for ~1.5 light years and contains many comets.
What is the Oort Cloud?
This Galilean moon has a thin icy crust on its surface, and is thought to have a liquid-water ocean under its surface that could possibly harbor life.
What is Europa?
