Planets
Mercury
What is the closest planet to the Sun?
Fun fact: Despite being 430°C at it's surface and the closest planet to the sun, it is NOT the hottest planet in our Solar System.
The Milky Way.
What is our home Galaxy called?
Fun fact: It contains over 200 billion stars, is a barred spiral galaxy with a supermassive black hole at its center, and is on a collision course with the Andromeda Galaxy.
Sputnik
What was the first artificial satellite called?
Key point: Launched by the USSR in 1957.
Kilograms
Big Bang
What is the name of a scientific theory explaining the origin of the universe?
Fun Fact: The Universe started from a singularity ~13.8 billion years ago.
Neptune.
What is the furthest away Planet in our Solar System?
Fun Facts: Neptune has temperatures as low as -221°C and Supersonic winds that reach 1300mph. It's largest Moon, Triton, has geysers that spray ice into space.
A huge collection of stars, gas and dust held together by gravity.
What is the definition of a Galaxy?
Fun fact: Our sun is one of an estimated 100 to 400 billion stars that orbit a central supermassive black hole called Sagittarius A
Yuri Gagarin.
Who was the first human in Space?
Key point: Flew in 1961 aboard Vostok 1.
Did the USSR win the Space Race?
Newtons
What are the units of weight?
A theory that suggests the Universe has always existed.
What is the Steady State theory?
Key point: This theory suggests that the Universe has no beginning or end, it is an infinite loop.
Mars.
What planet is known as "the Red planet" / Which planet is the most habitable after Earth?
Fun Fact: Mars is home to Olympus Mons, the largest Volcano in our Solar System.
A body that orbits around a star.
What is the definition of a Planet?
Fun fact: The four planets closest to the Sun are rocky, like Earth, while the four outer planets are massive balls of gas and ice.
1969
What year was the Moon Landing?
Key point: It was called the Apollo 11 mission.
Mass x Gravity
What is the formula to calculate weight?
Earth's rotation on it's axis.
What is the cause of day and night?
Fun fact: You are spinning at over 1,000 miles per hour at the equator, but you don't feel it because the speed is constant and gravity keeps you on the ground.
Jupiter
Which planet is the largest in our Solar System?
Fun Facts: Every single other planet could fit inside Jupiter, and it also has over 90 moons.
This object controls our tides.
What does the moon do?
Fun fact: It is slowly drifting away from Earth at a rate of about 3.8 cm per year.
Space Shuttle Challenger
Why do we have seasons?
Fun facts: There is a theory in which Earth's current 23.5-degree axial tilt, was caused by a colossal impact with a Mars-sized protoplanet named Theia very early in Earth's history.
The moon keeps our tilt in check!
1980.
What year were Saturn's rings caught on film for the first time?
Fun Fact: Saturn's famous rings are not solid but are made up of billions of ice and rock particles, ranging from dust grains to chunks as big as mountains.
Pluto
Which planet was no longer classified as a planet as of 2006?
Fun Facts: Pluto is a dwarf planet in the Kuiper Belt with five moons, a heart-shaped region on its surface, and a thin atmosphere of nitrogen, methane, and carbon monoxide. It's orbit is so eccentric it sometimes goes inside Neptune's orbit.
Dennis Tito.
Who was the first Space Tourist?
Key point: Flew to the ISS in 2001.
A celestial object consisting of a nucleus of ice and dust and, when near the sun, a ‘tail’ of gas and dust particles pointing away from the sun.
What is a comet?
Fun fact: As they approach the Sun, a glowing "coma" and tail form as the ice turns to gas, and a meteor shower occurs when Earth passes through a comet's debris trail. While most are too small or far away to see, some, like the famous Halley's Comet, are visible from Earth.
A region of space with gravity so strong that nothing, not even light, can escape.
What is a black hole?
Fun fact: Black holes have mind-bending properties like warping time and stretching objects into a long shape, a process called "spaghettification". They come in various sizes, from tiny ones that could fit in a pocket to supermassive ones at the center of most galaxies, like our own Milky Way's Sagittarius A.
