Planets
The closest planet to the sun
What is Mercury?
This planet is nicknamed the "Red Planet".
What is Mars?
These are the two primary gases that make up the Jovian planets like Jupiter and Saturn.
What is Hydrogen and Helium?
This is the name of the supermassive black hole located at the center of the Milky Way galaxy.
What is Sagittarius A?*
This is the first stage of a star's life cycle, a giant cloud of gas and dust.
What is a Nebula?
A planet with 7 rings.
What is Saturn?
This is the largest planet in our solar system.
What is Jupiter?
The Sun is composed mostly of this lightest element, making up roughly 75% of its mass.
What is Hydrogen?
Our solar system is located on this smaller spiral arm, roughly 26,000–27,000 light-years from the galactic center.
What is the Orion Arm?
Stars spend 90% of their lives in this stable phase, fusing hydrogen into helium.
What is the Main Sequence?
This is the only planet that rotates on its axis clockwise.
What is Venus?
This planet is known for being unique because it orbits or rotates on its side.
What is Uranus?
It takes roughly this many minutes for light from the Sun to reach the Earth.
What is 8 minutes?
Approximately this many years, also known as a galactic year, are required for the Sun to complete one full revolution around the galactic center. (Note: Recent estimates vary, often cited around 225–240 million).
What is 225 million (or 240 million) years?
When a medium-mass star like our Sun dies, it leaves behind this hot, dense core.
What is a White Dwarf?
This is the only planet in our solar system known to have abundant liquid water.
What is Earth?
This planet was the first to be discovered through mathematical predictions, rather than direct observation.
What is Neptune?
Extending millions of miles into space, this outermost layer of the Sun’s atmosphere is only visible during a total solar eclipse.
What is the corona?
While the visible disk is about 100,000–120,000 light-years across, the extended halo of this invisible matter makes the galaxy much larger.
What is Dark Matter?
These massive stars are the largest in terms of volume in the universe.
What are Supergiants?
An exoplanet orbiting a G2-type star (similar to our Sun) about 1,400 light-years away in the constellation Cygnus
Kepler-452b
This celestial body, once considered the 9th planet, was reclassified as a dwarf planet in 2006.
What is Pluto?
This type of barred spiral galaxy contains our solar system and houses between 100 and 400 billion stars.
What is the Milky Way?
The Milky Way is predicted to collide and merge with this neighboring galaxy in about 4–5 billion years.
What is the Andromeda Galaxy?
This type of star has a mass less than about 8 times that of the sun and will not end in a supernova.
What is a Low/Medium Mass Star?
