What is an asterism (constellation)?
A group of stars in a recognizable pattern
A large object that orbits a planet
A ball of ice in space
Our nearest star
What is a moon?
(unfunny fact: Earth's Moon is the only one that's capitalized!)
a large group of stars
an asteroid that enters the atmosphere
where a star explodes but is still there after the explosion
a large object that orbits a planet
What is a comet?
(A comet has four components: a nucleus, a coma, a dust tail and an ion tail)
a gas cloud in space
a rock in space
a ball of ice in space
a large ball of gas that gives off light by nuclear fusion
What is the Sun?
(It takes eight minutes for light reach Earth from the Sun.)
A large object that orbits a star
Our nearest star
A rock in space
Where a star explodes and is completely destroyed
What is a supernova?
(Many of the elements we're made of come from supernovae.
Everything from the oxygen you're breathing to the calcium in your bones, the iron in your blood and the silicon in your computer was brewed up in the heart of a star. As a supernova explodes, it unleashes a hurricane of nuclear reactions.)

What is a star?
(The most massive stars are the shortest lived)
a ball of ice in space
our nearest star
a large group of stars

What's a galaxy?
(The Andromeda galaxy is 2.537 million light-years away from Earth in the constellation Andromeda. Its 'closeness' to our planet makes it the most distant object visible to the naked eye on Earth.)
a large group of stars
a group of stars in a recognizable pattern
a large object that orbits a star
a large object that orbits a planet
What's a nebula?
(Named after the Latin word for “cloud”, nebulae are not only massive clouds of dust, hydrogen and helium gas, and plasma; they are also often “stellar nurseries” – i.e. the place where stars are born. And for centuries, distant galaxies were often mistaken for these massive clouds.)
a ball of ice in space
a rock in space
a gas cloud in space
our nearest star
What's an asteroid?
(Asteroids are leftovers of the early Solar System.)
a ball of ice in space
a rock in space
a gas cloud in space

Select the correct statements that related to
the length of time that it takes Earth to orbit the Sun:
(choose them all - remember them all)
365.2425 days (why we have a leap year every 4 years)
1 (Earth) year = 365.2425 days
Julius Caesar created the Julian calendar (with leap years) and recommended January as the start of a new year
A complete orbit around the Sun is called a period.
