Q1: What are comets mostly made of?
Answer: Ice, dust and rock
They are often called dirty snowballs.
Q2: Which way do comet tails point?
Answer: Away from the Sun
Solar wind and light pressure push them.
Q3: How often does Halley's Comet return?
Answer: About every 76 years
It will next appear in 2061.
Q4: Who correctly predicted the return of Halley's Comet?
Answer: Edmond Halley
It returned in 1758 after his death.
Q5: Where do long-period comets come from?
Answer: The Oort Cloud
It lies far beyond Pluto.
Q6: Which comet crashed into Jupiter in 1994?
Answer: Shoemaker-Levy 9
Its fragments left dark scars.
Q7: Which spacecraft orbited comet 67P and sent down a lander?
Answer: Rosetta
The lander Philae touched down in 2014.
Q8: Which very bright comet was visible for about 18 months in 1996-97?
Answer: Hale-Bopp
It was one of the most widely seen comets.
Q9: Which medieval tapestry shows Halley's Comet in 1066?
Answer: Bayeux Tapestry
It appeared before the Battle of Hastings.

Comets Knowledge Quiz – Icy Wanderers

Comets are icy bodies left over from the birth of the solar system. When they approach the Sun, their ice turns to gas, forming a glowing head called a coma and long tails of gas and dust that always point away from the Sun.

Short-period comets, like Halley's, come from the Kuiper Belt and return within 200 years. Long-period comets come from the distant Oort Cloud and may take thousands of years to orbit. Comets have been seen as omens throughout history, appearing in art and chronicles.

Spacecraft have studied comets up close. Giotto flew past Halley, Deep Impact struck Tempel 1 and Rosetta orbited comet 67P, landing Philae on its surface. Comets may have brought water and organic molecules to the early Earth.
