Quiz Answer Key and Fun Facts

1. What is the name of the moon which revolves round Neptune in a clockwise direction?

Answer: Triton

There are other small moons which revolve clockwise around other planets. Ananke, Carne, Pasiphae and Sinope revolve clockwise round Jupiter. Phoebe revolves round Saturn the same way. All other moons revolve in an anti-clockwise direction.

2. What is the Hourglass Nebula?

Answer: A planetary nebula

Telescopes weren't powerful enough in those days, so the Hourglass Nebula looked like a planet. It's called a planetary nebula.

3. Which planet rotates slower than it revolves round the Sun?

Answer: Venus

Can you imagine the whole month being dark? Well, that's just what would happen if you were on Venus. Venus also rotates in a clockwise direction, which is quite odd too.

4. What is M16 also known as?

Answer: Eagle Nebula

M16 is a Messier object, discovered by Charles Messier. The Eskimo Nebula can also be called NGC 2392. The Keyhole Nebula is part of a region in Carina, which is NGC 3372. The Helix Nebula is one of the closest planetary nebulae to earth.

5. What planet is Solis Lacus found on?

Answer: Mars

Solis Lacus is a dark spot found on Mars, also called "The Eye of Mars". It is right below Valles Marineris, a long system of canyons.

6. Which is NOT a type of galaxy?

Answer: Conical Galaxy

There is no such thing as a conical galaxy. Our Milky Way Galaxy is a spiral galaxy, shaped like a spiral staircase. An irregular galaxy is just scattered all over. Elliptical galaxies are oval-shaped or round.

7. Name the four Galilean moons in order, starting with the closest to Jupiter.

Answer: Io, Europa, Ganymede, Callisto

There are some other named moons of Jupiter which are either before Io or after Callisto, but not in between. The smallest named moon of Jupiter is Leda.

8. What are the names of stars that revolve around each other?

Answer: Binary stars

One such binary star is Sirius, which consists of Sirius A & B. Sirius A's magnitude is -1.46 and Sirius B's magnitude is 8.3. There is also actually some evidence that Sirius might be a triple star system.

9. Besides having an atmosphere, what is vital for a planet to have seasons?

Answer: The tilt of the axis

The tilt of the axis governs the angle at which the Sun's rays hit the planet. Sun is at the focus of the orbit. For example, if Planet X's South Pole is facing the Sun, it's nearest to the Sun as it can ever be. It's summer down there. Now, It moves away from the Sun and it is the farthest from the Sun as it can ever be.

The South Pole is facing away from the Sun. It's winter down there. The more the axis is tilted, the more the effect the Sun has on the planet.

10. There are three pillars of hydrogen gas in the Eagle Nebula. If you were travelling at the speed of light, how long would you take to travel from the bottom of the tallest pillar to the top?

Answer: 1 year

I used a calculator to figure out the distance from the Sun to Pluto. I had 0.00062 light years. Then I compared it with the gas pillar. I calculated that the distance from the top to bottom of the gas pillar is 1612.903225 times the distance from the Sun to Pluto! The Eagle Nebula is in the constellation Serpens.

A famous image of it was taken by the Hubble Space Telescope on April 1st, 1995. I hope you enjoyed my quiz!
