Quiz Answer Key and Fun Facts

1. How many planets in our solar system have rings?

Answer: 4

Jupiter, Saturn, Uranus and Neptune.

2. How far is a light year?

Answer: 5.88 trillion miles or 9.46 trillion km.

A light year is the distance light can travel in 1 year.

3. What is a meteoroid?

Answer: A small solid body outside the atmosphere.

According to Dictionary.com, 'A meteoroid is smaller than an asteroid and at least as large as a speck of dust.'

4. According to popular theory, what is a 'singularity'?

Answer: The centre of a black hole.

5. What is the angle of re-entry used by space craft returning into the Earth's atmosphere?

Answer: around 40 degrees.

Less than 28 degrees and it could bounce back, more than 38 degrees and the drag could cause it to burn up.

6. What is an Astronomical Unit?

Answer: The average distance of the Earth from the Sun.

Usually used for distances inside our Solar System. An AU is equal to approximately 93 million miles or 150 million kilometers.

7. What is a black hole?

Answer: A collapsed star.

The gravitation of the star allows nothing to escape its pull, even light. Theoretically, the material that made up the star could fit inside a match box, but its mass would be the same, making it really difficult to slip into your pocket.

8. What is a nova?

Answer: A star that temporarily becomes brighter.

Novae are believed to be close binary stars, one component of which is usually a white dwarf and the other a red giant. Matter is transferred from the red giant to the white dwarf, on whose surface it accumulates, eventually leading to a thermonuclear explosion.

9. What is a supernova?

Answer: An exploding star expending its energy in a bright flash.

The extreme brightness will be temporary as it consumes itself.

10. Which is not a satellite of Neptune?

Answer: Umbriel.

Umbriel is a moon of Uranus.

11. What is a quasar?

Answer: QUAsi StellAr Radio source.

"An extremely distant celestial object, whose power output is thousands of times that of our entire galaxy."
Dictionary.com.

12. What is the closest star to Earth, after our Sun?

Answer: Proxima Centauri.

Along with Alpha Centauri A & B it is part of a triple system. It is believed to be only slightly bigger than Jupiter. Getting distances is difficult as each reference source has a different answer. Proxima seems to be standard at 4.22 light years from Earth. Rigel is 700+ light years away. Betelgeuse is 400-500 light years. Antares is given as 400-600 light years away.

13. What is a galactic year?

Answer: Time the Sun takes to orbit the center of galaxy.

Traveling at 155 miles/sec (250 km/sec) it takes about 225 million years.

14. How long is a galactic year?

Answer: 225,000,000 years.

That's traveling at 558,000 mph (900,000 kph). I guess it would be easy to forget to buy it a present.

15. What is the largest moon in our solar system?

Answer: Ganymede

Ganymede is a moon of Jupiter. Titan belongs to Saturn. Triton belongs to Neptune and Phobos is one of the moons of Mars.
