1. What is the stellar classification of our sun?

Answer: Yellow dwarf

Stars are classified using their color, temperature, and size. Our sun is a yellow dwarf. It will become a red giant and then a white dwarf near the of its life.

2. What is the largest dwarf planet in our solar system?

Answer: Pluto

Pluto is located in the Kuiper Belt and was once considered a planet. It was discovered in 1930 and was reclassified as a dwarf planet in 2006.

3. Simply put, what is a bolide?

Answer: Meteor

A bolide is a rather brilliant meteor that often explodes when it goes through the Earth's atmosphere.

4. Which planet has moons named Io, Ganymede and Europa?

Answer: Jupiter

These are just three of Jupiter's moons. Io is covered with large explosive volcanoes. Europa is believed to have a liquid water ocean and Ganymede is larger than Mercury. Jupiter must be an unusual place.

5. If two pieces of the same type of metal touch in space they will permanently bond.

Answer: True

This claim is true. The process is also known as cold welding and occurs due to the lack of an atmosphere. It does not happen on the earth because there is always air or water between objects.

6. What noise is most common in space?

Answer: There is no natural sound in space

Because there is no atmosphere in space, there is no natural sound. Astronauts use radios to communicate while they are in space because radio waves can be sent and received.

7. Which one of these planets is the hottest?

Answer: Venus

Even though the Mercury is the planet nearest to the Sun, Venus is actually the hottest. That is because Venus has an extremely dense carbon-dioxide atmosphere, which causes a strong greenhouse effect.

8. A meteor shower is usually caused by which of the following?

Answer: A comet

A meteor shower is usually caused by a comet. They are a trail of debris that is left by a comet.

9. What was the first successful spaceflight by man?

The first successful human spaceflight was Vostok 1 with cosmonaut Yuri Gagarin in 1961.
