Why is Mars known as the “Red Planet?”

Mars has a chemical called iron oxide (rust) in its soil that causes the surface to take on a reddish appearance.

What is the Oort Cloud (Beyond Pluto) and Kuiper Belt (Between Neptune and Pluto)

200

This is the second largest and lightest planet in the solar system. It's so light that its density would allow it to float on water.

What is Saturn.

300

If you take the photograph from the northern hemisphere, the star closest to the centre of the circles is

The northern pole star, or Polaris.

What will happen to our sun in the next stage of its life?

Red Giant - The star's outer layers will expand and become 100X larger than our sun. At this point it will engulf Mercury, Venus, Earth, and Mars and probably tear apart the gas giants and evaporate Saturn's rings. Doesn't that sound like a lovely time in our Solar System.

300

A chunk of rock from outer space that burns up in the atmosphere.

What is a meteor.

300

What is the difference between meteor and a meteorite?

400

What do the terms waxing and waning mean in relation to the moon phases?

When the phases are said to be waxing, the visible portion of the moon seems to be getting larger. When they are waning, the visible part seems to be getting smaller. The moon waxes and wanes from right to left.

400

Why is Venus considered the hottest planet in the Solar System?

Venus has a tremendous Greenhouse Effect – Due to a large amount of carbon dioxide in the atmosphere (98%) -the CO2 traps the heat and causes the surface temperature to reach around 700 Fahrenheit.

500

if you take a photograph in the southern hemisphere looking south, the star closest to the centre is

The southern pole star, Sigma Octantis

500

Stars 10 times larger than our sun can take an alternative path in life. What could be the end result after the star explodes (supernova)?

It could become a nebula, black hole, or neutron star.

500

Distances within the Solar System can be measured in what unit?

What is the speed of light (light minutes, light years, etc)

500

Why do comets develop tails?

Tails develop as the comet approaches the sun and the frozen gases begin to melt. The tail always points away from the sun due to the solar winds.

500

What is Jupiter’s “Great Red Spot" and Neptune's "Great Dark Spot"?

Both are huge storms (Hurricane) that have been circulating around the planet for hundreds of years.
