Spaceling — Outer Planets & Planet Systems Ringway Crossing

Hi!

I'm Spaceling.

Welcome to Ringway Crossing!

Will you help me investigate outer planets & planet systems?

The Grumblies have mixed up our clues.

Let's check the evidence!

Jupiter and Saturn are gas giants;

Uranus and Neptune are ice giants.

They are much larger than Earth

and lie beyond the rocky inner planets.

Which are gas giants?

  • A. Mercury and Earth
  • B. Jupiter and Saturn
  • C. Earth and Mars

The answer is B: Jupiter and Saturn

Jupiter and Saturn are gas giants;

Uranus and Neptune are ice giants.

They are much larger than Earth

and lie beyond the rocky inner planets.

That clue helps us make sense of this place.

All four giant planets have rings and moons,

although some rings are faint.

Rings are many pieces of material, not one solid platform.

Are rings one solid walkway?

  • A. No, they contain many particles
  • B. Yes
  • C. Only when seen from Earth

The answer is A: No, they contain many particles

All four giant planets have rings and moons,

although some rings are faint.

Hmm...

how does that connect to our first clue?

Our table lists small rocky inner worlds and larger outer giants.

It shows a useful pattern, while individual planet details still vary.

Which outer planets are ice giants?

  • B. Jupiter and Earth
  • C. Uranus and Neptune

The answer is C: Uranus and Neptune

Jupiter and Saturn are gas giants;
