Question

Pluto is much smaller.

Pluto is much larger.

Pluto is about the size of the outer planets.

Pluto is about the size of the inner planets.

Answer 1

Pluto is about the size of the inner planets.

The four inner planets--Mercury, Venus, Earth and Mars--are known as terrestrial planets for their smaller size, solid surface, and similarity to Earth. The next four planets, looking outward from the Sun, are gas giants. They are larger than the terrestrial planets, have a larger number of satellites, and no solid surface. Beyond the gas giants, Pluto breaks the pattern by once again showing characteristics more like a terrestrial planet--small, solid surface, and only one (known) satellite.
