Asked by Wiki User

Of what? Mammals? Animals? In terms of absolute size, or relative to their mass? Pose a more accurate question please. However, fun fact: Neanderthal's brains were both heavier and larger, proportional to their body size, than modern humans brains. Bigger isn't always better.

What is the difference between dwarf planets and regular planets?

User Avatar

Asked by Wiki User

Dwarf planets are smaller than regular planets.

Dwarf planets are smaller than the 8 major planets of our solar system. They are not quite planets as they have not cleared their orbit of sufficient matter. They are roughly spherical in shape and orbit the sun directly, so fulfil these two criteria, but have not achieved the third (sufficiently clearing their orbits).

Asked by Wiki User

Here are some facts about Pluto:

  • In 2006, got reclassified from a "planet" to a "dwarf planet".
  • Pluto gets closer to the Sun than Neptune about 10% of its orbit.
  • The temperature is around -230°C (-382°F).
  • Pluto is smaller than the Earth's Moon.
  • New Horizons was the first spacecraft to visit Pluto and sent back very good images of the surface.
  • Pluto is 3,670 million miles away from the Sun.
  • It takes 248 Earth years for Pluto to orbit around the Sun.
  • One day on Pluto is about 6 and a half earth days.
  • Pluto has 5 moons: Charon, Hydra and Nix Kerberos and Styx.
  • Pluto and Charon spin on an axis of about 123 degrees.
  • Pluto has a large rock core, an icy mantle and an icy surface.
  • Pluto and Charon orbit together so both of them only see one side of each other.
  • Because of Pluto's weird orbit, it is sometimes closer to the earth than Neptune.
