Is+Pluto+a+Planet?

Introduction Since 2004, two rovers have been on Mars: Spirit and Opportunity. The rovers have found evidence of water on Mars. Because of the success of the Mars rovers, NASA is planning to send a rover to each planet in the solar system to research if there is water on any of the other planets. It is going to cost millions to send the rovers via a rocket.

There are three characteristics that all true planets share. A planet: 1) is in orbit around the sun, 2) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, 3) has cleared the neighborhood around its orbit.

A dwarf planet shares the first two characteristics, but 1) has not cleared the neighborhood around its orbit and 2) is not a satellite.
