Our Solar System

has not cleared other large objects from the region it crosses during its orbit. (Its gravity is not great enough to cause other orbiting objects to impact, or crash into, its surface or be ejected from our solar system.) is not a satellite of another object. Pluto meets all of these requirements. It is now the best example of a dwarf planet.

Potential discovery of a dozen objects beyond Pluto

Other Objects in the Solar System | Earth Science

The dwarf planets of our solar system are exciting proof of how much we are learning about our solar system. With the discovery of many new objects in our solar system, in 2006, astronomers refined the definition of a planet. Their subsequent reclassification of Pluto to the new category dwarf planet stirred up a great deal of controversy.

Our Sun: Facts

The Sun is the largest object in our solar system. Its diameter is about 865,000 miles (1.4 million kilometers). Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it. When it starts to die, the Sun will expand into a red giant star, becoming so large that
