Dwarf Planets

A dwarf planet is a celestial body that orbits the Sun and has enough mass for its gravity to shape it into a nearly round shape, but has not cleared its orbital path of other debris. The term "dwarf planet" was first defined by the International Astronomical Union (IAU) in 2006.

Characteristics of Dwarf Planets

• Orbits the Sun
• Nearly round in shape
• Has not cleared its orbital path
• Not a satellite

Examples of Dwarf Planets

Some examples of dwarf planets in our solar system include:

1. Ceres - located in the asteroid belt between Mars and Jupiter
2. Pluto - known for being reclassified as a dwarf planet in 2006
3. Haumea - located beyond Neptune in the Kuiper Belt
4. Makemake - also located in the Kuiper Belt
5. Eris - one of the largest known dwarf planets

Study Guide

To study dwarf planets, it's important to understand the characteristics and classification criteria set by the IAU. Additionally, familiarizing yourself with specific examples of dwarf planets in our solar system will deepen your understanding of these celestial bodies.

Key Points to Remember:

1. Dwarf planets orbit the Sun and have a nearly round shape.
2. They have not cleared their orbital path of other debris.
3. Examples of dwarf planets include Ceres, Pluto, Haumea, Makemake, and Eris.
