Introduction

Planets are round objects that move in circles around stars. There are 8 planets in our solar system (including Earth), and 5 dwarf planets. These planets move around our star, which we call the Sun.

The planets

Here is a list of planets in our solar system.

Mercury: Closest to the Sun, this planet gets both very hot and very cold.

Venus: The brightest planet in the solar system.

Earth: The third planet from the Sun and our home - it's unique in many ways.

Mars: Sometimes called the ’red planet’ because it’s tinted red by rusty iron.

Jupiter: The largest planet, more than 300 times larger than the Earth.

Saturn: The second largest planet, which is surrounded by rings.

Uranus: The seventh planet from the sun, with 28 moons (that we know of).

Neptune: The planet farthest away from the sun.

Dwarf planets: Pluto, Ceres, Eris, Makemake and Haumea.
