Some facts about the solar system for kids are that most of the solar system's mass sits in the sun. Planets Uranus, Neptune, Jupiter and Saturn consist of gases. The solar system has a variety of components, including the sun, planets, dwarf planets, moons and asteroid belt. Earth is one of the planets in the solar system.
The sun holds 99.86 percent of the mass that exists in the solar system. Most of the rest of the mass in the solar system exists in the planets. Of the gas planets, Jupiter and Saturn are closer to the Earth than Uranus and Neptune. They are also larger than the other two gas planets, Uranus and Neptune. Metal and rock make up the majority of planets Mercury, Venus, Earth and Mars. Dwarf planets in the solar system include Ceres, Pluto, Haumea, Makemake and Eris.
The asteroid belt sits between Mars and Jupiter. Some of the objects that make up the asteroid belt are very small while other objects have a circumference of more than 100 miles. The objects in the asteroid belt are mostly small pieces of rock or dust surrounded by frozen gas.
Earth travels around the sun completely every 365.25 days. Earth doesn't orbit the sun in a perfect circle; rather, Earth's orbit is an oval shape around the sun. Earth is the closest to the sun in January and the farthest from the sun in July.
