OUR SOLAR SYSTEMby Dominic Fabbri

  • Our solar system has two groups of planets, the inner planets and the outer planets.

  • Our solar system has 8 planets and 1 dwarf planet.

  • Our solar system contains a variety of objects. These include planets and moons, as well as asteroid, which are small and rocky.

Our sun

  • Our Sun is the center of the Solar System.

  • The Sun’s diameter is more than 1,000,000 kilometers.

  • It is the source of energy on Earth, and without it life could not exists.


  • Mercury is a small, rocky planet.

  • It is covered with many craters.

  • The planet is about the size of Earth’s moon.


  • Venus is the second planet from the sun.

  • The planet is also the brightest planet in the solar system.

  • Venus is the third brightest object in Earth’s sky. Only the sun and moon appear brighter.


  • Earth is the third planet from the sun.

  • This planet is the fifth largest.

  • It’s the only planet known to have life and the only planet whose surface is mostly water.


  • The nickname Mars has is the red planet.

  • Mars has huge dust storms that can last for months.

  • Scientiststhink that at one time Mars may have had water on the planet.

The asteroid belt

  • The asteroid belt is located between the planets Mars and Jupiter.

  • More than 7,000 asteroids have been discovered in the asteroid belt. Several hundred more are being discovered each year.


  • This planet is the largest planet in the solar system.

  • Jupiter has at least 63 moons.

  • For more than 300 years, a gigantic hurricane- like storm called the Great Red Spot has raged on Jupiter.


  • Saturn has rings that are visible from Earth through a telescope.

  • Its atmosphere is mostly hydrogen and helium.

  • Saturn has at least 31 moons.


  • Uranus rotates on its side as it orbits the sun.

  • The planet has at least 27 moons.

  • Uranus is one of the gas giants.


  • Neptune’s atmosphere is mainly made of hydrogen and helium.

  • It is one of the windiest planets in the solar system.

The dwarf planet pluto
The Dwarf Planet Pluto

  • Tiny Pluto has a rocky surface covered with nitrogen, ice, and small amounts of methane and carbon dioxide ices.

  • From the surface of Pluto, the sun looks like another bright star in the sky.

  • Pluto’s moon is about the same size as Pluto itself.

The galaxy
The Galaxy

  • A galaxy is a huge system of gases, dust, and stars.

  • Galaxies contain billions of stars. Our sun is on the edge of the Milky Way galaxy.


  • A comet is a ball of rock, ice, and frozen gases.

  • As a comet’s orbit brings it close to the sun, the sun’s heat may turn some of the frozen matter into gas.

The universe
The Universe

  • The universe is everything that exists in space.

  • There are many different galaxies in the universe.

Other dwarf planets
Other Dwarf Planets

  • There are officially 5 recognized dwarf planets in the solar system. They are Pluto, Eris, Ceres, Haumea, and Makemake.

  • There are another 6 objects in our solar system that are almost certainly dwarf planets and there may be 10,000 altogether.


  • A telescope is an instrument that is used to better view the sky.

  • The first telescopes were all refracting telescopes.


  • Constellations are a group of stars that create an imaginary picture in the sky.

  • In ancient times, people often gave these constellations names .

Other stars
Other Stars

  • Here are the names of some other stars, Procyon, Sirius, Barnard’s Star, Alpha Centauri, and Ross 154.

  • The 3 closest stars to our solar system make up the star Alpha Centauri.
