Solar System — Hello, World!

"Hello, World!
Look up at the sky. What do you see?"


Hello, World! Solar System


  1. Our solar system formed about 4.6 billion years ago, and it includes the Sun, planets, comets, asteroids, meteoroids and moons.  Watch a video and learn more about how our solar system formed!
  2. Everything in our solar system revolves around the Sun, which is a star — a massive ball of hot gas that gives off light and heat.
  3. There are eight planets that orbit around the Sun.  In order, going from the closest planet to the Sun, to the one that is furthest away, they are:  Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.  All of the planets are round.
  4. As of 2008, there are also five dwarf planets:  Pluto, Ceres, Eris, Makemake and Haumea.  In July of 2015, a NASA spacecraft named New Horizons arrived on Pluto after a very long journey and took amazing pictures of the dwarf planet.  Learn more about Pluto.
  5. The Earth is the third planet from the Sun, and it is the only planet that we know has creatures living on it.
  6. The Earth travels around the Sun in a loop shaped a bit like an oval, which we call the orbit. The Earth rotates on its orbit, and it takes one day (24 hours) to complete one rotation.
  7. It takes 365 days for the Earth to complete one full circuit around the Sun, which is what we know as one year.
  8. The Sun is 93 million miles from the Earth, but the light from the Sun only takes 8 minutes to travel to the Earth.  It would take Usain Bolt, the fastest man on Earth, a total of 450 years to run from the Sun to the Earth, if that were possible.
  9. The Moon is a ball of rock that orbits around the Earth, in the same way that the Earth orbits around the Sun.  It is approximately 239,000 miles away from Earth, and it is the only place in the solar system that man has travelled to from Earth.
  10. The biggest planet is Jupiter.  Jupiter is made of gas, and it is so big that you could fit 1,321 planets the size of Earth inside of it.  There is even a storm on Jupiter that is bigger than Earth, the Great Red Spot.  Jupiter also has an estimated 66 moons.  Learn more about what it is like inside Jupiter.
  11. Mars is sometimes called the "red planet" because the rocks that it is made from are red.
  12. Saturn is famous for its rings, which are composed of small pieces of ice and dust.  Like Jupiter, it is made of gas.
  13. The Sun is just one of hundreds of billions of stars in the galaxy that we live in known as the Milky Way.  The whole universe has at least 100 billion galaxies in it.
  14. For thousands of years, humans believed that Earth was the center of the universe.  Astronomers such as Nicolaus CopernicusGalileo Galilei, Johannes Kepler and Isaac Newton helped develop a new model that established the Sun as the center of the solar system and the movement of the planets around it.

Do you enjoy learning about our solar system?  Astronauts have left their footprints on the moon.  You may just grow up to be an Astronomer or an Astronaut!
